For starters, the stock 18" setup is HEAVIER than the 220 setup, but lighter than ZCP. However, ZCP wheels are wider, with suspension slightly stiffer, BUT same tire sizes; which setup is better? Forged 18s lighter than 220s would be a better argument, but they still wouldn't be as good as 19s in every surface. Just look at every modern supercar, and none I remember has 18s ; there must be a reason.

Bottom line is for the OPs problem, he'd benefit the best with a forged set of 18s IMO. Good day gang.
I full agree here.... I saw significant performance increase at road atlanta with 19's over 18's. Same rubber, same day - back to back runs with 19's with slightly wider rubber. less sidewall means less tire squirm - simliar to having stiffer springs - less time wasted in transition.
