Brake swap

[dleroy]

So I recently got a set of grand prix gxp rims for my 2000 SLE and I immediately realized how small my rotors were and decided to up my rotor size but wanted to swap some bigger calipers on and wondered which cars I could swap from and what my best choice is

Direct swap would be the GXP brake set up. Otherwise, most other calipers require some custom effort like new brackets.

actually there are many options for the front. The rear you only have one Option and that is the Bonneville GXP Rear

Front options

Bonneville GXP
Grand Prix GXP
06+ Deville/Lucerne
06+ Impala/Lacrosse
4 Piston CTS-V Brembo
6 Piston CTS -V Brembo
99-02 F Body Brakes

So the 2000 F-body would work? I can get a good set of Camero SS
caliper and rotors for cheap. Would they be as good as the GXP brakes?

[MattStrike]

F-body rotors are 11.9" diameter, the GXP are 12.8", so GXP is going to be better than the F-body, all are going to be better than stock.
Best would be the CTS-V setup, 14" rotors. But won't fit under anything less than 18" wheels.

The F-body setup uses the same as OE rotors, just upgrades to a dual-piston caliper...

I forget that '00+ SSEi/SLE got the 11.9" rotor as well.
