You got it sir. PM has been sent.

Is there a way to calculate reverse (flat-lip) depth for Forgeline GT3C and/or ZX3P? I've narrowed down my choice to these two. Wondering which I'll get a deeper lip on. And what the difference is as I go up in width. Is it strictly linear? (aka if I have a 1 inch lip on a 20x9 and go to a 20x9.5 is the lip going to be 1.5 inch) Any issue with using run-flats on Forgeline wheels? (I'm guessing not, but, never hurts to double check these things.)

Think of going ZL1 setup (285/35R20 Front and 305/35R20 Rear)
Opinions on what rim widths to go with?
I just want to avoid rubbing issues at all costs.
Suspension setup is Eibach Pro-kit (1 inch drop), with Bilstein B6 front struts/rear shocks, Hotchkis sways and chassis max brace.

The lip size has a few factors

Wheel design
X factor
width and size

Lip size is slightly linear but it also matters on offset for instance you can do a 12" wheel but the lip may not be bigger then a 11" wheel because of the high offset needed to fit the vehicle.

So in this case Run flats are fine and I would do the 20x10/11 combination for you with no rubbing forseen.
