Does anyone know of any less expensive alternatives to the $80 bushings available from Paragon?

I haven't found anyone else that carries SR bushings in delrin.

You can get the stock ones. new stock rubber will make a big difference.

Just get delrin. You only need the drivers side anyway.

ideola

Not sure I understand why only the driver side...?

If you get Delrin, make sure they fit right and there's zero gap. Here's what happens when another 944 racer installed Delrin steering rack bushings that didn't fit right...



The #66 car went around a 70-mph immediately in front of a pack of traffic, lost steering control, and spun out big time right in the middle of the turn. I'm the red #22 car, and I came within inches of wrecking into him hard, and I wasn't the only one.

Combine that with the various problems we've seen with Delrin torsion bar bushings and I have no desire to ever use them... poly bushings, or even fresh rubber, work pretty well, cost a lot less, and haven't caused any major problems.

If you look at the design, the drivers side bushing takes almost all of the torsional stress. At least that's what I think.

The part available from paragon can be a real pain to get in. Its a tight fit though which is a good thing i guess.

I'm no fan of Delrin myself (or polyurethane either), but how is that even possible with a failed rack bushing? IIRC, the bushing lip on the rack would be captured in the mount even if the bushing isn't there. If it wasn't, I'd think the stock rubber bushing would shear out of the mount - especially as the rubber deteriorated. There had to be a bigger issue with #66. There's only about 1/2" play in the rack without the bushing that should have allowed him to maintain control.

I was thinking it might be related to the big orange "R's" on the car

CurtP

I didn't even notice until you pointed it out.

Can you elaborate? I've heard nothing but positive things about Delrin.

To the OP......I've seen a PU bushing. Dont' know where it came from, but I have seen one.

I knew they were out there somewhere:

And a very interesting related thread on 951forums.com:

I think maybe I'll just replace with new OEM rubber.

Does anybody sell polyeurethane bushings for these cars? It seems like there is nothing between the stock rubber stuff and then delrin/ball bearing bushings.

That's about as affordable as you are going to get.

Problem with these cars is that the the control arms don't rotate in a perfectly linear path, because of the way alignment is done on them - caster in the front, toe on the rear. As there is misalignment, control arm bushings are hard to do with anything but rubber or spherical bearings.

Umm, we ain't talkin' about control arm bushings...
