How much stiffer will the LSS make the car? does anyone know? i cant decide whether to opt for it. will the ride really suffer alot for regular day to day driving? how does it compare with the euro spec cars that we've driven in our dealers? basically what im worried about is going through a pot hole, i kind of do not want the car to rattle and feel like it is falling apart becuase i had that exdperience with teh euro spec elise. will this happen with the us spec?
