Thread: twelve inch brake upgrade

I was able to find the brackets from a 97 park avenue at the local pick a part for 5 bucks each. My question is this, should I get rotors from one of those cars as well? or what rotors do I need to get?

According to rockauto, the 97 park avanue uses the same rotors as the 97-03 gtp and the 04-05 impala ss... so you see my confusion?

What about the Fbody brakes? I was also looking up which years Fbody fit the GP. Will any 93-02 Fbody (trans am / camaro) brakes will work?

I have the brackets rockauto said i needed. I am just confused by the rockauto site saying the 03 monte carlo ss uses the same rotors as the 97-03 gtp. Here is the list they give:

Just get them for an 05 monte carlo.

For the f body brakes, any 98-02 camaro, firebird

this will fit with stock mags? but if you were getting bigger brakes wouldnt you need new calipers too?

anyone know if these rims are compatible. im guessing they are.

2005 Pontiac Grand Prix 16" Factory Original OEM Wheel Rim 6587

stock 16" wheels will be ok with the 12" upgrade. i just did mine this weekend and they fit fine under my abs wheels.

well...if 16s work...why wouldnt 17s?

So you need the FBody rotors calipers and pads for the 12" upgrade to work properly? Is there anything else that you guys would recommend doing after upgrading to these?

so what is the average cost for you guys doing this 12'' brake upgrade? and did u guys also modify the rear brakes? or does the parking brake screw things up to do so?

How did you do your upgrade bio?
