Which do you think effects right quality more...

[1] H&R Lowering Springs

[2] Konig Tantrum 18x8.5

[3] Kuhmo ECSTA Supra 712

 

all those things contribute to a sportier suspension.
You want luxury stick with OEM suspension.

 

Kuhmos. Kuhmos are crap.

 

Actually, I find the H&R and Tokicos to give a better ride than stock.

 

Harder low profile tires will return small back to you then highprofile tires. Stiffer spings will return the bigger bumps back.

With my 18x40s I could feel every little bump, but the big bumps were still like stock, but ofcourse still harder. With the JICs it was a lot harder for small and big bumps. With the JICs and the stock wheels and tires the little bumps felt just like the stock suspension but I can still feel the big bumps because of the JICs

I hope that makes sense.
