As an inexpensive start... I added Kong yellow adjustable all around and a shock tower brace
Combined with good tires and set on medium... That alone made a huge difference!

I did the ER polybronze bearings. It was a JOB let me tell you. But they work great. I left all the other rubber bushings on the car as I had heard they're a little friendlier on the track. I went for a T-bar delete with 350/550 springs and escort cup shocks. I wanted a DE/streetable car. This thing is very capable on the track.
Currently, I'm in to my elbows replacing the front lower control arms with something that is less likely to fracture at the track now that I'm making 95% use of my car's potential. But I'm giving some spherical bushings a shot up in the front.
I think the rubber bushings on the A-Arm cause a little instability under hard breaking.
I regret not getting firmer springs. I think 350/550 is just a bit soft. But plan out your big suspension upgrade.
Maybe start with some M030 or better sway bars? I imagine roll is your biggest problem and those should help and be an easy upgrade.
If you're going to do polybronze, that's such a bear of a project you probably want to wait until you're sure about what the rear suspension is going to be.

Rear 968 can be had oem new ( I bought mine from porsche dealer two weeks ago. They meet/beat online prices). Paragon website is showing new oem 30mm fronts as being in stock again. Good point above on rear as lindsey had a 5 way adjustable for the rear which gives you more options if desired. They also have some kind of m035 package they put together.
Good luck!

What makes the Polybronze job so much harder? I didn't think it looked too bad from the posts I've seen, but there's probably a lot of little things that are harder than they look...I have a set of spring plates and covers on the way from Lart so I plan to get those cleaned up and the new bushings installed before I tear into the car.

I got my spring plates and covers, but there are some scratches/gouges on the covers - here's the edge where I think the lip of the polybronze bearing would go - it's the slightly out of focus part along the edge nearest the camera (camera wouldn't focus on it):
The actual bore seems ok. Would this be ok to use? Both covers are like this.

When I had trouble getting my delrin bushings to fit, I had some discussions with Carl Potel. He advised me that he had looked at a large number of spring plates and there was a significant variation in the size of the bore, when you get down to a precision measurement level. The rubber bushing really doesn't care so if you are going back with rubber bushings, what I see in the picture looks fine. If you intend to go back with delrin, poly, polybronze, etc. I think it is a crap shoot as to whether your new bushings will fit, without some fettling. As discussed in my article, I had to remove material from my bushings to get them to fit. Even worse, it's a tapered opening. Again, great for the rubber bushings but not something that you could clean up with a simple lathe or circular cutting operation.

That wear on the outside rim looks odd to me. Is there matching wear on the spring plates? It looks like there should be going by that.
There is a lip on the poly bronze bearings that will go there but it doesnt rotate against that part, so I dont think that wear will impact the bearings at all. But something still caused that wear. My 216k mile car did not have that wear.
The Polybronze bearings from Elephant Racing are quite awesome. Outer part is stiff polyurethane to account for the difference in bore sizes and surface quality. Inner race is bronze on stainless with grooves for grease. Very well designed product and a must for any 944 IMHO.

any other bushing you guys recommend ? how about powerflex purple ones for street use ?? any squeaking or stuff like that with those ? ER polybronze does seem to get some good words here but they dont offer full kits as far as im concerned. i own 944 S2. looking to get good handling but also some comfort on street.

We also have both rubber replacement and performance uprated products for every position on the 944 and S2. Is there something you are looking for but not finding on our website?
