Hi,

I have a 944 and have been looking for replacement Spring Plate bushings other than OEM, Delrin and Polybronze.

For auto-x use for example, I want to firm/fix up the deteriorating bushings I have to something that will not break the bank or be too flimsy. I have yet to find an affordable performance option.

If I was to cast a mould and create very stiff polyurethane 75D or maybe even 95A durometer...would anyone be interested in buying for a price higher than oem rubber yet 50% less than Delrin?

Don't know if you've seen these...but they are excellent quality, reasonably priced and easy enough to install. I have been using them for 2.5 years now...they might make them in their "sport hardness" if you ask.

I did, but did not see any mention of a stiffer option. You emailed them to request those, was it additional cost?

No I just got the regular ones, but I know they have a sport-hardness option for some of the other bushings they make, so maybe if you requested it they could accomodate.

OEM rubber or polybronze are the only good options. Rubber works via elastic deformation so there is no friction (and thus squeaking) during range of motion. Polybronze is a bearing and hence is low friction with minimal noise. Polyurethane and delrin require movement between the bushing and the spring plate or torque tube surface. Although initially greased at installation and relatively quiet, after a few rounds in the rain both will eventually drive you crazy with squeaks.

that sucks....well this is primarily an auto-x car and glad I only spent $50.

I will take moulds anyway and try a moderate focused durometer stiffness poly to use with lithium grease. Very curious to if they will hold up with slight deforming.

Used to be the case but these days the "quality" made Poly bushes like the Powerflex are designed with grooves to keep the grease in and lips to keep the rain out. Once fitted it is difficult to get any water between the bush and the metal even if you direct a high-presure hose at it.
