Bill, if you want Öhlins PM me and I'll get you in touch with a friend working there (at the HQ in Stockholm).

Bill,

if your car had a sport suspension, then it had the Boge red shocks and like att the S4-on 928s, the Marked Brown springs. Trust me and change your springs as they are the most overlooked item on a 20 year old car. The shocks of choice for me are the Boge Red. If you want a further sporty ride, you can go from brown springs to orange - something that went on the SE, CS and factory toy racing 928s around Weissach.

Sincerely,

Bill Ball

I called Koni. The tech guy was very familiar with the 928 and said they had worked on valving with DEVEK and had not had any complaints about valving. He was puzzled too by my observations, thought somehow I just got some bad shocks, offered advance replacements. He said they used to do that for free but got burned and now charge your credit card and refund on receipt of the old shocks. That's very fair and common practice.

Kaled: I will look the springs over more carefully when I get them off. I did see a 928 part number on one rear spring but it doesn't match anything I could find - the number is 928 313 ? (looks like an up arrow) 1822. So, I will consider other springs after I get these off and figure out what they are.

Anders: I don't think I need Ohlins. If my new shocks will do what they do on George's car, I should be happy. BTW, George hit 185 MPH yesterday.

Bill the Koni guys must have a shock dyno and can easily TEST your old shocks and tell you what it is and what it should be. I would think you might like some stiffer springs like Eibach. Less suspension change under loads makes the car feel much more stable and reduces camber change from body roll.

I seem to rememeber someone here in the uk had a problem with new shocks and it turned out to be the way they had been stored...?

Wish I could remember, I think the cure was to remove from car and invert for some time ......anyone else heard this one ?

I could try and find out from the person who reported this...

Actually Jim, I think the Eibach's are too soft for what Bill is doing. I will be using 700# fronts and 450# rears for my 86.5' when it comes back out and it's lighter than his. Those bumpy high speed sweepers are not easy on soft springs. Most people on a track never get to corner at 130mph and up...who cares about ride, it's all about control!

Dave, Bill spends 99.9 % or more of his driving NOT in an open road event and when you mention " bumpy " that may well be an argument , one good reason NOT to run very heavy springs. And as far as the .."Most people on a track never get to corner at 130mph and up" You need to come play at Willow Springs where a good car averages over 100 mph and turn eight is FAST...

Ketchmi

Jim, you need to bring the old brown bomber out to Miller Motor Park and have some fun. We hosted the ALMS this weekend and it was one helluva show. The 3600' straight followed by a switchback is pretty interesting...

But back to the topic at hand...I'd much rather be safe for the limited time I was travelling at extreme speeds than be cushy for the rest of the time. I'd guess that stock springs are pretty much bottomed out on some of the corners during ORR and that doesn't allow much road holding ability when the roads are not very smooth. These are Nevada highways that lead nowhere, they are not in the best condition.

Jim bailey - 928 International

I have heard that it is a very nice track ! You know if "I'd guess that stock springs are pretty much bottomed out " then perhaps the Koni shocks were damaged by bottoming out especially possible if the rubber "additional spring" 928 343 527 01/02 was left off the shocks....

Bill Ball

I will most likely put it back together with the stock springs, if only to see how much the shocks have been contributing to my problems. I can do a very decent test locally on my twisty test circuit. It has some high speed bumps that instantly told me my current Koni shocks were bad compared to the original Boge. So, if the new ones are good or not, I will know. George is running his original stock springs and his car is stable. Dave, I know you like it hard!

BTW, Dave, I can't thank you enough for trying to get me fixed up this weekend despite the fact that you were away on a break. You, Garrity, Stan and another guy I talked to on the phone were all so "git 'er done" I felt guilty saying no, but I think it was the right choice. I could have other issues. In fact, I'm going to look over all the bushings real carefully and replace any that are accessible without a lot of fuss and any that are dodgey.

Oh, and I will be studying the coilover assembly parts as I take them apart.

Bill..." Dave, I know you like it hard!" .....Ah too much information

Ketchmi

He's ridden in my "street car" with cut down Weltmiester's on front and stock front springs on the rear...it's a little firm.

Jim, you have one of the most warped minds I know...In time you may catch up to me! I cringed when I read that, knowing it wouldn't pass without comment.

Bill Ball

Heh. Sorry about that, Dave.

pmotts

I imagine not many people realize what a great group of guys are at Motorsport in SLC. I can't thank them and there "git 'er done" attitude enough for their help on my trip to the OCIC.
If they ever get there website done people will be shocked at how many parts they have in stock

Bill, I'm suprised you even need front shocks. With that supercharger of yours I'm ceritan your front wheels are barely touching the ground!
