CTS-V brakes, something different
#621
This would be ideal because I would only need to move my wheels out 1/4" vs the full 1/2". But it sounds like I would need to use a 2-piece rotor with the f-body offset, which means $$$$.

I just checked the part numbers on gmpartsdirect.com the number listed for the camaro caliper is $83/each and the number listed for the G8 GXP is $216/each. There must be something different, can someone verify this?
acarnut can you provide us with more information other than the smaller bolt holes in the camaro caliper?

The Camaro calipers are cheaper, but make sure you comparing prices for the calipers with or without pins. The US$83 price does not include pins.
I am on another board (pm for link) where the Pontiac G8 guys are all over this upgrade - and the gm parts dealer there offers a 'kit' where switching from the GXP front calipers to the SS version knocks almost $200 off of the conversion. It also looks like the Camaro SS rear brembos are a bolt-in for their rear suspension (the GXP does not get 4-pot rear calipers).

I'd suggest looking at the larger C6 Z06 Vette rear rotors at 13.6" (340mm). I believe the drum parking brake size is the same as the F-body. This is the biggest rear rotor I know of unless a company makes an larger upgrade rotor for that car.

acarnut so that being said, its a direct bolt on besides for the size of the bolts. So I drill the spindle to and tap it to the bigger size, then use the new camaro rotors? stock? Im confused on the rotor part, I do have BMW style wheels in a +35 so rubbing wont be and issue.

Then you use Z06 rotors. AFAIK the new Camaro SS and Pontiac GXP rotors have not been tested - they might fit better (eliminate the spacer washers) or not, but my wheels will clear them regardless, so I won't be chasing this any further.
Wheel spoke clearance is the issue, not offset. See the earlier posts to this thread.

the Camaro caliper is threaded for larger bolts which requires drilling out your spindles.

Ill stay posted on the camaro SS and GXP rotor test fit.
Thanks

has n e one started looking at the brembo rear setup for the f-body? is it cost to get parts or something or time? if its cost maybe we can all pitch bucks to someone to start doin R&D, someone who knows there stuff, certainly not me lol. i'd be willing to send some bucks, paypal or what ever u know. n e one interested? start a thread a new thread? thats if the mods allow it. i dont see why they wouldnt this person wouldnt be making money out of it. or that much n e way.

With the merging of the Zeta/Sigma platforms, does that make the new CTS a four-door Camaro?
No matter. As long as we can dip into the parts bins, I'm happy.
The part numbers I have so far:
Camaro SS Calipers, black with 'CHEVROLET brembo' lettering
92233188
92233189
These are threaded for 14mm mounting bolts and may require drilling out the mounting holes to fit the large diameter bolts (the CTS uses 12mm bolts)
G8 GXP Calipers, silver with "brembo" lettering
92221883
92221882
uses 12 mm bolts like the CTS-V calipers
(click to enlarge images)
from the measurements provided so far, these should just fit behind my 18" Z06 wheels without spacers. Sweet.

Any verification if hte camaro ss brembos are any different than the cts-v calipers? I wanted to upgrade my truck brakes to the cts-v calipers and either 13 or 14 inch rotors but if the camaro ss calipers are the same as the cts-v i'd get the camaro ones, they are cheaper.

i was wondering on exactly do you know the right thickness for the rotor.other than just waiting ang going on the peddle feel?also does the camaro offer them all the way around or just fronts?
#638
As far as I know nobody has tried them on a truck like mine yet. It sux cause my truck uses the shaft mount spindle. What i'm gonna do is machine a rotor down for a hub then custom make a bracket and modify the spindle for the camaro/cst=v calipers. Not sure what rotors i want to use yet cause since the spindle is shaft mounted the rotor offset is pretty big. I'll probably get a caliper first then figure out what rotor i'd need. I'll redrill a bolt pattern if I have too. Plus this is a good experiment too cause i'm gonna be doing brake mod on my firebird too, someday.

Does anyone have more exact measure of the CTS-V caliper or an engineering drawing?
I saw a few posts where someone had a tape measure laid beside one.
I'm looking into adapting these to my LS1 powered M3.
Sorry for the post jack, but having trouble finding these measurements.
