New bushings certainly make a difference on e30's that are driven hard. On the idea of eurethane bushings, I am sure they make for a stiffer ride, but at the expence of ride quality. If you daily drive your car, the stiffness to harshness ratio may not be worth it for you. The bushings that seem to make the most difference are the front cabs. When replacing these you can upgrade to m3 spec offset bushings, or solid mount aftermarket bushings. Since stock and m3 bushings are one time use only, its not a bad idea to go ahead and replace your control arms at the same time. In the rear, the subframe bushings are often shot causing a loadshift under hard turns and hard shifts, replacement deffinetley yields benifit.

The Powerflex bushes really tighten the car up considerably.

The only one that affects ride quailty is the rear subframe bush simply because of its size.

All of the others make no difference.

The control arm eccentric bushes are a must have, the steering changes so much. Its more positive, its much more stable at high speeds and the braking is transformed.

For the money its one of the best upgrades out there.

The best thing about them is that if your control arms ever need changing the bushes are not wasted, simply pull them off and whack them on the new control arm, no need for a press.

On my previous car I fitted new std rubber twice and Powerflex once in the middle. New rubber is as stiff as Powerflex bushes. But it softens over time. Powerflex gave me a lot of trouble with sticking bushes, and no amount of Copper slip ever sorted it out. I fit new rubber on my car.

I would deffinetley go with the m3 offset bushings. They do not effect ride quality at all while providing sharper responce by way of increased caster. The rear subframe bushings are deffinetly a pain, but not out of reach for an ameteur. It is possible to drop the rear subframe with the trailing arms attached, but I would suggest dissasembling the entire rearend and replace the trailng arm bushings at the same time. Replacing the subframe bushings is really just a lot of labor, it is very straightforward when you are under the car.

I have the front camber and castor plates and rear camber and toe trailing arm bushes and I think they reduced the understeer a little. It wasn't a big difference but I think when I accelerate full throttle out of a corner it doesn't push the front quite as much, it never understeered much in the first place but I think now it is a fraction better.

I also have front M3 offset polyurethane bushes but that was a while ago so I can't say what difference they made. Rear subframe bushes are probably next, and then the ARB bushes and upgraded ARBs at the same time.

My car is all over the road at speed, I was going to change the whole bottom arms and track rod ends etc. Should I just get new bushes instead?

sounds like an ideal time to do both bushes and the arms etc.

I think powerflex kits are about Ԛ£65
