Out of these options who has used them and what were your thoughts
1. Willwood BP 40
2. Ferodo 2500
3. Hawk DT-30
4. Willwoood Poly Matrix A
I have tried the Willwood BP 30 and Poly Matrix A, liked the BP 30 when I was running the stock brakes with a vacuum booster. Since I switched to the Willwood Dual Master set-up I find the Poly Matrix A have more bite when they are cold and seem to bite better with less pedal pressure than the BP 30's required. I also noticed the rotor wear with the Poly Matrix A is less.
I still would like to find a pad with a bit more cold bite and similar performance characteristics when Smoking Hot!!!
