Thus, if the car comes in at about 3,700 lbs plus 150 lbs for me (with a stock engine), I believe I can be dyno re-classed into TTB or TTB*. Assuming that is true, do you believe the e90 M3 can be competitive with AST coilovers and Nitto NT-01s 255s in TTB* or Hoosier R6 265s in TTB)? Thank you in advance for your thoughts...
If you can actually do that, then yeah it could be competitive. But you know if you get reclassed (which is difficult to do anyway) and then seem to have an advantage over the other TTB competitors they may take away the leniency. I love the M3 for what it is, but I don't think it is a good TT car.
E46 M3 is still a pretty good TTB though.
