Polyurethane Control arm bushings

[Alpinerob]

I am very interested in these bushings..My entire front end is stock which is fine with me but im looking to get more life out of the control arm bushings and maybe just a little more rigidity without making it feel like the springs are cut...

Do polyurethane control arm bushings make the ride rough?

Does anyone sell them already installed in new lollipops?

Poly bushings probably won't last enough longer than rubber bushings to matter, and they will increase NVH. If this is a pure track or race car, the increased stiffness of high durometer poly bushings is worthwhile. But if a street car, that isn't necessary or particularly desireable. I prefer M3 solid offset bushings on a street or mostly street car. Those bushings will typically last as long as the control arms. Handling will be improved with little increase in NVH.

Poly bushings are not difficult to install, the larger challenge is getting the oE bushings out.

I am a fan of OEM E30 M3 control arm bushings. They're only about $45 a pair and they're factory, no added noises!
