So, without Googling it, how big do you think the front brake rotors on my Jetta Sportwagen are? 250mm? 265mm? 275mm?

Nope!

312mm front, 272mm rear

Is that insane or what?!

I just looked it up, my WRX (with the 4-pot/2-pot setup, not Brembos) are 294mm front, 290mm rear. So yeah, damn.

Sounds sporty and wageney. Pretty good vs. curb weight. I'm going to have somewhere around 250mm in the back of my project and 290 up front, because both of my parts donors are >4000lb vehicles. Heh. (~2500lb car)

lol I'm pretty sure mine are single piston calipers all around :P

Gotta love GTI brakes though! Although some loon was crazy enough to swap a set of R32 brakes on to his JSW... 345mm front and 312 rear!

Mine are 302 mm front/ 316 mm rear, but they're only 2/1 pistons.

Single piston calipers all around though :(

I need these!!! 352mm Cayenne with 6 piston (!) calipers!

JK Wrangler

LOL that's because it's like 5k lbs right?

Aaron M - MasoFiST > Sportwägen, Driver Of The Red Sportwagen 12/02/2014 at 17:50

Yeah, mine are just small enough that I can downsize to 16" wheels and still fit the brakes. Because rallycar.

Sportwägen, Driver Of The Red Sportwagen > Aaron M - MasoFiST 12/02/2014 at 17:52

Mine came stock on 16s :P

I'm looking into getting some 18x8 or 19x9 wheels for it eventually. At least the brakes aren't tiny like on every corolla rolling on 16 or 17" wheels ;)

i'm sure this car is quite a bit heavier than wrx though

BrownMiataDieselWagon > Sportwägen, Driver Of The Red Sportwagen 12/02/2014 at 17:52

Yep, 4880 lbs. 500 more than your wagon.

Sportwägen, Driver Of The Red Sportwagen > BrownMiataDieselWagon 12/02/2014 at 17:54

wat

More like 1500 lbs (or more)... My wagen is only 3200 curb weight (that's what it says on the door tag)

Aaron M - MasoFiST > Sportwägen, Driver Of The Red Sportwagen 12/02/2014 at 17:55

The real problem is that Subaru offsets are kind of dumb...I think there are 15" Compomotives that fit over the 4-pot/2-pots, but only in +55 offset.

12 1/2 inch front, 11 inch rear. Not that big, if you really think about it.

Just looked it up, and both a Jetta Sportwagen and a GD WRX weigh between 3200 and 3400 lbs.

BrownMiataDieselWagon > Sportwägen, Driver Of The Red Sportwagen 12/02/2014 at 17:57

Oh. I thought we were comparing gross weight. GVWR is 4880, ~5K. Curb weight of the Jeep is 3880 lbs.

For one of these?

Yeah, I think they are quite large considering what the car was intended for :P

Sportwägen, Driver Of The Red Sportwagen > BrownMiataDieselWagon 12/02/2014 at 17:59

Oh, then yeah, 500 is about right...

261mm front/283mm rear with 4/2 pistons on the 245. So racy that the Lemons car uses stock rotors and calipers.

You know what would be crazier? TTRS brake swap. 370mm, 4 pistons. Too expensive :P

Sportwägen, Driver Of The Red Sportwagen > Nife - dat Wheelspin 12/02/2014 at 18:03

Oh, I was going to say a Cayenne stage 5 front swap from ECSTuning... 352x32mm 6 pistons! $2.5k :P

That's really not that uncommon, pretty much standard actually.

Sportwägen, Driver Of The Red Sportwagen > tromoly 12/02/2014 at 18:07

But the standard Golf TDI has 288mm front brakes though... hell even the Veloster Turbo only has 299mm front brakes!

SHIT! At that price if someone does a big brake upgrade and doesn't track their car. I'm under the impression that they are doing it for flaunting purposes.

'Yo brah! Check out ma brakes they way bigger than yours'. (infact I know a guy who is obsessed with comparing brake sizes, Cracks me up..)

My dads Q7 has that 6 piston setup, it's a heavy car it needs it!

How about those sporty wagon brakes? (Your rotors are still pretty impressive. Stock VW stuff?)

Sportwägen, Driver Of The Red Sportwagen > Nife - dat Wheelspin 12/02/2014 at 18:22

I want that 6 piston setup! I do track my car (sort of). I autocross it regularly!

Sportwägen, Driver Of The Red Sportwagen > redblockpowered 12/02/2014 at 18:24

Yep. The wagon is completely stock (for now)... It still gives GTIs a run for their money at the autocross (I run about 3-5 seconds per lap slower than the modified 04 GTI with 245 tires and bigger brakes) First upgrade? Either coilovers or front and rear swaybars!

303mm front. 280mm rear. So close. Single rotating piston each for me.

For the Murdersofa?!?! WTF GM actually made brakes that big besides for the Corvette?

Jake - Has Bad Luck So You Don't Have To > Sportwägen, Driver Of The Red Sportwagen 12/02/2014 at 18:35

I suppose. A C5 corvette has 325.12mm rotors.

The murdersofa is a lot of mass to stop, and safety was its key selling point, so big brakes were a must. I need $80 so I can get slotted/cross-drilled rotors up front to help with the horrendous brake fade I have.

I need to get some stainless steel brake lines to help counter the mushy pedal ;)

I've considered it, but I care more about effectiveness than feel :P

My brakes are very effective :) I even took a video this afternoon of a 60-0 test! I didn't upload and post it because it ended up being sideways and very... grainy to say the least :(

However the 60-0 took about 4 seconds ;)

Nice. I need to do that. My new tires are so sticky that my brakes can't actually get them to break loose when I stomp on the brakes.

280mm front, 295mm rear on my wagon (Volvo 850 T-5).

Though IMO the car is horrendously under-braked considering a) how fast it is and b) how much load it's made to carry. I'm not sure if my particular car's braking system is just in need of attention (the front rotors are definitely a bit warped and the fluid looks a little on the dark side) or if the brakes are simply not good enough from the factory, which sounds really odd, considering Volvo's concern for safety. I've heard of fellow 850 drivers complaining of the same lack of braking power though, so I'm considering upgrading the brakes in a few months, once I overhaul the entire system.
