Just doesn't look great imo

the track pack's cast 18" 398's w/MPSS(very light tires) are lighter than 442 or 403 19's but i don't consider it light.
aftermarket forged and rotary forged 18's/19's in 8.5"-9.5" widths can be as light as 18-20lbs per wheel. the best & lightest street performance tires are MPSS, MPS4S, Conti ECSport, Conti SC6. with the right combination it is possible to shed 10lbs of wheel/tire weight at each corner.
of course, in most cases cutting weight is not cheap...
