How can I tell if I have these brakes? My car is a 87 Iroc original 305 5-speed car with disc brakes all around. I do have the ls1 rear set up already. But I would like to know how you might be able to tell if the fronts are 1LE. Did these only come on 350 cars?

They only came on 1LE cars, and B4C's.

If the caliper is cast iron, they're standard brakes. If it's aluminum with two pistons, it's 1LE.

Pic in my vbGarge (lower left), should you wish to see a 1LE, front and rear, system.

Hey Thanks guys! So cast iron is standard, and aluminum is 1LE. I will have to check on this tonight. I don't know what a Vbgarage is, but I would like to see this setup. I appreciate the fast response, and thanks again!

Under my name at the bottom. Little roof with a car under it.
