The Bilstein struts are the best available for our car IMO. Quality and craftsmanship are top notch and the performance has been excellent.
Yes even better then Koni's. (don't even bother trying to use the "adjustability" part either)
Softening the struts for cruisin' may be a nice perk (whoop-de-do IMO), but actually "tuning" the proper valving for all four corners is just NEVER going to happen (I.E. pipe dream) without $$$$ for other calibration and multi-scale equipment.
Now don't get me wrong at all. I'm not saying Koni's are bad struts. In fact I think they are high quality units, just not better then the Bilstein Sprintline's for performance and quality.
Seems some magazines and other reports indicate that as well as the 2 I have read recommend the Sprintline's. (IIRC someone posted a link to one of them in an older Bilstein thread)
