I am having a hub refurbishment undertaken, so thought that with everything off the car, it made sense to undertake a full suspension overhaul as the parts are off anyway, and the replacement parts are cheap.

The car is fitted with poly bushes at present, and rides well (in my opinion, I am yet to drive another Pantera!), but I am recommended to go back to OEM. What would anyone recommend?

If I go Poly Bush, any particular brands/model that anyone recommends?

Would you recommend that I replace all the bolts/washers involved?

Springs, shocks and suspension arms look okay, and may survive the cull!

Current cars stance is like so, is this about right? I like the ride height as I can drive it hard on rough roads, and am yet to ground it out, or catch the front splitter.Side Profile

Why do you want going back OEM when you are happy with the drive? Honestly I equipped all my rides with polybushes and I am happy with it. Longer life than OEM and you can play a bit with the stiffness (not necessary using the strongest one) when you make the choice. Have 1500 mls on my Pantera speedo with the bushings and no complaints. 

I guess the question isn't around being happy and going back, per se.

I should explained. I didn't fit the polybush, so I wouldn't know what make/model they were, but I am undertaking a total suspension, brakes, wheel and tyre refresh, so would replace the bushes anyway.

The team undertaking the work recommend I switch them out for  Metalastik bushes.

If I can keep sharp handling, and get less noise, more comfort, that has to be a good thing, no? I am afraid I am not super technical when it comes to suspension, so someone might have some interesting insights.

Thanks, Tom

The oem style rubber bushings have bonded center and outer so the rubber is stretched/springy in operation, whereas most of the poly bushes on offer don't have such as they are not fixed and rotate around the center tube which leads to the squeak.

Dennis Quella has a style that has a hex steel core so the bushes do not rotate on the center but are forced to act more like the oem rubber ones and as there is no poly on center rotation they don't squeak either!

If it ain't broke don't fix it! Poly bushings are easy as they don't require a press, personally I'd stick with oem rubber, there's nothing wrong with them other than they are 35 years old and need replacing.

Beautiful car Tom.  I love the color.  Do you know what the color and paint code are?

Hi JimmyM,

Thank you, I absolutely adore the colour, real depth, and a nice tonal variance in different lights. Lots more photos and video on my Instagram (same hook as here).

I don't know the code, but it is Porsche Iris Blue Metallic.

It was on the 993 range of Porsche 911.

My suspension squeaks a bit also and I figure now is a good time to overhaul it while waiting for the gearbox. Everything I have appears to be stock OEM with Koni 82-1702 and rubber A-arm bushings. My plan is to send the shocks to Koni for a rebuild, powder coat the A-arms, springs, sway bar etc gloss black. My goal is to retain the OEM look and ride, I plan on installing new rubber bushings rather than Poly. Should be complete in a couple of months (hopefully) as I already miss driving the car....

Thanks for the advice Joules. Haven’t measured caster yet, will probably verify settings in the next couple of days prior to tear down. Tire size is 345/35/15 in the rear and visually the caster setting looks like about a 3. I know when upgrading to larger diameter wheels, most people increase caster, but with my 15’s, the tires wear fairly even and handling is good. 


Stay with Poly. They are more predictable load wise and a snap to change out if necessary.

I see no advantage to the original rubber units at all. Plus, you need to press them in and out.

It is the poly that has the reputation of squeaking but in my case I think the rubber is worse and absolutely deforms.

The graphite impregnated are the quietest and Joules recommendation of the offset bushings is a very trick and good solution to front end caster.
