Rebuilding Bilsteins
I have Bilstein shocks on the 79. They have a 928 part number, and look stock? Are these worth having rebuilt, or are the aftermarket Bilsteins sold by places like 928 motorsports much higher performance?

From what little I know about having Koni's rebuilt for a 944, they are only a little less than buying new ones ( like $20). YMMV with Bilsteins and the 928, but I would say not worth it when you factor in sending them in and waiting.

Oh, I live about 20 minutes away from the place that rebuilds them. I was curious about how well the stock biltseins performed against the ones sold as a coilover kit from some of the 928 performance places.

The rebuild costs $65 each IIRC and you have new(ish) Bilstein's valved to whatever you would like.
If you can deal with the used appearance, it's the most cost effective way to go.
I have been running a set of rebuilds revalved for tighter springs for a couple of years now and they are just like new but better.

Thanks Dave, that's the answer I was looking to hear. Does anyone one know what valve setup works best on a stock bilstein on a 928? I might be taking these up monday to have done, just want to make sure I do it right the first time...
Thanks!
Thanks!

What works best for most is stock valving with stock springs, but what works best for you will depend on what you plan to do. There was a thread recently on someone having his shocks revalved for track use with stronger springs.
Which shocks do you have, early green or adjustable spring height?
I've been thinking about having some of my shocks redone, and have a few notes;
Shocks purchased new other than factory equipped have a lifetime warranty to the original purchasers with proof of purchase. Typically Bilstein ships a new shock instead of rebuilding for warranty items.
No proof of purschase, or not original owner, rebuild is $65 each, dyno testing and report is IIRC $24. Rebuilding has no warranty.

with stock springs, just opt for a rebuild. With some of the much stiffer springs some of us are running we need a lot more dampening.
You should be fine with the originals rebuilt.
