Thread: Used Drilled Slotted Rotors?

Going off my comparison of rotors for a 2003 Grand Prix and a 2004 Grand Prix on NAPA's website, it appears that I was correct in that 04+ cars have 12" front stock and 97-03 cars have 11" front stock (or 11.69" & 10.94" respectively -- whatever). However, bballa mentioned Monte Carlo rotors, so I checked into the stockers for a 2002 Monte Carlo, and they're listed at 11.94", which has me going . Also, the rear stockers for the 2003 Grand Prix and the 2002 Monte Carlo are both 10.94", but the rear stockers for 04+ Grand Prix' are 10.63"? This all just seems a little ridiculous to me. Please don't tell me that each variance in 10.x" and 11.x" has its own mounting bracket as well, because that would just be d*mn silly.

The 04+ Grand Prixs (exc GXP) have 11.6" rotors.

97-03s have 11" front and back or 10.9" is you want to be anal.. lol

and 16" rims will fit over rear GXP brakes.
and I run F-body front and GXP rear with no problems. It doesnt throw off the bias
