73 to 76 Dart Disc Brake Kits

I spent some time looking at the Wilwood website at their brakes. Their kits say for a 2800lb car. What other kits are available? I'm looking to save some weight over the stock rotors. I'm wanting to upgrade the 73 lbp brakes on my race car, Thanks Jeff

Added info: I have one of their kits on the front of my 68 Dart GTS that was originally equipped with 10' drums. That is where the 2800lbs come from.

Dig through the MoparAction backissues. They cover a bunch of them.

I bought some Aerospace Components vented rotors for my 3,500 lb cars but haven't had time to install them yet.
