Today we’re going to talk about e30 front-control arm bushings, specifically the ones that are on e30s, e30 m3s, e36s, and e36 m3s. Just like all of our other poly Bushings we make in the United States. They come in three different flavors. They come in 80 poly, which is a soft poly, you’ve got your 95 poly, which is a hard poly, then you’ve got delrin, which is incredibly hard.
E30s and E36s both came with options. They either had offset front control arm bushings, or center control arm bushings. That really depends on your goals or what your car had originally. E30 m3s all had offset front control arm bushings. Early e36 m3s also had offset control arm bushings. Standard e30s had center control arm bushings and late model e36 m3s also had center control arm bushings. Could you upgrade from a center to an offset? Yes, you could and you would basically gaining about 10mm of track, because you’ll basically move out your wheels.
That’s one of the main things why you would switch to a offset front control arm bushing. The 80s by far are most street friendly. It’s going to absorb a little bit more noise. It’ll still transmit a little bit more noise over factory, just because of the solid fact that the bushing is actually solid in geometry, where you would find the stock bushing would have holes. It was made for comfort. It is made to give a little bit. That way the noise was kept a little bit lower. 80 is your street-friendly one. It’s good for autocross, it’s good for occasional track days. Overall it’s a good bushing.
Your 95 is your step up from that. A car that’s a little bit more dedicated to tracking. A little bit more noise is okay to make sure that the control arms in the front don’t move. Delrin is your full, all out race, drift application where noise is not a concern. You don’t want the control arm to move at all. It will transmit a little bit more noise, but it will get the control arm to basically not move at all in unwanted directions. That would be the main purpose of having that.
The symptom of a bad control arm is basically, it’s that symptom when you first get your e30, basically you go over a bump and that steering wheel shimmies and wobbles and you don’t know what’s going on. That’s usually the control arm bushing. You go over a bump and the wheel does whatever it wants. The whole control arm moves as a unit, when there’s nothing to attach to. Cheap upgrade at the age that these e30s and e36s are nowadays, this is probably neglected part on the car. It’s something worth looking in to even as a factory upgrade for your e30 or e36.
