Buying an S2 Coupe - Am I walking into a world of pain.

Yes, you need Billy's 34-030868 for the front. They will come with the tool to do up the top nut with the seal in it but not the rubber gaiter iirc. Don't forget to do the "Billy mod" and drill a small breather hole at the bottom of any strut you fit Billy monotubes to (there's a sticky on here about it, https://www.s2forum.com/forum/techni...ll#post2105783).

You can fit KYB 366008 to the rear if you want to save £200+ on using Billys on the rear. (They are narrower than the inside of the rear 55mm strut but come with a spacer to fit them)

The supplied cap from Bilstein does not fit my strut.

Or am I missing something here.

S2 struts are unique to S2's as far as I remember awkward as always

Remember having a nightmare when I bought mine years ago sent 2 sets back got the right ones on the 3rd attempt

If I can find the shocks... may end up going koni

Don't forget to order the strut cap tool also.

I'm not sure if you can just use different caps. But it looks like you need Bilstein 34-030868. These are the ones I have fitted to my coupe and I have a spare here to go on. It has a thread cap diameter of 55mm and a tube diameter of 45mm.

Yes they could the the shocks I need, on the phone now to order them.

The shocks for my coupe had the same diameter tube front and back, just different caps.

Now that is a problem, everything else is as should be, but that is not.... quick call to Bilstein should get you the right cap.

Yep, the included instructions should tell you all about it.

[B5NUT]

It also looks like this cap has the seal for the shock body.

[Bowie69]

That is as designed, the shock is a monotube design.

You should have got new boots with them as well? These clip into the groove just under the shoulder, under the thread.

All as it should be

[B5NUT]

But even the shock shaft is a different diameter OEM is 25mm V Bilstein 33.5mm that is a fair amount of difference will all the upper sections just bolt on as they are a completely different shape (but same size thread)?

Yes, the body of the shock with Bilsteins are narrower, they just adjust the size of the cap. I fitted some B6s earlier this year, so direct recent experience.

Properly torqued down (I made a tool.... but you can buy them) they won't budge.
