hey
no you dont need new shocks....straight away. but the oem shocks will wear out sooner and you'll need to get them revalved ot get new ones. i have eibach springs and stock shocks at the moment - no problem....but i can feel the shocks getting a little softer, making the car a little bouncier...but not much at all. certainly nothing to complain about.
having said that, i will be getting mine revalved shortly. speaking of that, does anyone know the spring rate of the eibach springs?
