my car still has stock suspension. the ride is ok, stiffer bc of the lower profile sidewalls, i can feel the pot holes more. it is a trade off, looks for ride comfort, but i would still get 20's again bc i like the way they look. the only thing i would change w/ these rims would be getting the 275/35 all around. i saw an article in 5.0 magazine w/ the CS8 mustang, just like the CS6, the rims were razors w/ 275/35 20 all around. thats what made me get the razors.
