Agreed on the street use issue. Stock brakes are more than adequate by a long shot. They are VERY good. Just not quite up to the task of track use for a heavy footed kludge like me. By no means am I a hardcore tracker. I just like working on stuff.

A group of friends run their stock brakes on SCs and Carreras with R tires, with the downsides being cooked dust boots and some leaking calipers following some hard DE track days. I learned my lesson cooking brake pads that weren't up to the task of hard braking (Ferodo DS2500) on a somewhat heavy street tire equipped car like my '87. So I figured i'd forego the incremental attempts at solving my brake problems (pads, cooling, spendy fluid) by doing the whole shebang and be done with it.

Don't get me wrong. The right pads, cooling and fluid are certainly important. But additional thermal reserve of bigger rotors, pads is the best solution. Thus the pads, cooling, fluid can then make the brakes perform even better and last longer.
