I'm considering going with an 18" summer wheel setup (summer lasts 10 months in my part of Texas), for better straight line grip, weight and cost vs 20". Anyone running 18x11's in the back with 315s? I was thinking these:

18x11 +43 with 5mm spacer on 315/35's DR's
18x8 +27 on 245/50's

I have the standard 4 piston Brembo setup and have seen that a setup similar to the one above works on the 5th Gen ZL1 (my main concern is brakes).

According to this offset calculator: https://tiresize.com/wheel-offset-calculator/

With the spacer, rear wheels and tires shouldn't be any closer on the lower inside (where the problem area of wiring harness is).

Thoughts on sizing? Anyone have something similar?

I'm running 315/30-18 on 18x11+43. Fits great in the rear.

I'm running the same in front, but with 20mm spacers for an effective offset of +23. (Requires MCS offset struts to fit 18x11" in front)
