DCCD made little or no difference for me on track days, you'd have to be a severely talented driver to make the most out of such a small feature IMO, either that or a little delusional in believing that its helps you along to any great degree. Anyway, I'm not going to clutter up the guys thread with a proper reply challenging the fact that apparently an STi is the only choice for track work, I don't agree, so we'll just leave it at that.
Cheers,
