I'm interested in getting a set of KW street comfort c/o's for my E90. From what I've read so far they, are amazing for DD'ing and the handling is improved immensely. I also plan to install some M3 suspension bits. I can get them for a decently good price from a Vendor on a forum. The only thing is, I have no experience with coilovers. Now, I know how to install them, how they work, but that's about it.

Anyone car to chime in/ tell me why springs & shocks are a better idea?

Springs and shocks/struts are less expensive and easier to install, but not as adjustable. You don't want cheap knock off brand coilovers.

I echo the not buying cheap coilovers advice. I have ridden in cars with cheap coilovers. They are teh major suck.

Not to mention dangerous as fuck.

You don't want to be driving down a road and have your coilovers go out on you.

if you are looking for comfort... I'd say springs and shocks. They can normally be had for less than a set of coilovers. No you will not be able to slam yo ridz, but you'll have an e90 that handles much better and is far more comfortable. That being said, if you have the need to slam your ride, coilovers are the ticket for you.

you're likely going to have a similar ride. spring/shocks, like already mentioned, are cheaper and you have to live w/ the ride height preset. You can't corner balance either...

don't forget added cost of rebuilds and the downtime that will mean for the car (if it's your DD).

KW makes good products, highly regarded in the BMW community (and those guys are usually douches, so that's how you know they must be good).

They are only cheap because a Vendor on the forum sells them (brand new) for about $500 less than what you pay if you buy them straight from KW. KW has a markup on them, and vendors are given a price that they are allowed to sell them for but they don't advertise that price, you get in contact with them.

Not slamming my ride is exactly why I want coilovers haha. For the price of a set of springs/shocks that'll give me the perfomance/comfort of the KW street comforts I'm just a few hundred under the coilovers. And that's with a ride height much lower than I want, I don't want my wheel to be tucked into the wheel well haha.

As the owner of many tracked BMWs including the E90, I wouldn't pay for coilovers unless you absolutely want the lowest possible drop or require the ability to fine tune your suspension by constantly changing spring rates and corner balancing. Those are features for those who find themselves on the track every weekend.

My suggestion is to find a quality spring kit that provides the drop you're looking for and then buy a nice shock and strut package to match. Single adjustable Koni Yellows are probably more than enough.

ah, well then is sounds like you've done your research and I cant say anything bad about KW's since I LUST after a set of V3's for my suby. I'm surprised eibach, H&R, or someone else does not have a set of good springs that will not slam you car. That being said, height adjustability is the only thing you get with coilovers over a spring/string combo.

Yeah, I'm looking at reputable coilovers only. The bonus on getting coilovers is that I can sell them if I ever get rid of my car.

Springs/shocks that'll give me the perfomance and comfort of the coilovers are non existent, or very expensive (just a few hundred under the coilovers). And that's giving me a ride height much lower than I want.

Haha you could always ask a vendor, they can give you a nice price. $1489 shipped.

The $200 I paid for my pair of struts killed me last month, so I don't think I'm quite there yet... Thanks though.

Yeah the KW's have some other goodies that make them handle better/more comfortable. But it's pretty annoying how I can't find a set of springs with equal perfomance that doesn't cause 18" wheels to be tucked into the fender.

Coilovers are great, but I wouldn't mess with a China or Japanese brand (also made in China). KW's are the real deal. I'd look to see if they have tender springs (2 springs each) to take up the overtravel. This reduces the noise of the spring clanking around when the suspension is under full droop.

Honestly for most cars I feel like coilovers are overkill.

If maintaining ride comfort is a priority, you should take a good long look at Koni FSD shocks paired with either Eibach Pro-Kit springs for a conservative drop or H&R Sport for a bit more of a drop.

Many people who have the FSDs say they ride better than stock, even with lowering springs.

Then you can take the money you saved on not getting coilovers, and put it toward thicker sway bars.

welcome to the hellflush movement. Do you have a coupe or sedan?

Thanks for the heads up. I believe they do, as most reviews say the street comforts were much quieter than most C/O's.

No worries, I recently had to shell out some cash to get a new windshield, my wallet still hurts haha.

Koni shocks with an eibach pro kit was my first choice, until I got to track a car with KW coilovers haha. I'm gonna have to see how everything goes. If I can afford the C/O's I'll go with them, if I end up buying the M3 parts first (not an M3 sway Bar, those are actually really thin) and a lighter set of wheels I'll probably end up going with springs/shocks.

Here's a good tip: don't go oem. The oem glass bmw chose to use is really soft, and it pits really easily. I went aftermarket and it's much better. (Cheaper too)

Yeah, I'll likely go aftermarket. Good to know.

A well done sedan does make my pants tight (especially since I love the m3 coupe body over the e92 skinny body). That being said, what about these springs and these shocks ? Those were and still are "all the rage" on the e36 and e46 cars. Great performance, good comfort and a heck of a lot cheaper than coilovers. That setup will save you ~800 on those KW comforts, and you'll avoid being slammed.

Well the Koni FSDs are sorta special compared to regular Koni Sports. The FSDs have this adaptive valving dealie where they adjust their response depending on the strength of the bump they receive. So they're soft most of the time when they get a short jolt, but firm up when you do something that's more of a weight transfer thing like take a turn or hit the brakes.

I've heard a lot of good things about this setup. I'm not an xi so I'll have to look up the RWD H&R sports. But this does seem like a good alternative, thanks! The money saved can still be pissed away on mods too haha!

ack, sorry about that, I'm sure they have versions for your E90. And yes, that $800's will buy you some m3 control arms, or new bushings or part of a diff!

No worries, just a few clicks and I found them! And yeah, this is starting to look much more appealing than coilovers.

A nice set of Bilstein HDs and some nicely matched springs will likely do the trick for a lot less than a set of KWs will
