my "break in" procedure was very similar to the one in that write up..... but i got my car with 10k miles on it. 1st and 2nd gear hard acceleration runs almost every day, putting in the clutch and letting it coast back down at the top of 2nd gear. (also served as some pretty good practice for drag racing
)
I really do feel like the car is faster now than when i first modded it. my best indicator is that back then, from a roll, it wouldn't spin the stock 235 pirelli's to save its life (without dumping the clutch). now, i have bigger 255 nitto 555's on it, and from a roll traction isn't very consistent, it'll break them loose pretty easily even on grippy roads in 90 degree heat.
