Rear Subframe Bushing Insert

[Kujiwara]

As title states, has anyone used these subframe bushing inserts from Hardrace? Anyone found polyurethane bushings?
Seeking feedback on how they work on the street/fast road. Solid aluminum bushings are too hardcore for my use

I had these inserts installed on my B8.5 S4 before and made a pleasant improvement to the tightness of the rear end without introducing noise and only a bit more vibrations/feel from small bumps. But they actually fits snugly into the void of the bushing. The Hardrace ones appear to only restrict one end of the bushing and doesn't go in very deep and only appears to support the outer bits of the rubber on the bottom side of the bushing, there's more void between the rubber on the top of the bushing. If anyone has other insert suggestions that is welcomed too.

Did you get them installed in the end?

Just watched a Kern417 YouTube video and was thinking the same thing.

Definitely interested in following especially if/when Powerflex releases their solution. Solid mounts are a PIA.

I think if there is no good poly options by the time the rubber subframe mounts wear out I'd be willing to try aluminium, the Final Edition Supra does have that and it's still a street car so it makes me feel a little better.

Just wanted to add that the title of this thread sounds like automotive dirty talk lol.

That's a good point. Having the Toyota (BMW) certified part will be nice for reference and comparison. Found this for the GT4: https://store.51gt3.com/products/su...eawZzWhMXwd7xvIOufKRKkKyDyP09aWoanIgU7WnK95NS

Anyone can verify if that website is legit?

Number 2 and 3 are the solid bush for the Supra's rear subframe and according to the press material for the Supra Final Edition, it states that it runs the same solid mount like the GT4 race car, so I'm wondering if it's the same exact part.

Any updates on this? Did anyone find better inserts for the supra?
Thanks

Can anyone confirm that these will fit the supra

The subframe bushing inserts will fit except for the smaller rear one (circled). I have the powerflex black installed in my car for a bit now.
