Bumpstops

[632 Regal]

what?

I Just went on the first big drive with mine. First bad bump at speed announced the bump stop was 'incorrectly' conceived.

Bilstein need the removed lengths sent back to them- with clear directions on what they need to do with them... one by one using 300lbs of pressure...

interested in checking them stops out, can they be cut down?
I sent you an email...

I have a pair of old M5 stops you can have. Or, I can look at them and tell you if chopping them is a good idea.

Edit: just checked, I tossed the old ones (part of my new regimen - do I really want to keep this shite?). If you wish to trim the stops, trim a bit off the upper end. Leave the bellows section alone.

'tis my office e-mail. PM?

Did you note the edited msg? I've tossed the old BS

However, I think you can cut the OE stops by removing material at the top. Mimic the factory slots et al. The lower end is essentially an air spring when it contacts the top of the gland nut securing the shock insert. The lower end of the BS also holds the dust boot (did you get replacement dust boots? The ones from the Bilsteins won't work).

Anybody have an old stop to do a vertical cross-section and post photo?

I got new dust boots, from when I first did this I remember something about the dust boots falling off cause of the custom trim job I did, Ill order up some stockers and see how well I can whittle.

Thanks Anthony!

Jeff I am remembering your write up about removing the cartridge from the front shock assembly to cut the front bumpstops- mine get the same bang I remember you describing... that's what!

After this weekend's drive in the country I reckon the rear bottoms on the stops also, so I might take an inch from them too...

Am not sure how many 'sections' to take out of the front set: Tiger says 2" or else, but surely Bilstein and Co would know about this before specing the shock: It is a really key spec for every app they work on.

My M-tek springs sit the car higher than yours at the front but the rear of the car is lower- however it is weird though, this should have nothing to do with bump-stop sizes as they should be governed by the fully compressed length of the compete strut and spring assembly ONLY. I even have 9mm lower pads installed.

On a sport spring it is shorter to start with- but fully compressed the strut length should be no difference to the strut using the stock spring.
I keep wondering how it would be if I had the Bilstein shock in there with the standard height spring... My m-tek springs have the same amount of coils, are made from the same diameter material. They are just shorter when uncompressed, and harder to squash of course.

I will put the 3mm pads in the front to help balance things, but I reckon my tow-bar and stereo drops the rear a tad and shoot some pics after that... Nick
