Grand prix gxp is a 12inch, fbody is 12inch, a 04 plus gp is almost 12 inch, 06plus impala are 12inch..lots have them.

you dont HAVE too. you can use a sleeve thats 12mm id and 14mm OD to make it work.

Wbodys l have same bolt pattern and fbody rotors will work as well even though bolt pattern is dofferent....brake motive on ebay has drilled and slotted for under 100bucKS shipped

brakes are about the easiest thing to work on every, but if your lost at installation already, you dont know what your doing to the fullest, do you?

rule of thumb here, if you take calipers from a car, use it rotors and pads, nothing else. theres is no mix matching of this part and this part. unless you want to crash and die......

heres a how to for f bodys, pics and parts list too. http://www.regalgs.org/topic/54303-f...brake-upgrade/


the imp or montie brakes replaces the stock crap too. only those just bolt on and dont need a sleeve or the bracket drilled and taped.

posted a damn how to. has everything you need to know about installing f body brakes. has the part # for the sleeve, and where to order them from.

you need a fishing pole now, you've been fed two meals so far.

Really?

everything you want to know and are afraid to ask is there... Yeah, 30 pages, but you'll get the drift on the first few... Give it a shot, read up a little bit.

for the record, the Fbody upgrade is a huge difference. RockAuto has powder coated Fbody calipers for $120 per pair, just a little over JY price, but they're rebuilt and powder coated, so worth it IMO. Then I'd settle for no less than R1 Concepts rotors : )

good of luck and have fun!

I run stock brake lines no issues..just need to bend bracket so they reach

still need to bent the bracket. and theres a pic of it. and how to do it. only difference is you need that sleeve to center the f body bracket bolt. other then that the job is the same.

Run brake motives on 3 of my wbodies...no issues at all with them.
