I am new to the w-body platform and I just got an 06 GT. I am wondering if there are any brake conversion kits to put the brakes from a GXP or a COMPG car on my car?
Also I have been reading about the supercharger pulleys. What all would I need to put a smaller supercharger pulley on my car? Do I need computer reprogramming or intake or exhaust???

I really have no idea I am new and spent the last 4 years working on my sunfire.

Thanks for any help
