87-91 ONLY....[/quote]

Although if you Call they can get Slotted and drilled front and rear for 184.99 but that is the Eline series and not as high quality as the premium series..

Here is the Rotor Diameter (OEM)

11.72" GXP rotors
11.93" seville rotors. 12.60 STS

12.72" Diameter Rotor are the fronts GXP
12.72" for the STS fronts

would a difference of that much make or break it ?

I think if the price is right I might just get my own set up MADE.... working on it right now looking at different things trying to cross over the Seville to the Bonneville.

Edit I just got off the phone with a guy at www.revolutionbrake.com gave him the Numbers I have. We spoke at length about sizes and complete kits pretty much both scratching our heads. The call ended with the the information he had being sent to engineering I guess they have a better understanding on what crosses over the what. I should be getting a call back either tonight or tomorrow morning.

Ok as of right now I'm waiting for a email from Kevin at revolution with all the specs and sizes BUT we have found that the STS base non big brake kit will bolt up

Jim,

I would be checking and double checking anything I purchased from them. When I called to ask about Rotors for the GXP I was quoted the wrong diameters for the Front and the rears as well but they had a kit ? or maybe the guy I talked to had no idea I finally talked to Kevin at revolution and we are at this point working on something for the GXP after we confirmed my suspicions that the Cadillac fronts were the same.
