Non-adustable. You can get them custom-valved for your particular configuration though. They also work across a wider range if bumps than Konis, so adjustability isn't that big a deal.

I think some of the Koni or Penske triple-adjustable racing shocks (rebound, low/high-velocity compression) are pretty cool... You'd have to do a double-wishbone conversion in front to use them though...

Hey Danno-

*****some of the Koni or Penske triple-adjustable racing shocks are pretty cool... You'd have to do a double-wishbone conversion in front to use them though*****

Would changing a 951 to double wishbone be in ANY WAY cost effective? What about doing it to the rear too? I assume a double wishbone is similar to a multi-link? You know what I'm getting at already I'm sure- E36M3- you had said they had a multi-link (5-point?) rear. Do they also have a multi-link FRONT too? Would converting a 951 to something like that be possible and/or have you ever even seen or heard of anyone actually trying it? I'm talking about doing it for a relatively reasonable amount- that's a relative call too I guess

Danno

Well, the double-wishbone idea was to fight the detrimental camber-change as the car leans. This is most prevalent in the front. That will allow me to run reasonable springs & damper settings for a decent ride. Yet as the body leans, it doesn't tip tie tire over onto its side. In fact, you can even design the geometry such that as the car leans, it dials in MORE negative camber (relative to ground, sum of camber change in suspension - body-roll angle).

In the rear, I'm not sure you'll get more grip by going to a double-wishbone design. But it will tame the semi-trailing arm's built-in trait of lift-throttle oversteer.

We'll see what happens. I'm thinking of grafting the upper A-arms from a 928 onto my car. I'll need to cut/weld/fab up a custom spindle to attach to the 951 bottom arm and the 928 upper arm...

Koni does indeed offer a bolt on double adjustable race shock application for the 944. The 2812 series shock is Koni's top of the line racing shock which is used in F1, CART, IRL and professional sports car racing. Our 89 Turbo was the first 944 fitted with these units . The strut version of the 2812 is the 2817 which is also a double adjustable, high pressure gas monotube application.

So Jason what does a set go for? The website has nothing for the fronts.

I'm not sure if this is what Jason was talking about or not, but....when I asked for a price on the fronts of a turbo S/89 turbo...I was quoted somehwere's around $400 a piece. The end result was externally double adjustable.

What they do is take yours as a core...and give you someone else's who have already been rebuilt by Koni. Koni takes a while to rebuild them, so paragon basically makes the process go MUCH faster.

Not in this case.

The 2812/2817 are a complete unit. No cores necessary. I don't know what Jason gets for them, but Truechoice wants $1,500 per corner for struts and I think something like $1,000 for the shocks.

Yes, you read that right.

SERIOUS race dampers. And unfortunately out of my price range.

I will likely be building my own struts utilizing the Koni 8611 double adjustable race insert (unless I can find a strut for the early 944 with a 50mm tube - then I won't have to build the strut). Now what I need to find is the appropriate double adjustable rear damper to go with it. I don't need, or really want, a threaded body because I cannot use rear coilovers in ITS.

You can install either an 8610 or an 8611 unit, though the 8611 unit takes a little modification to the sturt bearing.

Check out the September eddition on Excellence, Page 147.

Edit- whoops, I think this will only work for "late" car suspension (1987- NA, 1986- turbo).

I'll check them out. Thanks. I don't have the Sept issue, but I'll see if it's still at the newstand.

$3950 - complete kit including mounting hardware and springs. Built to order. Currently for 87-91 944/S/S2, 86-91 951, and 92-95 968 (all originally sealed strut applications).

These are the converted M030 height adjustable units - (8742-1007S) increased valving, and made double adjustable (add bump/compression, retain rebound) - that price represents useable cores for turn-in.

Anybody want to buy a slightly used kidney?

I wish I had the budget for a set of these. I'll have to make do with a set of 8611 inserts up front and God only knows in the rear.

Thanks. Got the magazine yesterday. That's basically what I will end up having to build. Those appear to the the Advance Design System (Ground Control) set-up they show on their web site.

One thing, the article has the 8611 and the 8610 backwards. The 8611 is the double adjustable and the 8610 is the single. The article also says the double adjustable isn't very suitable for street use, but I disagree. I have a few friends running them on their road cars and even helped a friend install a set on his Sentra SE-R a few weeks ago. They are sweet and while the ride is is a bit firm due to the higher rate springs, it is anything but harsh. Very sweet. Also, I don't have my Koni catalog with me, but I would bet the 8610 jounce rate falls somewhere within the adjustable range of the 8611.
