looking for a bolt on brake kit for 79 4wd trans am
the cars has 4 wheel disc and is all brand new stuff but is not strong enough to hold the car with slicks i cannot stall it up at all it will just push through the brakes but stops fine on the big end  i would like a 2-4 piston calipers all around maybe some bigger rotors not a huge fan of the willwood set up but i need something any help would be great thanks.  

Whew, for a minute I thought you meant 4 wheel DRIVE!! A cheap front disc uprade is to use the spindles from a 79-up Full size wagon with 12" front rotor and the later 1LE rotors(around 89-92), the later rotors have the same 5 on 4.75" bolt pattern and use the same bearings as your stock rotors, but they will have metric studs which you may want to swap for Imperial threads. This swap uses the same pads and calipers that you already have, thae advantage is in the greater leverage provided by the 12" rotor. If bolt pattern isn't a concern, the wagon rotors will work fine but they are a 5 on 5" pattern. Be sure to get the 12" dust shields as well. If this isn't enough I'm sure there are several kits available, PST has some nice complete upgrade kits. Maybe it's time for a transbrake!
