I've been reading quite a few posts regarding limited traction. Today I got on the throttle a bit and mine wont spin the tires in 1st or 2nd if you just mat it unless you're around 10mph in 1st and stomp on it or side step the clutch. Power shifting from 1st to 2nd gave a tiny bit of tires spin but nothing significant. Do the 255s on the Brembo package really provide that much more traction than the rest? I'm amazed by the rear grip; either that or my car is down on power from everybody elses.
