Polyurethane Subframe/Control Arm Bushings -- Overkill?

[FrustratedMunky]

Hey guys,

I need to replace my subframe bushings and my control arm bushings. I'm thinking about ordering the polyurethane bushings from bmwbushings.com, but since my car is a daily/enjoy-driving-aggressively driver, is polyurethane "overkill" on my car? Can they do more harm than good on my car? I understand that they are more solid, but they may squeak? Is that the only harm? Will my ride feel "stiffer" with them?

Also, apparently when you're replacing the subframe bushings, you may as well replace the trailing arm bushings as well. Is this true? (My mechanic said nothing about them being worn out, so I assume that they're in OK condition).

Thanks in advance, guys.

you should just go stock. It's cheaper, and I think it's just more suited for the street.

I had some aftermarket CABs and they were stiff and quite harsh on street roads. I later gave the CABs to a friend of mine, and popped in the OEM Lemforder M3 offset bushings.

Installing fresh oem bushings will be a night'n'day difference from the worn out bushings that are on our 15 year old bmws.

Heh thanks Hiro. Where did you get the Lemforder M3 offset bushings? I hope I can get OEM subframe bushings from the same place...

I got mine from BMA, though the m3 bushings are about the same price as those urethane bushings from BMWbushings.com.

Ah okay thanks. Yeah, I think I'll just stick to the rubber then. I couldn't find the bushings on BMA online, so I e-mailed Patrick to ask him for prices (he's so helpful, A+ for his customer service)

Yeah I'm with Hiro on this. I installed the urethane ones and for everyday driving they send more shock through the chassis and steering. With no benefit. For track use, they would deflect less and be stronger, but use the ones that work best for the majority of your driving. Also, the offset ones are the way to go.

Thanks for the opinions guys.

How about getting urethane subframe bushings? Apparently, at the subframe bushings, they don't "twist" so there won't be a squeaking noise or anything. Should I go for urethane or rubber?
