Would a Base Cayman be a huge downgrade from a Base C6 Corvette?

Does anyone here do HPDE in a majorly underpowered car for your run group?

I do HPDE with the Porsche Club, and my run group has everything from Cayman’s to GT3 RS’s. My 430hp Corvette leaves me near the bottom-middle of the pack. It’s slow in the corners, but holds its own on the straights. Annoyingly, I burn through a s et of brake pads after just two weekends, which is getting old quickly .

Thus, I’m considering buy ing my first Porsche!

My budget is $30K, and I’m only looking at post-IMS models (so 2009+). The Cayman S hasn’t quite depreciated enough, and they’re rare as hens teeth. I guess not many people were buying Porsche’s during the Great Recession. But there are a handful of 2.9L base models.***

Here’s how it compares to my Corvette:

Base C6 Corvette

6.2L V8

430 hp / 424 lb-ft

3217 lbs

Brakes the size of kiwis that need new pads after just two track weekends

Base 987.2 Cayman

2.9L H6

265 hp / 221 lb-ft

2954 lbs

Same brakes as the 987.2 Cayman S (yes, really! Except the calipers are painted black instead of red)

Pros: Larger brakes with fixed calipers for quick pad replacement, lower curb weight, superior handling, slower depreciation, and it’s actually slow enough that I’d probably never have to lift off the throttle when giving the pass signal.

Cons: There are faster-moving glaciers, less torque than a salamander, no more V8 noises, and always being outshined by my dad’s GT4.

What say you, Oppo?

***There are a few 981 base Cayman’s, but the 981 is actually a bit slower thanks to less torque from it’s smaller engine (only 2.7L) and cripplingly tall gearing (78 mph in 2nd!). Plus it also has electric steering, and smaller brakes than the 981 Cayman S.

The Cayman is almost certain to be slower around the track than your Corvette, right? Maybe your local track is small & tight enough for this not to be the case.

Is there a regulation  against putting bigger and/or better brakes on the Corvette? Because that would seem to be the easiest solution.

I’d look at power & brake mods (if any) before trading out of the Vette.

I’d personally go for an earlier Cayman S that has either had the IMS issue replaced or have it replaced yourself. The earlier Cayman S is plentiful in the low 20K range.

Not to be the WhackJob of the Group... but for that kinda money you could almost stretch into a 996 Turbo. Which absolutely did NOT have the IMS issue (had the older race-bred engine cases and valvetrain) and which absolutely will out accelerate and out brake and out corner your C6.

No disrespect to your C6, which is a great car, but this is a real wolf-in-sheeps-garb here...

This is at VIR (huge track, also C6, not C5, vs S, not base).

So, not helpful at all. =)

I’ ve considered g oing that route, but the fact that I keep thinking about the Cayman tells me I’m going to end up buying one eventually. I’d hate to spend $3K+ on a big brake kit  only to end up trading it in on a Cayman a year later.

I guess the third, and more expensive option, would be to throw lots of money at AP Racing and LG Motorsports.

IMS isn’t serviceable in any Cayman, its M97 required the case to be split.  Pre-2005 cars have the serviceable IMS bearing.

I’d upgrade the brakes in the Vette before buying a base Cayman.

Hmmm, that is inconvenient . I would still buy one though. The odds of actual failure are still very low.

Oh absolutely - failure rate is extremely low. IMS shouldn’t scare anybody away from a 2005.5+ P-car, and in the older ones where it is scary, it’s serviceable.  Win-win.

Related to what Token_liberal said... Have you tried upgrading to carbon fiber-ceramic performance brake pads?

Or upgrading your pads/roters/calipers to s omething like this brake upgrade kit?

I’ve been using Carbotech XP12 pads. The stopping performance is great , and no fade, but they still wear out quickly. Big car, small calipers/pads.

So, first question is: is this a track and daily car, or a track/weekend car? If it’s a daily and a track car, the Porsche is a much nicer commuter.

Second question: how have you met our lord and savior the BRZ?

I instruct with the local PCA (as well as BMWCCA, SCCA, and a couple other groups) and I can go out and run my BRZ and keep up well enough not to worry about being down on power.

The base Cayman/Boxster is a little faster than a BRZ, but not by enough for me to consider upgrading (I love the Cayman and if I wasn’t a public school teacher, I’d have one). Now, for $30k you could get a 2015 BRZ (late enough to have all the issues worked out, but early enough to be in a good depreciation spot) and upgrade to wherever you want to be.

There are a couple of supercharger kits that will make the BRZ as fast (on track) as your Corvette (Jackson Racing or Edelbrock are the way to go, both run $4-$6k depending on setup and how much wrenching you do yourself ) . The sweet spot is about 300whp (on e85) , more than that is costly in either necessary upgrades or reliability. The kits add 80-120lbs depending on which and what ancillary parts you put on. With a full interior and without much effort you’d have a 2700lb, 300whp track destroyer that out corners and brakes just about anything and with enough oo mph to keep you from getting bored in the straights.

My BRZ only has a header and tune for power, with a might y 178whp (about 15hp over stock) ! I have a blast with it and track it all the time (30 trackdays and 10 autocrosses last year, and I’ve got over 40 trackdays and 9 autocrosses planned for this year). A set of 200tw tires cost me $600 -$700, and my consumables come out to about $100 per track event plus gas and entry fees (you’re probably closer to $300 in your Vette) . My car’s been very reliable and I can fit a full set of tires and tools with the seats folded down, so road trips to distant tracks isn’t a problem.

Passing Corvettes at 8min and 14min marks (I was running the classroom portion of the DE, so I had to run in the “intermediate group” so there’s a pretty big skill gap :

If the BRZ is too plebeian, I’d rather spend more and/or get an older S than a non S Cayman. The additional resale value should negate any initial price difference and the Cayman has enough of an underdog aura that going with the slower one is just doubling down. I’ve driven both on the track and just about all the generations, as long as we include Boxsters, and I didn’t think the non-S was particularly under powered but it was noticeably slower than the S and wasn’t quite in the same speed category .

All the options are going to feel slow ( in a straight line) compared to your Corvette, but they’ll all handle better than your vette and be much cheaper to run. But, if you pass someone in your BRZ you feel like a champ and if anyone (other than a Miata) passes you, you don’t worry about it since they’ve got the faster car (few people differentiate between the S and non-S Porsches on track, so that’s a ding against them, and if you do add a supercharger to the BRZ you lose just about all your bragging rights).

Oh, I hear you... but have you driven a 996 Turbo Tip?

I have and it’s pretty amazing. I love my 993 Turbo (6MT) , but the 996 will walk all over it... Tiptronic or not.

The 996 Turbo is actually on my wishlist-- it’s amazing value for money.

Hmmm... I’m seeing in the description of that pad is that it’s “Rotor friendly”

https://store.windingroad.com/carbotech-xp12-brake-pads—-track-p1946.aspx

Which sounds like to me that the pad material is designed to give up its own life more so that the rotors will last longer.

Have you tried any Ceramic or carbon-ceramic pads?

They aren’t too far off in pace. Same tire compound and drivers and the Corvette is faster but not by so much that driver skill couldn’t close the gap.

Plus, trackdays are about having fun. There aren’t any trophies and in my experience, it’s the cars that over- perform their stats that impress people more than the absolute speed of a car (except for the very fastest car and driver).

One other thing to consider is that the 2.9 didn’t have DFI, whereas the 2.7 in the 981 did. There are quite a few simple ECU mod s available for the 981 that bring you up ~ 20/20 in hp/torques. (There may be some for the 2.9 but I recall DFI being easier to tune.....?)

Is the 987 gearing that much shorter than the 981?  (PDK helps somewhat on both models)

Not sure how much street driving you’ll do, but personally I think the 981 interior was a huge jump over the 987. That will not help you on the track other than parade laps!

The overblown concerns about the IMS bearing makes the 2006-2008 987's and 997's a real bargain. They also dramatically overshadow the real issue with the engine...the potential for bore scoring.

I agree, but if you’re running in groups with limited passing zones (in select straightaways - all but the top/instructor class ), it’s going to be a pain in the ass to keep getting held up in the corners by “faster” cars who can then leave you in their wake in the straights . Granted, it will feel even more amazing when you finally get a pass done and make it stick...

Similar situation with having a lightweight but underpowered car on twisty backroads. All fun and games until there’s a car in front of you really holding up progress. Having the power to get around quickly and safely in a short passing zone is awesome.

Upgrade to a 3.6 or 3.8 L when they die! It’s an ‘easy’ swap for 2003-08 models which didn’t require a re-map of the DME.

* Easy does not really mean easy, just ‘easier’.  N or does it mean cheap.

2004. It was my “wall poster, gotta have” car and I was feeling flush when I saw it turn up in an out of the way spot on the interwebs.

I ended up buying a couple of other early air-cooled P-cars in that same timeframe (a ‘68 912 and ‘ 77 coupe with an SC motor and Euro ride height ) . Wish I could say I had foresight, but I just found them interesting. Still do in the “more fun to drive a slow car fast” philosophy. They’ve all been a riot on vintage rallies. And, reliable, in a twisted way. Much, much more dependable than my modern Audis, which have gotten ridiculously complex .

You still do owe OPPO a big write-up of your stable(s) with photos and everything, you know. =)

Being able to participate in vintage rallies would be awesome. My E90 M3 is also ridiculously complex, but it would take a lot for me to part with her at this point. Pretty bonded now, after 8 years and 85k miles in my possession.

I’ve sort of been trickling them out... I posted about that FJ40, which I love. And, did show the (fugly) X1/9 on the project list.

I’ve got a video to post (FZJ80) for Hammerhead Fistpunch, which is intended to completely blow his mind. Just last night I was looking at the Cruise Moab details for April— may take that Cruiser over there for grins. It’s got a nice lift, Old Man EMU set-up and skid plates off a battle cruiser.

The Impala (Grand Sport 5.7L and Tremec T-56 ) is still kicking my ass with a bizarre issue, so I’m due for a post on the “Many Ways I Despise Opti-Spark”.

Try upgrading to a more track oriented pad (XP14 or 18), you shouldn’t be going through pads that fast so you must be overheating them.

I get 6-10 days out of my pads, lighter car and a big brake kit, and most of the track guys I know get about the same after they figure out what pads work for them.

I was extremely close to upgrading it this winter (big brake kit, foglight cooling ducts, race seats/harnesses, camber, etc). But the fact that I keep searching for used Caymans tells me that I’ll end up buying one at some point regardless . I just know I’d spend $3-5K on upgrades only for a really well-priced Cayman to show up.

BTW, I’m not selling 996 Turbos, but I was genuinely shocked at how taut and mind-blowingly fast that one I drove was.

I love the 993T, but that 996T is in a completely different league. Actually reminds me a bit of the New Age GT-R in terms of absolute poise and just comic-book fast. Maybe a little detached in “feel” but oh, man, is it just an animal on boost. A big, scary, fast animal.

In the groups I’ve run with, they are usually pretty good with the flags, especially if they see it a couple laps in a row, but it does take a certain “swallowing of pride” by the driver in the more powerful car, especially if it means they have to not take the pass back (even if they theoretically could) on the following straight. But if someone’s repeatedly in your mirrors, you gotta lift and let ‘em go. A fter a couple turns, it becomes obvious who’s faster.

Some of my favorite sessions are when I find a friend who’s very close in pace and we can spend the session trading spots. My least favorite sessions are when I get stuck behind a Corvette, Mustang, or BMW (usually one of those) who refuses to give the pass and/or doesn’t lift when they give the point-by.

A Corvette would bankrupt me, I’d have to cut back to less than half the track days I do and there’s no way that the Vette would be twice as fun as my BRZ (it’d have trouble matching the BRZ).

I set a new PB at my home track last weekend, I had no fewer than 5 people tell me how impressed they were with how fast I was in my BRZ. If I was doing as well in a Corvette I’d be surprised if any of the other instructor/advanced drivers I was with would have been impressed. Fast cars are supposed to be fast. Slow car fast is where it’s at.

I really like mine and I’ve convinced a number of people to pick them. They make great track cars and hard to beat as a pure driving experience.

If you aren’t having fun with a BRZ, you aren’t doing it right. I instructed a teenager at his first trackday in his BRZ and he had a great time. His dad came by at the end of the day (or at least that’s when I met him) and the first thing the kid told him about was passing Corvettes. My student had the biggest smile you could imagine.

I tell a lot of people if I were smart I would have got a base 981 and spent the difference on track. But, circumstances didn't allow that and the S I have is fucking amazing anyway. Idk if the smart thing financially is for you to get a new car, but after almost 2 years in my Cayman I'm very glad I went with it over the C7. Even on the track getting passed.

Two of my friends in our backroadtrip group have them (one Scion, one Toyota). Always impressed with how they perform, and I’ve always liked the way they looked. Loved “slow car fast” in my Mazda, but it would be an adjustment coming from 450 hp! Would love having a car that was at home on an autox course, though.

Things that are less than thrilling about the Cayman:

Open Diff, limited suspension adjustability (I think you need adjustable control arms for big changes), struts in the rear means suspension can do interesting stuff when it unloads (heavy braking).

But I still really really like them. I like them just as much as a base C6. It would be hard for me to pick between the two.

Ah, so you’re the guy who posted the awesome BRZ onboard videos last week!

I have nothing against the BRZ, but I have some bad blood with my local Subaru dealer after my 15' WRX kept going into limp mode on the track. I didn’t tell them I was tracking it, but they read between the lines and politely/firmly warned me that they’d void the warranty if I didn’t fuck off . I ended up just selling it and buying as much Corvette as I could with the money.

Speaking of the Corvette, I don’t daily it, but do occasionally drive it on the road (mostly to/from the track and to/from car shows). I’m really afraid to upgrade it because I know I’ll keep looking for Caymans, find a really well-priced one, and never make back the $3-5K worth of upgrades when selling the Vette.

I’ve kinda gotten the point where the novelty of hitting 130, 140, 150 mph is wearing off each time I burn through another set of pads from all the extra braking. Plus now that I’m in the intermediate group, I realize that I’ll NEVER be the fastest car out there. Someone else will always turn up in a GT3, GT2, Turbo, etc.

marshknute > BeaterGT 01/13/2020 at 19:02

Not at all. Bone stock except for pads/tires.

I’ve been afraid to upgrade it because I just know I’ll eventually find a well-priced Cayman in the near future, and I’ll never make back the $3-5K worth of upgrades when I sell the Vette.

What are Hawk HP+ pads made of? Ferro-cerramic or something like that, if memory serves? I used to use those, but found they squealed louder than Carbotechs and made a horrible “gravely/grinding” noise for a week or so after finishing a track day. I didn’t notice any difference in performance or pad life between the Hawks and Carbotechs.

Reading some of your comments, it sounds like you have definitely been bitten by the Porsche bug. Trust me, once that happens, there is no coming back until you satisfy that urge haha. So it’s best to not spend any more money on upgrading the Vette. I would definitely try to save up for an S or go with a 987.1 S. While Gt3s and the like will still walk away from an S on long straights, I’ve never felt THAT undermatched in my 981S vs most of the cars at PCA HPDEs, especially with how balanced the Caymans are in the corners

Guilty as charged.

Dealers vary widely, mine knew I tracked the car and happily did all the warranty work I wanted (and some I didn’t even expect or think they’d do). The only problem I really had with them was that they weren’t great at diagnosing problems (they weren’t used to track conditions or what fails from them) so I’d often come in with a diagnosis from one of my track buddies (usually one or more were mechanics and/or been wrenching for a long time on their track cars) that turned out to be spot on only to have the dealer initially think it was something else or not be able to figure it out the first time.

They were very nice and didn’t charge me for some stuff they could have and passed on all my warranty stuff with their endorsements, so it was hard to complain. But since my warranty expired I’ve done all the work myself (with my mechanic friends’ help of course).

You’ll learn more and faster in a slower car, plus with lower cost consumables you can track more often which will make you faster. Nothing wrong with a Corvette and I’d never fault someone for picking one, but those big tires are expensive. Speed costs money, you just have to pick how fast you want to spend.

Why not upgrade to ZR1 calipers, new rotors, and some stainless lines? Add in some suspension pieces. Then see how you compare.

Why not look into a C6 Z07? Zo7 was a Z06 with ZR1 brakes.

My daily driver 2012 Cayman S (987.2) is likely going to be for sale soon due to the birth of my second child. It’s a PDK w/ sport chrono and the track-desirable limited slip differential option like the Cayman R. I’m the second owner. The price would be way under your budget if you don’t mind the 125k miles... I’ll also throw in 2nd set of pristine wheels. Do you like Aqua Blue Metallic?

Use the ‘Vette in the straights and the Cayman to get around corners. One is more important than the other.

OR , you could buy like 3 Citroen 2CVs and have just as much fun going ridiculously slowly :P

I’m fine with tying them together, but do I need a codriver for the second car, or am I supposed to jump from one to the other on the move like in a F&F movie?

The set of ZR1 calipers/rotors is $10K.  They’re the same brakes found on the Enzo!

I purchased my 2010 cayman s for $29, 500 so it can be done. It had 80k miles on it, but maintenance was up to date and it had recently had a clutch put on and new shifter cables. Sounds like you ar e aware of the advantages of the 987.2, dfi engine, better cooling, vastly better oil system. Mine is a manual, black interior, which were must haves for me. Just keep an eye out, and act quickly if you find something. I’m in ohio and found mine on craigslist in Ne w Hampshire. Flew to Boston the week after finding it and caught a bus to NH.

I assume those numbers based on redline in each gear?

The base 987.2 and 981 have nearly identical gearing....and as far as I can tell the additional 200 rpm @ max HP for the 981 should only account for ~2 mph difference in 2nd gear assuming tire sizes are the same.

(Not that it holds much weight, but the 981 was .1 sec faster to 60, which I’ll assume is in 2nd gear)

I can’t find the redline for the 987.2, but was curious why the top speeds in each gear were so different.

You can get the calipers for 1500 from here.

The full carbon rotors are pricey, but I do see some metal ones that are much cheaper that will fit.

So not 10k unless you go through GM.

Btw, what brake pads do you use at the track, and how long do they last ? Are you still on the stock rotors/calipers

I upgraded to the AP Racing sprint kit (front rotors and calipers), mostly for weight savings and cheaper pads. Front pads last 6 to 10 days depending on the track and rear s ar e stock and last twice as long as the fronts.

For pads I switch between Ferodo ds1.11, GLoc R10 or 12, and hawk dc30/dc60 depending on price/ availability.

I don’t currently have any ducting but i don’t get fade with any of the pads I listed. Typical days are 6 twenty minute sessions and the longest day was 8 thirty minute sessions (I’ve done h our stints without issue). It's not uncommon for me to run full back to back sessions.
