Besides all the things that Jim ( Oddjob ) mentioned I think after you sort out possible issues, the biggest bang for the buck, IMHO are the M030 sway bars ....
There was a pair selling here a month or so ago ..Josh is believe was selling them

Thats not to say the M030 suspension is not too soft for aggressive track use - it is. But its an ok starting point for a beginner.

Youre right - I disagree. Having driven various 944s with all sorts of suspension setups on the track over the years, there is a relatively dramatic difference between a stock 944T boge suspension and a Turbo S M030 Koni suspension. Stock rate is 125 lb/in, Turbo S is 160 lb/in which is nearly 30% increase in rate. And the big difference is the damping rates of the single adjustable konis. Combine that with the larger swaybars and harder durometer rubber bushings, and the cars have a much better feel when cornering and at high speed.

Looks to me that the tyre pressures could have led to a squirmy sensation that could feel 'wobbly' on top of other issues?

I feel like my 300/28mm/Koni setup is pretty much how the car should have left the factory. It's much more in line with the damping of a modern sports car.

I haven't actually driven a 951 with Boge suspension, mine came with Konis installed by the PO. As a completely stock 951 with Koni yellows on full stiff, i thought it handled like crap for a car that had such a highly reputed suspension in its day.

Is it possible that your PO had trashed the shocks, springs, tires ? ?
I must admit the stock tries that came with the car sucked !! Goodyear's
When I changed over to the Yoks, it made a world of difference.
My car was so stiff my CD player kept skipping ... and I never felt the car handled poorly .... It was like it was on rails ....

Well, i guess i can safely say:
People have different preferences on stuff like this. Some people buy a Porsche and expect it to handle like an F1 car and ride like a Cadillac (not gonna happen!), others (like me) will probably never be happy with the way the car handles.
I do think that damping technology has gotten pretty amazing in the last few years. I'm not unhappy with my Koni's (i transferred them from my old car to my current car, they're still in awesome shape!). I do think that there are better out there. I have no doubt the Turbo S does well for what it is today, and what it was 20 years ago. I also think that with modern dampers, you can get much more out of the car without giving up much.
Besides, if you're going to go through the whole car and replace stuff, you might as well replace it with better stuff, right?

But I was just referring to the orig. set up, as being very competitive then.. I can't really comment on today's susp mods, because I haven't used them or driven on them
Best regards

Was it made clear if the rear shocks are in fact the koni yellows? If not, get some to match the front koni yellows. These are cheap (in terms of shocks) and a good bang for the buck.

Has anyone mentioned the torsen tube mounts? The whole rear suspension is mounted to that tube, and the carrier blocks are a pretty big chunk of rubber. After 20+ years, that stuff is probably worn slap out. I know my father-in-law had this issue when he was starting to DE his car, he had replaced almost everythign else, and the rear end was still wobbly.
Oddjob, thanks for the correction on the sways. My 89 is apparently one of the later ones, as it came with a 16mm. I just assumed all of them did.
