From what I have been told as long as the bore size is the same the pressure in the system should be the same. With that being said as long as the caliper will bolt to the mc knuckle it should work fine. The mc uses a 1" bore as well

The m/c's are diff GM part numbers but use the same cyl res, so Im not sure what the difference is internally on the two.

Hey GXP25, was your idea of using front GXP brakes on rear was so they matched?
Yes pretty much.

Heres some pics were I modified the mount area on spindle and the area in tape shows where inside ribs need 1/8 machined off if you dont machine down edge of rotor for rubbing issue.And final pic shows why I cant use the 14" Z06 rotor,no room for custom bracket!Even if I move caliper down to use bracket it would hit control arm.So right now Im stuck w/ 13" rotor w/ Z06 caliper

For some reason the pics came from my phone and I cant get them larger.

The only other thing I forgot about was the brake line to caliper but I dont see that being a prob if they are changed to braided lines

That's what I meant. Why not just try and make the CTS V Brembo caliper fit and use a C6 Z51 rotor which I believe it 13.4

As cool as this is i dont see the point. GXP already have 12.7" rotors. and the extra clamping force would be nice but. Not for this price. But im glad we now know we can do it. not trying to flame or anything.

That why I asked about swapping out the rears with a set of our fronts (yes I know the fronts do most of the stopping).

Well this swap started off as goin w/ the 14" rotor but b/c of caliper mounting it wont work w/ custom brackets for calipers.So since I was messing round w/ this I just figured Id try and make something work at least.

Using fronts on the back prob not gonna work b/c of master cyl/prop pressure but Im not sure,would be cool to match though.
