Dedicated Rotors for Track Use?

If you're gonna do that, do yourself a favor and buy caliper studs from tarrett/rennline. With that many caliper removals, you run a pretty good risk of stripping the holes in the uprights.

I run pfc 08s full time and they are just fine.

Overkill. Swap pads if you must but I run race pads all the time. Yes they squeal when cold, don't care.

I agree. I have street and track pad set, which I switch, but I would not switch rotors. In the end a set of rotors doesn't last that long running hard high temp range brake pads. So as part of my winter prep work I replace rotors.

I have drawn up some brake studs and they are on the machining list. I specced them out of 416 stainless steel.

Is the street wear insignificant enough that you don’t mind premature wearing out of the track pad? They cost quite a bit more than the street pad. Or do you like the increased performance on the street as well?

Street wear with a race pad is approaching zero. Race pads also provide the best possible braking performance when they are good and hot, so when cold on the street you give up some of the performance and feel. They still have no problem going into ABS under hard braking when cold so they stop the car just fine.

Over 12 years and 150+ track days I typically get 6000 mi and 20 track days on a set of front pads. Probably 18k miles and 60 track days on a good set of front rotors. I see no benefit or cost savings at all by swapping out pads or rotors between uses other than eliminating brake squeal when cold.

Track tires are another matter.
