How has your ride quality changed since going up in rim and tire size? Please list your size rims and tires and if any other mods were done such as lowering.

 

my tein s-techs kept the ride very close to stock and more stable at high speeds. when i put on my volks (see sig), the ride actually felt a little less rough but more bouncy when going over bumps.

 

On my sedan, I went to a Volk CE29N 18x8.5, Yokohama AVS db S2 245/40R18 setup. With the stock sports suspension, the ride was hardly changed - really couldn't notice much of a difference. When I switched to HKS Hipermax LS coilovers for a minor drop, the ride change was noticeably more stiff / bumpy. Not untolerable, just a noticeable change.
