rear subframe bushings?

[Roadcone]

What's the best route for replacing bushings back there? i've noticed the rear seems to bind up on tight turns since i've put the supersports on the car. on my last car this was supposedly due to subframe bushings binding and releasing.

is it better to replace the bushing or to install the "stops"

For reference here is what i'm talking about.

I'm not sure if these are solid or pliable.

The Beatrush stops look like they are metal.

I have the Whitelines and they make a big improvement. You will get extra NVH with any of the pliable solutions, but it's not really that bad. I'd be a little worried about the solid Beatrush ones though.

Get the Whiteline stops. I don't think your bushings are binding at all but they definitely help. A lot of the JDM brands make solid ones, I probably wouldn't go that route.

Just be careful whichever ones you use to get all four bolts started straight cleanly before tightening anything down, those bolts LOVE to crossthread.

I made a similar thread a while back, but has someone actually used the soild ones and can say with confidence that the NVH is worse? I mean, technically your rear subframe should not move and it should be the suspension doing the work correct? Yes Japanland ha s better quality roads but there must be a reason why most of the JDM vendors prefer to go with a solid one...

I get a feeling it`ll be an improvement in comfort to go with the soild bushings if the car is equipped with good quality dampers such as Ohlins, etc...

Think about where the dampers connect, and where the subframe bushings are. Even with really high end dampers, the LCA's and UCA's are still attached to the subframe, so any bumps or vibrations on either arm will be transfered to the subframe, and the more solidly it is mounted to the chassis, the more of that will be transfered.

The reason some people like solid bushings is "because racecar". The reason the rest like them is because the more solidly everything is connected, the less any geometry can change and the more you can feel what the tires are doing.
