I have a 92 900 turbo that I'm rallycrossing (US-style rallycross, it's time trials on cone-outlined courses on non-paved surfacces, not the european wheel to wheel stuff).

I was originally planning on keeping it stock, but I'm running into issues bottoming out frequently. I keep having to fix stuff on the bottom of the car after every event and it's getting irritating.

I'm considering lifting the car an inch or two. I believe my car currently has the stock turbo springs (they have a red stripe on them). I was considering buying a stiffer lowering spring and then spacing it up to ride about 1.5" higher than my current set up. That way I'll have slight more rate (less roll/travel), and obviously be higher up to begin with so I shouldn't bottom out as much. I think with 1.5" damper travel is still okay, and it looks to me like front camber shouldn't be an issue either.

Has anyone tried a lift like this or is it a bad idea for some reason? Or this someone already make a lift kit that I'm unaware of?

Thanks for any thoughts.

Hey, I am currently searching for the same thing for my 900. I ordered a pair of coil spacers from JEGS PN: 555-60833 (New so I cant provide a direct link I guess). My thinking is that the stock rubber spacer is already about 1" thick so these should increase the height another 1.5-2" which is what I am looking for. Otherwise I am just going to modify the spring perches so that I can run circle track springs that can be found in almost any size/ rate you can ask for. They Should be here by the end of next week and I will let you know how they turn out.

I'm interested to hear what develops in this thread. I'm hoping to get my 900 out to a rallyx or two this fall. Mine doesn't seem terribly low, even on the dirt roads I've driven, but I can imagine rallyx is a different story (depending on the course). FWIW, I've got new Moog "cargo control" variable rate rear springs in mine, which definitely gave a little lift over the old stock ones.

EDIT: Here's a photo of the rear ride height on my car with the Moog springs.

Awesome JohnLangv2, looking forward to seeing how the spacers turn out. With a spacer that tall you can stick with the original turbo springs I think, might even have to shorten up a little.

And O2Pilot, those moog springs seem like they just about do the trick for the rear. Seems like the easy button there.

Sorry for the late response, but here is the follow up to what I came up with, I think it might be more than you are looking for but maybe it can be useful to someone else. I tried the spring spacers and I wasn't a fan. They do not work with the front springs and I wouldn't trust them in the rear the amount of flex they had standing still I wasn't comfortable with, so I chucked them. I wound up making my own spacers for the front and kept the stock springs with longer struts. For the rear I used a lift block for the arm and ordered a longer set of springs I also added double adjusters to the linkages and panhard bar to keep everything in the right place. After it was all said and done here is what I wound up with.

To the front wheel arches:
  • Before 26 1/2"
  • After: 28 1/4"
Rear arches:
  • Before: 25"
  • After: 29" with new springs
  • After: 26 3/4" with the rubber spacers (the stock springs had the Saab sag)
Lowest points:
  • Front crossmember
    • Before: 6.5"
    • After: 8"
  • Gas tank:
    • Before: 6.5"
    • After: 11"
    • After: 9" with the rubber spacers
With how I did it this the front and rear arm angles didn't change so it still drives like it did before. I don't think you could go much higher without having to go wild with things. For whatever reason it wont let me add pictures so if anyone wants more details I can do a write up or something.

That's pretty great! For the lift block, am I correct the install point was where the trailing arm meets the body, just in front of the rear wheels?

Correct, and its just a $20 2" leaf spring lift/ lowering block from oreillys with 3/16" steel plates with bolt holes drilled through on top and bottom to keep everything from shifting around

That makes perfect sense! What did you make the front spacers from? Metal, plastic? Seems like something like a Delrin would work reasonably well, but maybe at that point it's just as easy to use aluminum?

Sorry I didn't get a notification that you posted. for the fronts I just made my own spacers out of 3/16" and 1/4" steel for the lower control arms. for the top I made just made a bracket to drop the upper ball joint 1.5" below the upper control arm. I will try and write a short build up of it all this weekend if I can add pictures .

That'd be super... at my pace I'm years away from executing my plan, but it's always nice to have things to think about. ;)
