What is the best combo??? I want to lower my car but i don't want to feel all the bumps and what not. I still want a comfy ride but if reduced alittle it's fine. I rode in a an IS300 the other day it has Eibach Prokits and 17"rims. Why is that car so smooth. When I ride in my max it's still hella bumpy. Shouldn't it be more comfy with the stock springs? What should i get? I also want to race with them...
