Ive been trying to decide weather to get rid of or put some work in to my Grand Prix. I didn't care much for the car when I first got it, Mainly due to the sloppy suspension and braking and handling. At the same time I like the look and the as well as the decent amount of power that it has. sooo... I have decided to keep the car and upgrade what I don't like about it. First off are brakes: I have read on this forum that with F-body Brackets and rotors (05 Monte Carlo) You can accommodate C5 Calipers. I figure That set up would provide adequate stopping power. So my question is.. Would I need to upgrade my brake booster/master cylinder?

Any input would be aapreciated

Thanks
