Shock absorber bump stops
I'm installing Bilstein HDs with H&R Green springs. H&R's directions with the springs say that 3/4" must be trimmed from the rubber bump stops. They do not say whether to trim from the top or the bottom of the bump stop. Anyone know?
Cautionary note: if you're doing this same upgrade anytime soon, I strongly suggest you buy new bump stops in advance ($15-$20 each); my local Porsche dealer does not keep them in stock. Luckily, an online supplier had them and is FedExing them overnight. My bump stops were original judging from them having virtually turned to orange dust when removed, so trimming them was moot.

Before you order and install - Please search on this forum about the need for bump stops with the Bilsteins. At the moment I do not recall which - but I believe that the Fronts have an internal bump stop and the external oem bump stop is not required (nor desireable).

Thanks, DWS964. I just called Bilstein and talked to one of their technicians. He confirms that Bilstein HDs have an internal bump stop and don't then need the rubber bump stops.
