Has anyone tried something like this?

I’m replacing my rear shocks soon and am thinking about redoing my shock mounts. My car is mostly daily driven and I don’t think monoball units are right for me, but I’m not apposed to something firmer.

I replaced the entire rear mounts with oem units about 5 years ago because I was getting a noise on one side. Want to have something lined up in case the bushings are worn and need to be replaced.

No one has tried these?

I might have to be the guinea pig

I guess not... this is the first I heard of these. I replaced mine about two years ago with the Porsche foam ones... Mine looked fine... I did it because others here said they were a source of noise. I suspect they don't do much heavy duty otherwise they would have disintegrated in very short order... the originals just don't appear very tough. If the price were equivalent, or close to it, I probably would go with these aftermarket things because I keep my cars a long time and this certainly looks more durable. But I am not sure what they would do for performance, because, again, the originals don't look like they would have held if they are really called into duty.

My rear shock mount bushings disintegrated after 11 years... would have tried these if I saw them... but we have to wait again after 10 years

These look like a good compromise between stock and monoballs. I have a set of B16 coilovers in order and might consider these for the rear.

I replaced mine after they disintegrated too. Going in to do struts this time and I think it makes sense to replace them. Porsche only sells the whole unit. I guess I’m going to go ahead and order these.

OP, thanks for taking one for the team... it's your discovery and like I said if I had seen these, would have given it a shot! Let's us know how it feels... I guess it affect noise transmission of bumps from the movement of the shocks...

I just went to buy these and realized that they have a street version and a race version. Great! Now I have to decide which to get. 😂 I’m leaning towards the street version. Anyone following this tread have any thoughts? Want to get them on order since I already have the shock and am thinking of doing the work some time in the next couple of weeks.

I think the street version will be firm enough since the originals are made out of foam. Do you think you need it to have even less flex?

Edcantera

No, not really. The issue I have is that I don’t want to skip replacing them when I do the rear struts and Porsche doesn’t sell the bushing only. You have to buy the whole mount. When the original ones disintegrated I was about to pull the trigger on the mono ball top hats but since I daily the car and don’t have a whole lot of other solid bits in my suspension I figured that it wasn’t worth it. If I were on track more I’d definitely see the benefit in something firmer or solid but for my use the stock, or the powerflex in street version, are just fine.

I am looking into GT3 monoball camber plates for the front but don’t want monoballs for the rears. The street durometer will be good for me as well. I don’t want any clunking going over bumps. I hear that Tarrett and Elephant front plates are good but also hear they could develop noises when they get worn. I hear that the factory GT3 plates last long because of the quality bearings they use.

I just wanted to update the thread to let everyone know that I ordered the street version of the bushings about a week ago but they are out of stock of both versions for 4-5 weeks. I’ll update this post when they come in and when I install them along with a new set of rear struts.

Thanks for posting. About to freshen some suspension parts and these look promising.

I was just looking to order these as well and came across your post. I just called powerflex and they are still waiting on the street version. I might just put the race version in since they should really add any noise. I already have RSS engine mounts so they should be fine.

I finally got the bushings and they look great. Lining up some time in the lift to hopefully get these installed next weekend. I’ll keep the thread updated on how well they work out.
