I have done some "HERO" rallies with my car and am planning more, however I feel the need to stiffen up the suspension as it is a bit too roly poly!
I have Bilsteins all round but standard springs: what are the recommendations for uprated springs (and ideas as to where to get them would be handy)?
Thanks

How old are your springs? New ones will be stiffer.
Later front springs are stiffer -'75 on I think - someone will correct me. I have these on my red car with 1 coil removed and anti-roll bar as it is a '71 model.
On my blue car I have rally springs all round and anti-roll bar on the back (non-std). Also has roll cage so it feels very stiff and turns-in very nicely - better than the red car. Not sure the front ARB is much benefit with the stiffer springs.
I think Malbrad can fix you up with new springs and advice or I have a spare set of used rally springs. PM me if interested.

It isn't a blue one is it? Thought I caught a glimpse of one on The Rally of the Tests when it was on Motors TV last week? Anyway regarding springs the old works springs with Bilstein shockers and no anti-roll bar was the best set up so I'm sure Malbrads will be able to supply you.

Please put some pics up in the rally section - it's compulsory!!

Which is the most? (All three!)
Most gravel -> soft car
More tarmac -> stiffer car
Track, autocross more stiffer springs

My car little street.
Aotocross and trackdays
Front springs 130N mm and rear 50N/mm
Anti rollbar front std, no back.
Now with coilovers 140/60 and anti rollbars front and rear.

(130N/mm) Front Springs are saab 900 (1979-1093) rear Combi cupe for caravan.
Std 900 CC also goes
std 900 sedan more like rally 4V springs, a little stiffer

Saab rally spring front 50-60N/mm.
I do not know rear, but they were progresive.
I guess around 20-30N/mm

Hi Fuling,
Sounds interesting, do you have pictures of the coilover and rear anti roll bar set up?
Not something I plan to do ever but interesting to see!
Cheers
Gareth

I have a set of standard (green markings) C900 CC springs to go on the front of my 96, but I don't dare fitting them with my standard spring compressors and I'm not sure whether they're too firm for standard road use. Hope to buy or borrow the original Saab tool one day to get the job done and see what they're like.

My C900 is currently fitted with Kilen springs, which suck. I may try fitting the rears to the front of the 96, they're a bit shorter than standard springs. Good excuse to buy a set of heavy duty rear springs for the 900!

Curious to see some pics of your coilover conversion fuling.

Now that looks very good fuling! I've been thinking about coilover conversions myself, but never got any further than some basic measurements. I like your front and rear swaybar set-up as well. Did you build your own coilovers or did you borrow them from another car?

I have Leda coilovers.
But they are out of business what I know.
Standard lengths with special damping curves.
I have 100mm strokes
(front and rear)

Great info, thanks. I'm quite happy with springs and shocks at the front because nose weight is normally constant, but it would be great to have some sort of level adjustment system for the rear of my 95 van. I don't drive my cars in anger, just want to be able to carry some weight or pull a trailer from time to time. If at all possible, I prefer to use parts from a standard road car; it keeps the cost down and I like a good old root at the scrappies with a tape measure.
