joey ,
it took weeks for them to arrive because customs got them when they arrived in uk
then i had to pay the import duty , then i had to pay extra to get them to deliver on a saturday morning , then i waited in and they delivered to the wrong address ................... NIGHTMARE !!!!!!!!!!!

and now they're wrong !!!

but ,
the actual bodyshell didn't change over in 91 , nor did the trailing arms etc.
the only thing that did , as far as i know , is the struts and topmounts .

so .........
i should be able to change my top mounts and fir these rear shox ??

anybody know whay they changed them ??

if i have to send them back i will have all the hassle of getting a refund on the duty i paid , shipping costs , then the chance of the new ones getting impounded again !!!

I recently fitted Bilsteins to the rear of my car, and was concerned that there were different part numbers but was advised that it wouldnt matter as it was only the mountings that were different and these would change over ok onto the new shock absorber shaft, and they did. Re the shockie length, it is probable that the springs are shorter anyway so this will counter the difference in the shock absorber length. It is a reasonably easy job to remove the rear springs to check, as long as you have a spring compressor to change them over. Try them first before returning them. From what you went through to get them I think that would be less hassle.

so you put the earlier shox on a later car ??

ian c - u.k

springs are the same

I was advised that there was no difference by Performance Products. I surmised that they only supplied the one part. If it were me in your situation I would remove one of the rear spring assemblies and compare. It would involve approximately 2 hours work, ie remove rear blower pipe work, rear blower, undo three nuts on the top mounting, jack rear of car up, support wheel assembly on a box or something similar, remove bottom bolt, remove shockie assembly, loosen top nut, fit spring clamps, remove top mounting, spring etc and refit to new unit.

can do it easy enough
as everything on rear is hand-tight with copper-slip , as i'm half way through fitting the eibach springs !!!

but i dont want to make the new bilsteins look "fitted" , in case of arguments with the tuner in la i bought them off !!

I checked the original shocks at lunchtime. The length from the centre of the lower bolt hole to the very top of the shaft is approx 640 mm and the diameter of the threaded to section is 12 mm.

anyone know why porsche changed ??

is it in adrian's book ??

fore!

I'm just purchasing H&R and Bilstien setup too (there's been a lot of people on this subject lately - everyone getting close to 60k miles?).

I searched the board to make sure I got the right part numbers - here's the latest from Ryan at Bilstien in California (800-537-1085). For our cars 91 thro 9/93 left front is VE3-5277-HO, right front VE3-5278-HO and rears B46-1547. They don't differentiate between the turbo/RSA and the regular 964 - one fitment is for all cars.

You'll find part no's V36-0384 and V36-0385 listed for the fronts too. These are no longer produced and have been superceded by the 527#'s.

Anyway that's what they told me. Hope that helps someone.

fore!

and another thing....

The best price I could find on the Bilstiens was at www.Shox.com. As a rennlister you get an additoinal $30 off. I paid $639.

hey M
thanks
any chance you can ask the bilstein guy why they have 2 part numbers for the rear shox , one for 89-90 , the other for 91-on

Ian, my car is a MY92 C2 Tiptronic.

fore!

Ian,

I have it from the horses mouth. Lou at Bilstein in California.

The earlier shocks have a longer thread at the top. All valving is the same on the earlier and later shocks. I asked if the early ones would fit the later car. He wouldn't recommend it and mentioned that a 993 that they worked on the other week had a very small gap between the top of the shock and a wiring harness that the longer stem might interfere with. Check it out on your car.

FYI - I asked about the difference in "Sport" and HD shocks. Both have identical valving the difference is in the length of the stroke with race springs having a shorter spring length.

Let me know how it shakes out.

BTW - my shocks from shox.com are sched for delivery first week in April.

Cheers,

M

mine are the ones with little thread showing .

but what i dont get is ......................
if the body is the same , and the trailing arms ,
and the only difference is the top-mounts , and shocks .

can i change my top mounts and be done ??

the tuner in la says its no problem to change them , i just dont want the hassssle of approaching customs for a refund , only for there being a chance i get hit again when the new ones come in .

plus the cost of shipping them is nearly 200 pound
