Does anyone know the rotor offset difference between the F-body and Vettes?
Nevermind, I re-read the first page and found that the offset difference is 6.3mm(1/4").
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 caliper is threaded for larger bolts which requires drilling out your spindles. Other than that, there does not appear to be a difference, other than appearance.
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 figured out the bracket for the cts-v Rear brakes. I just need to find the rotors with the E-brake in them. Does anyone know a place that sell custom rotors?

I'm guessing the stock 12" vented rotor is too small?? It would be ideal to keep the stock rear rotors and use CTS-V rear calipers, you don't need much more than 12" in the rear anyway.

Not that have the small drum built in.
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.

100% understood!
Ill stay posted on the camaro SS and GXP rotor test fit.
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.
Does anyone know if the G8 GXP calipers are the same as the CTS-v calipers as far as doing the swap with the z06 rotors? ie: just need washers to for either one or is there something else different about them?
