My experience from this weekend. Ran a two-day HPDE with the local P-car club...
Track:
Setup:
* Agressive Alignment (max negative camber in the front with pins pulled, zero toe)
* Enkei NT03-M Lightweight Wheels (18x8.5 front / 18x10 rear)
* Nitto NT-01 R-Comp Tires (235/40-18 front / 275/35-18 rear)
* Ferrodo DS2500 brake pads front / Axxis ULT rear (I keep this combo in for street and track use)
* Super Blue brake fluid
* Everything else stock
Outcome:
Advanced two run groups to solo and was working the car hard. Only things passing me were the GT2s and 3s. Ten to fifteen laps at a time with lots of brake usage including hard stops from 100-130 to 30-50 every lap. Experienced no fade. Brakes worked beautifully. At the end of the day, the wheels were almost black with dust and the rotors were a nice bluish grey color (and also worn...there's definitely more dovetail along the edge of the rotor than there was before). So I really don't think it's quite fair or valid to say that "the brakes suck and are only good for highway driving".
