I have tried 245 20inch ET22 F tires but the handling became terrible, this time I'd like to find the best balance on 18inch track set up with ET35 or ET22 wheels.
Does anyone has ET35 on M3 has good handling?
The offset you want for the front is 18x9.5" et22.

handling is not an issue when it comes to offset. Autocross drivers would prefer the highest offset possible to keep their cars narrow for the slalom. Street drivers prefer wide setups for aesthetic/stance purposes. For the track, it should be a matter of function. Does your tire fit at et35 or et22? At et35 you will not be able to mount an r-compound without a spacer. ET22 does not require a spacer as the wheel is already the correct offset.

285/30/18 for the rear is shorter then preferred. 285/35/18 would be a better rear size in that width.

But a redline time attack E92 M3 did just fine on 265/35/18 on the 18x9.5" et35 wheels + spacer, and 18x10" wheels with 285/30/18 AD08's.
