Looking for a track day setup not a daily.
Thanks for the post! For your setup we recommend the following:

Front & Rear: 18x8.5" ET45 with 235/40-18 tires
  • 5mm front spacers likely required for to clear KW suspension.
  • 245/35-18 tires can fit with 5mm front spacers and approximately -1.5 degrees of camber or more. Larger front spacers may be required for certain aftermarket suspensions, see below.
  • 255/35-18 tires can fit with 5mm front spacers and approximately -2.5 degrees of camber or more. Larger front spacers may be required for certain aftermarket suspensions, see below.

Keep in mind that since you are using the M3 control arms, your negative camber is achieved by pushing the bottom of the strut outwards, rather than bringing the top inwards, so this may reduce your fender to tire clearance as a result. The 235/40-18 tires should still clear up front though without any rubbing.
