I've been asked several times over the past few months to develop a rear 4 piston conversion while retaining the factory drum parking brake. I have finally figured out how to do it and would like some feedback as to the actual demand for such a system.

The system would use a 12" rear rotor and small 4 pot caliper. Obviously you would need to have a front brake as large in order to maintain brake balance.

I figure I can sell the system for approx $825, less if I received enough orders to allow me to purchase the rotors in quantity.

Let me if you have any interest. thanks
