Every time i drive my s2k on a racetrack i wish i had a little lower/stiffer suspension. Then i think of all the public roads i've driven on with the car (bumpy roads, country roads, steep country roads leading to a beach/lake, etc) and immediately i'm happy again with my stock suspension/ride height.
PS: Killed my differential two days ago on the track... taking every turn sideways + stock diff = bad idea (but lots of fun). :P
