Rear shocks for S/944 NLA. Options?

mike.gamble · **Posted:** Mon Oct 22, 2018 7:54 am

I'm trying to come up with a suitable option for a replacement for the rear shocks after it seems they appear to be no longer available anywhere?

https://porsche924.co.uk/forum/viewtopi ... 46&t=32048

I've tried all the obvious options but with no joy.

The KYB ones suggested have different lower mounts (possibly shim?)

The N/A ones have a 12mm lower mount not a 14mm required for the S (Could this have a new lower bush fitted and if so, how easy is this to get done?)

I know the sports versions Koni's - Bilstens etc are still available but, I wanted to keep my ride standard as it's my intention to use the S as a daily driver and don't want a harsh ride.

I've contacted ZF Sachs to ask of the possibility of a run of them being manufactured but, I'm not sure what sort of response I'll get.

At the moment, the S is jacked up with the rear shocks off. I know I could pop the old ones back on and keep using the car but, it seems a silly situation to be in!

Any other suggestions?

Bilsteins are NOT harsh. The stiffness of the ride is determined by the stiffness of the springs NOT the shock. That said, the shock should be valved accordingly to manage a stiff or soft spring. Bilsteins are set up for stock springs/torsion bars as far as I am aware.

Or go for a set of GAZ. They will valve and spring them in whatever flavour you want them.

When I swapped my old dampers for Bilstein B6 all round it didn't noticeably make the ride any harsher than before

Anyway, to the issue of standard spec. I have read that it's possible to have the 12mm sleeve reamed out to 14mm on the steel arm versions - but I haven't tried it myself or even looked at one

Must be something here to suit as an adaptor n/a to S? Use a taper if nothing else works.

I’m really just after something I could take out of a box and fit on to a car, not faff around with setting it up.

It would (possibly) be an easier solution if the correct size bush with 14mm sleeve could be found? The powerflex solution mentioned by Stan could be the way forward? I may give them a call and see what they recommend.

Here is a sleeve, but taking it out to 14mm might leave it a bit thin?

You don’t set anything up. GAZ do road spec shocks as well as race. Phone them and tell them what you want. They send a box. You fit them.

£68ea for rear adj dampening shock built to order. Which means you can have whatever ride or fitment you want in a box AND soften or harden the dampening once on the car ........... https://www.spring-loaded.co.uk/product ... rsche&pg=2. Front inserts are also available for a matched front and rear set up.

I have the GAZ std dampers in my car (they didnt have the other kits back then when i built the car), i think its a great solution for a std car, I had them on my std n/a first, they can bet set so soft that the car feels like a boat. or much much firmer if you want. Put the adjustable knob in the middle of the range and then go, it makes the car so much more fun to drive with some decent dampers.

Of course its strange that there arent an OEM replacement, but i feel this is a fairly nice and reasonably prices alternative.
