Reply to "Installing new brake rotors F&R"

What's a two-stage brake booster? Anybody know how they perform, before and after the upgrade?

I'm putting in residual pressure valves when the project gets going. They are 2 psi Wilwood units and I expect quicker pedal response and shorter pedal travel. It's not because the master cylinder is below the calipers. 2 psi is not enough to cause the brake pads to drag at all and cause any loss of horsepower or heat build up. Right? Please tell me now, because I don't have to put them in, but the idea seems good, they are $20 each times two (cheap!), and easy to install while the entire brake system is being upgraded. Seems like it would also help during racing applications, where sustained high centrifical force could cause cause lower pressures to accumulate on one side or the rear brakes. But no one's suffered problems adding 2 psi residual pressure valves, have you? Please educate me.

It's a stock body with stock wheels. I want Halibrand's like R McCall has, so I'll be measuring soon too. What wheel offsets are you specifying, Jim?

NASCAR is using 6-piston calipers, but those guys don't use their brakes going round and round, just when they pit. So the bigger brakes must be mainly for hauling down the car from high speed on a short distance. Is this about right? In other words, why does NASCAR use 6 piston brakes?

I am concerned about two things. Somebody pulling in front of me when I'm driving in town. I will also occasionally be on the track coming down the front strightaway into the hair-pin turn. Those are the reasons for the brake project.

Any comments on experiences with the Wilwood Polymatrix brake pad compound compared to the tan semi-metallic brake pads will be appreciated also.

I guess there's a lot I don't know, but it's cool learning. Thanks.
