Recently done a complete suspension overhaul on my car, including this setup. My question is, did you re-fit the standard bump stops back?

It's just when we were fitting them we were unsure, but read the shocks had them in built, so didnt bother. This then led to a big knocking over bigger bumps, which turned out to be the top of the shock travelling up and hitting the underside of the top mount.

As a result I have now fitted a new pair of oem bump stops and this has now stopped, but there is no suspension travel before it goes into the bump stop, so I'm just not sure if this is normal or what really? Don't think it's affected the way it rides but I may be wrong, really didnt push the car before as I was too scared of damaging something when it knocked!

Any thoughts appreciated.

It's only the inverted Bilsteins which have the internal bumpstops - the ones with the really big 'shafts' - although I think the B8's are, aren't they?

I get a banging over big sharp bumps which I've always assumed is the damper rod reaching maximum extension under rebound, but no knocking.

(The rebound damping on the B6 / B8 is a bit on the soft side...)

I run the standard bump stops at around 1/3 their normal size just to hold the damper rod boot really. My quick beer mat calculations said that the spring will reach maximum compression before the damper bottoms out anyway so bump stops are not strictly speaking required.

(I'd check that yourself though as my calculations were more of a good estimate really...)

Yer, I guess it is more of a bang, rather than a knock Rich. In between having none fitted, and fitting the full length ones, I had ones fitted which had one ring less, and although it did help, I still got the bang on not really that big bumps, so decided on the full length.

It's fine, just don't know if the ride is being conprimised by being straight into the bump stop.

I've got this setup to fit later in the week.

So is it ok to fit without bump stop's or do I need to get some?

If I do need to get some, would standard size ones be ok?

This thread has got me thinking now. I just used the standard bumpstops on my 6 when I fitted the same setup.

I do notice that the top mounts flex (move up and down) a lot when i compress and uncompress the front suspension. I wonder if it is because the shock hits the standard bumpstop and presses into the top mount?

Am I right in thinking that as my 6 is lowered est 30-35mm at the front I should have trimmed off 25-30mm from the front bumpstops?

Do you need to re-use the original top spring pan? As the Bilstein B8's which I've received don't have one.

Weirdly, the instructions also state that the dampers have built in bump stops, and that you shouldn't use the original ones.

Are these just general instructions and not specific to the B8 dampers?

They're built in the lower casing - the 'shaft' you can see is actually the body of the damper, so the bumpstops are around the true damper rod which is in the casing.
If you're using the stock tops mounts then you use the original top spring pans Yes

So, I don't need to use the original bump stops?

Does anyone know if you can buy new top spring pans from Pug?

Sorry for all the questions, just want to make sure I do it right.

Cheers for all the help so far. Thumbs up

I'm not sure how you tell, so here's some pictures of mine -

I'm guessing I need to re-use the original dust boots?

They do indeed fit over, just use a little fairy liquid or whatever as they're quite a tight fit. I think you would need to fit them as the built in ones don't seem to come into play soon enough, so the shock body hits the bottom of the top mount, or at least it was for me.

And even with the standard length ones fitted, I can still get a clonk of I hit a large bump at speed and certain angles of attack so I dunno, didn't there would be anything like this as it's such a popular conbination but there we go.

Ah, they're not inverted, just me getting mixed up then - in that case, use bumpstops.

This setup transformed the feel of my car, though I fitted 21mm rear torsion bars at the same time and my old rear shocks were practically seized and front ones shot LOL

So did I need to cut off 20-30mm of the original bumpstop when i fitted these shocks? Currently I'd think I'm hitting the bumpstops sooner than I should be?

Whoever asked yes I used the standard boot covers for these shocks.
