Looking for "Bang for my Bucks" rear disc brake, 2 piston to replace stock WS6 on my 88 GTA. Direct bolt on.

any good suggestions?

Thanks

Baer makes a kit like that, as do several others.

Question is if you need the emergency brake and what sized wheels and tire do you run/will run?

 

Factory 89-95 rear discs are single piston and not sexy, but cheap and easy to install from a donor car. They will handle anything you can throw at them for braking, unless, you planning on running endurance roadraces.

 

Yes its stock 4 wheel disc now. I need the EBrake and will continue running the GTA stock rims.
I just wanted to upgrade a bit from the single caliper.

 

The rear LS calipers are also single piston with an internal parking brake. As I understand, a conservative approach should be made when switching to larger calipers and rotors. When braking weight moves toward the front requiring the front brakes to do more work than the rear. So theoretically with the same size rotor and caliper the rear would lock up first which is what you don't want. You can add an adjustable proportioning valve but depending on the size of the fronts to the rears it may not be enough. And we have no abs to help us. Our cars with single piston sliding rear calipers are ok because most Thirdgen with driver only weigh 3200-3400 pounds compared to the newer sports cars weighing in at 4000 pounds with driver
