Does anybody know the weight savings for swapping to a rear disc brake kit over a stock drum brake setup? I'm looking at a wilwood dynalite kit for my new rear axle.

The stock 10" drums weigh about 36 pounds complete. What is the shipping weight of the aftermarket stuff ?

I went from 11 X 2" to a Wilwood with the Explorer type internal parking brake and lost 16 pounds. Did you use the street or drag setup on these? The rotors are a lot thinner on the darg kits.
