Anyone Running Magnumforce Wilwood 4 piston brake kit?

... It stops like you wouldn't believe.
I never follow this statement. My 9" drums can skid the tires, so it too can stop as fast as any other brake system could. The issue is how fast do the brakes cool off between stops, when constantly using them, or do they fade when braking from ___ mph, fill in "90, 120, 160 ...". All I need is from 65 mph in my cars.
