Thanks, Chibana,
My younger brother suggested that I should've bought 19s. I explained that
1. No, I don't want to pulverize my kidneys or spend thousands for forged, lightweight 19s
2. Having a lowered suspension and stiffer, more compressed OEM shocks doesn't lend itself to larger wheels with smaller aspect ratios - the result of which is mentioned in #1.
I have noticed that sharpness of impacts is "buffered" with these 35% lighter wheels. Handling around road curves that are less than smooth is more reassuring, to say the least.
