When i did some searches here, results shown for the N52 a square 235/40/17 is "the best", 245/40/17 if one desire more grip and for x-cross and serious track 255s all round on 17s.

245/35s are out of the question for me, no one makes a track day tire in Germany that size except Federals and their 595RS-RR which are not legal (unless you enter competition).
If you've some 128's putting down ~ 270 at the wheels....do you know the recipe for the mods? I think the highest dyno I've seen was barely knocking at 250.....around 248 I believe.

Aside from a supercharger, I would love to be able to see 270 to the wheels as it would make this car ridiculously fun!

Just wondering. I don't track my car, but didn't know if you guys that did were sitting on an "insider" secret.
