a guy parting a car locally has the performance brake option on his rear end.. i have the stock disc option on mine. i was wondering, do i need just the bracket to make those calipers fit? i am of understanding that the rotors and pads are different so im excluding those from the question.

 

pbr's? aluminum, 89-97 style?

 

I assume you're talking about the 89-92 PBR's.

Yes, you need the backing plates (along with all the other components, to include the combination valve).

Here's the how-to:

They are fron an 89 gta disc brake rear. The calipers look like this http://m.advanceautoparts.com/mt/sho...461%7CL3*15684

Idk which is pbr's and stuff like that.. Im a noob to this subject.. Is it worth upgrading? The guy wants 150 for the brackets and calipers

 

Those are PBR's.

The set-up would be from a 9-bolt in 89, so if you have a 10-bolt, the backing plates won't fit (though the correct plates can be purchased). If your car is equipped with drums, you'll need to modify the axle flanges or buy a hassle-free kit from the following site:

The upgrade is worthwhile.

You'll have to pull the axles:
