I went to get new rotors, and they asked me if I have the performance package. How do I know. It is a 91 Camaro RS it had the 305 V8. But I have no Idea if it has the performance package. How can I find out?

 

The performance package (1LE) will have 11.7 inch rotors with alum calipers. The regular rotors are 10.5 inches and have iron calipers. The following link will show you the performance package for both front and rear:

Ok, does the performance package have dual piston callipers? because mine are single piston

 

Yes.

 

sorry to bring this one back from the dead, and/or beat a dead horse, but does the dual piston caliper distinction work for the '84 pontiacs too?

 

A stock 84 will have single piston iron calipers.

what about an 84 with the performance package?

 

Nope. The 1LE package didn't arrive until the late 80's.

weird. my brake rotor application book at work shows rotor options for with and without performance for an 84. guess i'll just go with without.

 

Parts books are like that, some data entry freak got overzealous and listed things in the wrong places. Most thirdgens have the standard brakes, but those books wont tell you that.

 

yup just late 80's and dule pistons but the only thing thats not a z or iroc to get them might have been a B4C inerceptor package(cop car)
