If you have camber plates and are able to dial in at least -2.5 degrees of camber, you can actually run the 255/35/18 tire with the 18x9.0" ET31 front wheel. This is our recommended track setup for the fronts, with a 275/35/18 rear with a 18x10" rear.

The trackability of the setup will depend on rideheight and springrates you're running. With adjustable coilovers its definitely trackable with some camber in the front or especially if you're willing to adjust height for track day. I don't think Apex suggests the 245/40/18 because of sidewall height in most applications, but a 255/35/18 would be less sidewall and a little bigger contact patch depending what your priorities are...
Awesome feedback, thanks for your input!
