The brakes that came with the car were fine on most roads but one day coming down to the desert from Julian CA they got hot enough that the pad material melted to the rotors in huge streaks. Ordered some big brakes from Master Power Brakes immediately and Wilwood remote reservoir masters. Made the trip several times after that with no issues. I also think I will run out of rpms with the shorter gearing to make it to 180mph (yeah, rpms, thats the ticket). With the old 2.73 rear end I was at 4400rpm at 145mph and still pulling hard. I can't imagine 180 in that car without a splitter or dive planes/vortex generators. It will cruise comfortably up to about 135. Unless you are 6'6", then the bugs really hurt.
