Hi everyone. I am about to start working on my 82 Trans Am project car. So I'm sure you'll see me on here a lot. Anyway, the question I have is: what is the best plan of attack to change my rear drums over to disks? I currently have a 3.27 LSD drum rear. Would it be easier to find a whole rear end that already has the disks? or is there some way to easily retrofit disks on my current rear end? I know I will have to change the master cylinder, but do I also have to change the proportioning valve? TIA

 

it would be easier to get a new rear end. YOu could probalby find one for $200-300 maybe even less if you look hard enough. You will have to change the proportioning valve. I suggest getting the adjustible kind. They only cost about $50 and are easy to put in. It will help alot.

 

4th gen Fbodies with V8s and 6 speeds have 3.42 posi disk rears. they are wider though

 

Start first with the technical articles section. There is an article on putting LS1 brakes in a third gen. This issue has come up so many times that there is all kinds of information available.

 

Ok, I'll check it out. Thanks

 

AndyZ28 is working on this very thing.

I have seen some pics - and the stuff is great.
All 1LE type rear disc setup that bolts on to drum rear brake cars. very slick. He should be releasing the stuff soon - and it will be a COMPLETE kit. Trust me - this will be worth it.

 

I got one of the very first kits Andy put together, and it IS definitely worth it!! Every bit!!

My braking is awesome now, and it included everything I needed!

Highly recommended!! I posted on the Review Board right after I put them on, check it out!

Hope this helps!

BTW, I'm putting together an 83 T/A that I can road race/SCCA F-stock or F-Modified (can't decide which right now!) and these brakes should fit the bill nicely!
