What are you using? What have you tried? And at what tracks?
79 928.Car should be around 2800lbs with Devek adj. front bar, modified rear. Shocks, still undecided. Thanks for the advice D.K.

Ive had luck with the devek stage II koni /hypercoil 750 front and 475 rear. however, id wish i was 50lbs heavier front and rear.

Mark, what does your car weigh and what do you think of Leda shocks?

shaaark89

previous car 2900 lbs, 1000lb front, 600 lb rear hypercoils over koni single adjustable. present car 2800 lbs, 1000 lb front, 750 lb rear over custom valved bilsteins. rear shock mount points are custom though, so spring rate does not necessarily compare to stock mount points well.

cars about 2750# with a couple of gals of gas.

Tom, why did you go with the Bilstiens over the koni's The reason i ask is i'm not convinced with the koni's being adjustable enough off the shelf. If i'm going to the expense of custom then that opens up a whole new bunch of options hence the questions regarding Ledas
I don't mind a bit of fabricating to make somthing work but i don't want to be saying man i wish i had bought the --- , same goes for the spring rates... just want to get into the ball park.
Thanks for the feedback guys .

750 /475 is proven to work on cars in the 2700-3000lb range . once you chance pick up points, like Anderson and Tom, all bets are off and you have to recalculate or mirror they attachment points. I can tell you this, i would have no problem being 800 and 500 lbs on my set up. then, i would be able to adjust down with shock valving and rear swaybar settings.

right now, im full max on everything. and its the perfect set up for my hp and the tracks i see, but no adjustment capability

Check out the Ledas at Racers Edge, Knoxville TN . My shocks are mounted, but I am about 6 weeks away from finishing the car. The spring rates quoted by racers edge were much higher than you would think. Since I am not a suspension expert, and this car has not been to the track, I really don't want to talk about spring rates to confuse the issue.. Call Racers Edge. I was very happy with the 24 click adjustable shocks and the price was fair considering the scarcity of options for the 928. The machine work on the upper and lower spherical mounts is first class and a very nice setup. All the parts just clicked right in place. As far as the spring rate???... I will know more in May.

Leda sales guy in UK gave really high rates for race setup when I ordered 600/400 street setup for local S4. Can't remember exact number but they were much higher than what's been mentioned here if I remember right.

i went with the bilsteins because that's what was on the car when i bought it. seriously though, when i had the koni's i just kept them set at full hard. of course they were only the singley adjustable ones. i've been pretty happy with the bilsteins though i'm far from a suspension expert. all i can say is that the setup i have allows me to put the 500+ rwhp to the ground pretty effectively.

Many of you have far more track experience with your 928 than I do. Actual seat of the pants experience goes a long way. I run my street 1989 944 turbo on the track with 400lb front springs and many of the 944 race guys are running 1000/600 front- rear combinations on a strut type suspension. The 928 A-arm suspension is a different animal with different geometry. The Racers Edge people emphasised the important factor is the "wheel rate" which is calculated from the geometry of the suspension movement, shock mounting, shock travel ect. You cannot compare "spring rates" from a 944 to a 928. Due to the ratio of the 928 suspension movement ,the Racers Edge is recommending a much heavier spring. Taking into consideration the additional weight and size of a 928 versus a 944, it makes sense that the 928 should handle a heavier spring.

My street/track car has 800f/550r springs @ stock mounting points and Bilsteins. (3250 lb curb weight) The previous owner chose this combo. Only downside is a lack of damping adjustability. If I had the budget, I'd love to try a set of 4-way adjustable racing Motons.

spode134

No kidding! The Leda's are half way there with the single adj. It's hard to justfy the double adj with resvoirs for triple the money! my racing budget is going fast as it is.

Along these lines, does anyone know where to get stock-fitting 4.5" (ID) springs? I've looked but it seems the hypercoils and such don't go that wide.

Springs are cheap. It's the mounting bits that costs the $$.

Currently have an "entry-level" track setup with single, internal adjustment Konis and (old) Eibachs in front (450#) and the former fronts in the rear (400#).

Does anyone know what the stock spring rates were?

My '82 came with the Comp. package which was supposed to be firmer than standard, but I've never seen any specs on actual rates.
