Long story short - I'm collecting the 944 rally car from my mechanic tomorrow to take on a rally.

The car is currently on koni yellow dampers but the fronts have a tiny bit of play in them so we have bought a pair of Bilstein B6 inserts to go on.

However...

Just heard that the Billies won't go into either the koni housings or the stock (new) Sachs dampers that we have to hand.

We have zero time on this now - is there any magic fix to get the Billies on usin either the koni or Sachs stock housings?

Thanks,

Ben

Id have liked to have offered you some, but Ive no experience in this are on these cars.

All I know is the one collapsed damper on mine wasn't helping!

I'd like to know more about the B6 installation myself - do Bilstein offer any advice?

From what I gather, they fit straight into the older threaded top strut bodies, but if you have a later sealed strut body, you need to cut this as close to the top as possible, then cut the top from a threaded strut body just above the spring seat and insert that into the sealed strut casing and weld to one another. Then the B6 insert fits tightly into the early strut sleeve, and the Bilstein clamping nut screws up to the thread of the early strut.

It basically says to me that they were designed to be used with the threaded strut bodies, but they are sold as suitable for the later sealed one as well. Realistically from Bilstein, all it needs is a similar upper bush & foot nut setup to that of the Koni conversion, but I'd like to hear how they suggest they were designed to fit with a sealed strut body.
