I installed the FF black inserts first (and I didn't pay full price for them - I think I paid around $100). I decided to use them because my mount at the time was in bad shape, and I didn't have the tool to change it. I figured the hardest ones would be best due to the nature of the existing mount. I've since bought a new mount/bushing and I figured I'd change to the yellow (PowerFlex) inserts both because the bushing will be new and hopefully the yellow inserts will reduce the NVH a little bit while still stiffening the stock mount.

Thanks everyone, the powerflex look much the same as the FF so I think ill just go with those in the yellow spec. Like the idea of black but I know it wont be a good move haha

Here you go, the roll bar bushings are solid polyurethane, the tranny mount insert is not. You can see how I designed it to have an initial easy flex to stop vibration during idle and cruise but when you put your foot down and a lot of torque is delivered they compress up to a point then get more solid.

I never actually got around to fitting a set on my car and I wasn't sure anyone would want to buy them as a kit.

^^ Those ^^ look pretty cool Chris... Maybe best of both worlds. Maybe price them between the PF and FF points if it covers your cost with a reasonable profit...

Very interesting. I wonder how long that material (foam?) will hold up?

The material (the white parts) is thermoplastic polyurethane, so essentially the same material as the cast (orange) parts. Its very strong, even trying to trim any stringy bits of leftover plastic with a razor is hard with it.

I've had my 3D printed poly roll bar bushings on the car for around 5k miles now and no problems. For the tranny insert the material is under a compression load so the best case for longevity.

Yeah I might look at this again soon, I need to give my printer a service etc and replace some worn parts and then run the numbers on the cost of raw materials Vs what I can sell them for plus labor time and figure out if its worth it.

The last couple of months I spent some time on another project which is a bit off topic here (although I do carry one in my car for protection). I designed the worlds first 3D printed taser and sell all the files to make them at my website for $16, pics and movies on this page on my website:

I thought about listing this in the for sale section on rennlist; but I'm unsure if it violates the rules here as its not porsche?

I was trying to figure out what your "roll" bar bushing was. It looks to be a "sway" bar bushing. If so there r several different diameters depending on the application. If u do sell them u will want to include that info.

Let me know if you move forward on the trans insert.

If you are getting one, get the powerflex. No reason to overpay for a piece of plastic.

Seems pretty oversimplified, but maybe it is that simple?

Functionally speaking, are the two products the same durometer/shore hardness? Are you comparing apples to apples?
