Yeah, the 18x11 +45 is the limit of what I could do with stock available front camber and a roll w/ slight pull up front for 295s -315s.

At 25.5" ride height that is front -2.5 camber which is a lot for the street, good for the track and not enough for autox.

Rear I had at minimum camber and a lip partially rolled, so could do it with camber and no roll.

At 25.5" ride height that is rear -1.4 camber.

You dont want tires that stick out past the body at the bottom, it tears up your paint (hence my kydex mudflaps).

I would do at most the 18x10 +50 and 285/30-18 with minimal camber and factory mudflaps for a street FD with nice paint and no trips to track planned.
