My 335 had stock suspension, stock brakes, and crappy Falken FK452, and really seemed to struggle at Willow Springs. I'm sure if you swapped out the brakes and suspension it would be pretty good. The other problem I had was overheating. You'll need an aftermarket oil cooler if you are going to blast at the track. Other than that, I liked the 335. To me, it was a modern day Supra and I love turbos. Ultimately, I just preferred a track ready car.
That said, my M3 has now been sold. I had the itch for more horsepower and am either headed towards a GTR or 997 Turbo.
Well said. Good job and happy hunting for your new toy!
