I'm going to rebuild my front brakes, new lines, rotors, pads, bearings. My question is, the guy at autozone asked me if I had the Performance package. To tell you the truth I really don't know. I have a formula with the WS6, but I still have rear drums. How can I tell if I have this package???

Stock except for K&N, Flowmasters, Centerforce Clutch, MSD 8.5, and Accel Cap and Rotor. Much more to come.

 

By performance package they mean if you have the calipers with dual pistions. Regular is the calipers with the single big piston in the middle. The one with dual pistions I guess they consider perfomance package or commonly refered to as the 1LE package. To find out take a look at your caliper and see how many pistons it has. Also if you have the performance package your RPO codes in your glove box should have the 1LE code unless someone modified it on you.
