Do many tracks allow the use of rear disc brake swaps in pure stock? The rules for lebanon valley don't mention it at all. What swap would work on a second camaro/firebird or metric?thanks!

Weld-on brackets that accept 74- 78 Camaro
calipers along with rear discs from 88-92
Firebird GTA (firebird or Trans Am are
different). Discs are about $80.00 each and
can be had from most local parts stores
along with the calipers. These pieces will
work on Metric or 68-72 Chevelle rearends.

A cheaper way of making rear disc brakes on a GM 10 bolt is to find you a Cadillac front wheel drive with rear disc. Get the rear caliper bracket, rotors, and the front calipers. You have to cut 16th of an inch off the hub of the axle so the rotor will slide over it. Other than that bolt on and go.

we did what pickel described and worked like a champ.
Ive since found that camaro rotors from a 1LE equiped car will work also, you need to use an aftermarket caliper bracket and just watch your spacing, the rotors are larger and will be close to stock wheels. it will fit. these rotors have a larger hat size so no maching. they cost like $30 each, i can look up the part number if needed. 1 other problem we ran into was a hard brake pedal that wouldnt stay. I later traced the problem to brake pad wear. when the pedal was released it pulled all the fluid from the rear pistons forcing the caliper to travel that much further, so either keep good pads on the car, or invest in a wilwood 2lb preasure take up valve.$15..
rear disks are easier to maintain and safer.
We ran them at FONDA in the SS class, and argued thier use. it will hold a broken axle on the car, especially in a stock type class where alot of cars still have the c-clip type rears in them. the techs saw our point and now alot of guys are using them..
another advantage is when a leaky rear seal can cause a drum brake to start grabbing, a disk wont even get see the fluid.
I will get the part numbers for anyone who requests it.

For you LB Vally boys, well be at your swap meet selling parts, we can talk then if your going...
