Did the SS Mustang have to run drum rears? In American Sedan, upgrading to disks (large ones all around) is allowed. My brakes are stone stock except for the steel pin bushings and the braided lines, and I run Hawk blues in front and blacks out back. The funny thing is that when the rears go away, the only way you can tell is that the pedal travel has gotten longer and there's noise. :) The rears last several hundred laps but the fronts last about 150. Before I cut out the splash shields and discovered I needed to grind off a bit of the edges of the inside pad, it wasn't unusual to lose the fronts after 40 laps. The inside pad would expand and get "caught" in the caliper so that the piston was just bending the middle of that pad toward the rotor. When we changed out the rearend this weekend, I was too tired to deal with putting on the good shoes so we ran the rest of the weekend with the old street shoes that were on it, and didn't have any problems with them. Heartland Park is really bad on brakes when you run the 2.5 mile layout. Turn One is a terribly slow right-hander at the end of the longest straight. I hit 135 mph for the first time on that straight on Friday, thanks to a nice tailwind. My usual speed there is 125-130. The brakes cool nicely on that straight, but get very heat-soaked at the end of it. They're also used pretty hard for 5 and 6, and I've had them unavailable for 8, which can be fun. <g> Also finally got to regularly use the rev-limiter. With 3.55 gearing, you exit turn 5 in 2nd gear and quickly shift to 3rd for the downhill going into 6. With the 3.27, the shifting would come too late, so I went ahead and left it in 2nd and just let the rev-limiter do its thing, which it did beautifully. I've tried lapping that course without brakes except for Turn 1, and it's not only possible, but only about 4-5 seconds slower. Probably 7 or 8 if you don't use them for 1. Bob ... You know you're a racer when you refer to the first intersection near your house as "Turn One".
