W body

do the 2000+ impalas come stock with 12" rotors? and are you 100% sure the brackets will fit my car?

Yep!

Intrique, Impala, Grand Prix and Regal are all W-bodies from 1997 to 2003.

All W-bodies use the same knuckle and calipers, only difference is the caliper brackets and rotors.

Cheers,

so which ones if any came with stock 12inch rotors? or was it only offered as a performance package?

1997 Intriques and 2000+ Impalas.

Cheers,

hmmmm, im pretty sure the only Intrigues with stock 12 inch rotors were the ones with the Autobahn package, and they didnt make them in '97 btw...and mine is a 2000 and i dont have 12 inch rotors, at least im pretty dang sure i dont.

allright heres what ive found using a combination of all kinds of things, but mostly using gmpartsdirect, the caliper mounting brackets and the accessories that go with them could be found on:

1994-1999 Cadillac DeVile
1998-2003 Cadillac SeVille
2000-2003 Chevly Impala
2000-2003 Chevy Monte Carlo

the mounting bracket part # is 18029829

as for the 12 inch rotors..they can be found on MANY different cars.

im too lazy to type out all the various cars with the 12 inch rotors..the part # for the rotor itself is 18060640 in case anyone is curious..

if anyone has any leads on a junker with those mounting brackets id appreciate it...because if i find a car with the brackets, the rotors should be there too... thanks for the help again guys

Sorry, 98 Intrique and it was only with the Autobahn option. 12" brakes are standard on the 2000+ Impala.

Cheers,
