You are correct. The stock brakes won't last very long on the track. You'll burn them up pretty quickly.
For the road course, avoid the power booster. You'll get a lot of variance as the rpm's change, unless you use a large reservoir. Big brakes couple to a booster makes the brakes very difficult to modulate. The pedal becomes more like an On-Off switch. It will be almost impossible to modulate.
Dollar for dollar, it's tough to beat the Wilwood kits. Good quality and performance at a reasonable price. Replacement parts are easy to come by. Contact Gordon levy for a complete kit. And I do mean complete. The only thing not in the box was the safety wire.
