Big Brake Mod (Brembo, StopTech, Wilwood) 13"/14" Front Discs

There was some discussion on Regalgs.org about bolting Cadillac CTS-V calieprs to our cars. It was pure specualtion. Well..............I got to thinking and.............





Thats my old 12.7" rotor in there

F-body guys have been doing it. Using a C6 corvette Z06 Rotor (14")... Can it be done???I still don't know, there is a big opstical I ran into.




I need 18" Rims with a BIG offset.


Opinions?

Also anyone have any ideas for the rims?

I dunno about rims but honestly, that's insanely cool! Make it happen!

I always have loved Boss 318 in 18". If i didn't find a deal on the PAU rims , I'd have picked up a set eventually....maybe still will one day when i make a bit more money.

Otherwise...DO IT!

my only question is, what kind of tires can keep up with the massive deceleration? my 8" T/A break loose in a heartbeat if i nail the Fbodys.
you're gonna need r compound tires to keep up
as for the rim's i'm partial to the sts 18" rims, but you may need a spacer to give clearance.

side note: any luck on a rear brake upgrade? the 80/20 brake distribution feel more like 95/5 now :/

With my 255 50/17 falkens it is very hard for me to lock them when my ABS fights to keep control.


Rear brake upgrade I beleive could be done with Bonneville GXP/ 03-05 PAU rear brakes . Same caliper as our buit the bracket is larger to accomedate a 11.7" rotor. I thought about just changing the caliper brackets on my car.... But Gm wants $80 per bracketr from those year cars.

Anyone want to find me a deal to some caliper/ brakcets I mentioned above. My rear brakes need attention anyway.

looks like you need bigger rootors.
as rims...well...uno buyed 2 days ago for hes SSEi some nice 18'' Tomason NT4's
looks nice and its a good strong rim for heavy car.

Tirerack has silver sport edition ST3's on sale for super cheap, for the Riv. I'd assume they'll work on the SSEI as well.

edit - Where did you get the CTS-V calipers from, and how much did they set you back?

I checked Rock Auto and they only have the rears

BTW what's the difference between the CTS-V brakes and the Camaro brakes? I'm surprised they aren't the same or nearly the same.

The CTS-V brakes are four piston brembo calipers designs for a 14 inch rotor IIRC. The camaro calpiers are two piston designed for a 12 inch rotor.

Timo, you mean these?




Those rims look really good, I'd look into those if I were you oldsman. Check and see if they have the right dimensions, they'll look great!

yeah those rims i meaned ...will make a picture later and show how they look under the ssei.

Does anyone know if the Thomason wheels are available in the US?

Paid $300 shipped for them with pads included.

The rotors are either 13.4 ich or 14" I need to test fit to find out..

I would love to see those pictures!

What caliper bracket are you using for that?

Its part of the caliper.




A link to the regalgs.org thread for more info.

Well here some pictures of the new rims...duhh i dont know what uno was thinking...BLACK!..not suiting there..imo...but i will talk him ower to paint them white!
ohh and btw its a older ssei then yours..forgot to tell you that before..








Should have buyed same color as the tomasons on mine..

The black rims look great. Trust UNO . . .

Stupid question - will the 6 pot Brembos on the new CTS-V work?

Try them and let us know.!!!!

Gotta get my 18's first - well maybe I should research the brakes before that. Might need 20's to clear them!

Brembo is working on bringing the ZR-1's ceramic rotor technology to the mass market. Imagine a Riv with ZR-1 brakes for a moment . . . Man have we ever got to figure out a better braking solution in the rear!

Hey, where does one get these CTS-V calipers at? I looked on Rock Auto and they only have the rears Trying to get a price on 2nd gen front calipers.

A parking lot or someones garage (j/k)

4 real, no one around here has a ZR1 or CTS-V

Do the CTS-V calipers weigh more than the F body calipers? How much more does the 14" rotor weigh over a 12" rotor?

most FWD mid-full sized GM's = 5x115 bolt pattern
all late vettes and F-body's = 5x120 bolt pattern

I don't think the 14" rotor will fit our hub and it doesn't look like that 12.7" rotor is gonna cut it for that cts-v caliper

The hubs are not interchangable between the two cars either. I'm pretty sure the size fitting into the spindle is a little different.

Any other options anyone knows of for the rotor? I could see maybe a 2-piece hybrid rotor but that would make the mod extremely expensive.

Oldsman nevermind I guess - too much guesswork for one white boy with no money

I;m looking at black rims for my white riv. Seeing that prix does not change my mind.

To the naked eye it looks like it will work i ordered a Z06 rotor to see if it will fit on our studs.
