MPP set the Laguna Seca lap record with an 18x10.5 square setup. Adjusting the camber (which requires aftermarket upper arms) doesn't change the space to the knuckle but it does help you to clear the fenders.Probably can’t put too much camber in the front because it’s too close to the knuckle. 18x10.5 ET30 is gonna be show car setup and definitely not a good idea for track or sometime even daily driving... most of the people run this setup when they have air suspension install.
I've got 18x9.5 ET39 with 265/40 tires with the regular brakes and I wouldn't want less offset than that on the front since they already stick out a few mm beyond the fenders at stock ride height.
