Thanks! I got it to fit with almost no rubbing. Camber is at -2.6* with the BFG Rival 245/40/18x9 ET37 (ET42 with 5mm spacers). I have about 1.5mm clearance between the strut and the sidewall.
In the air, the only rubbing is on the passenger's side with the wheel at full lock to the right. It slightly rubs part of the underbelly tray. Didn't notice it when the car was lowered, and is fine on the street. First autocross with this setup is next weekend but I think I should be fine with no rubbing!
