( as in, theres less of a hang when the car is in the air/jacked up)
If you note in the photo I marked the strut with a permanent marker where the bump stop hits it. So I will check in a few days after some driving if the marker is still visible. ( it quite easy to push the strut cover up so I will see if the marker has been rubber off which will be a clear sign if the car is hitting the stop already.
Thanks

You can see my post here on how to remove the shock from the front strut if you need to chop your front bump stops. Bilstein might use "red" loctite on the nut/shock piston so you might need a torch to heat it up to get those off (using an impact is fine on the nut). I use "blue" loctite when reassembling.
From your droop comments it sounds like your shock body is shorter than mine (makes sense so it doesn't bottom out in the bottom of the strut body with lower springs), but that shouldn't do anything for the exposed end (top mount side) of the shock since that's determined by the spring.
Actually in my picture in the linked post you can see my original Bilstein bump stop torn (outer section tore from inner core) |
I've checked the bumps stops last night.
Rears no issue whatsoever!
Fronts: when car is loaded, ( as in sitting on its wheels) the dampers compress and leaving about half an inch of a space between touching the bump stop. This is not a lot. I figure normal driving or going over some road undulations will hit the bump stop.
But I don't think this is an issue, considering Bilstein have designed the shock to be used with lowering springs in mind.
I had a look at the bumstops itself. They are very very soft, almost like a sponge that compresses freely without any major resistance. They do feel a bit different then a normal bump stop I would say. I guess maybe this is how Bilstein wanted them. Im sure they've done more testing then I did.
Regardless of all that, I cannot see the dampers compressing fully or the car bottoming out as the damping forces in the B8's are insane.
Had the car out on a spirited blast and the front is almost stationary, very very little movements, body roll is gone and theres no bouncing at all, and still I find the car extremely comfortable.
I will post some pics later on.
