E30, E36 and Z3 Delrin offset front control arm bushings
BMW E30, E36, Z3,SOLID DELRIN OFFSET FRONT CONTROL ARM BUSHINGS (75D)
WHAT ARE SOLID DELRIN OFFSET FRONT CONTROL ARM BUSHINGS AND WHY DOES MY E30, E36, Z3 NEED THEM?
WHAT IS THE DIFFERENCE BETWEEN "OFFSET" & "CENTERED" BUSHINGS?
- Wider track
- More caster
- More camber
These will make a massive difference in front end grip and steering response. The factory rubber bushing was designed for comfort, not performance. They allow the control arm bushing to "float" in the center. Thats great to keep the noise down, but allows for TONS of play in the steering. When your bushings are old and busted the problem is even worse and dangerous. Using our delrin bushings improves performance by reducing deflection. Delrin also has a much greater longevity than rubber and poly bushings. Considerable improvements in steering and braking will be noticed as delrin shines in track use. It has reduced pivot friction as well as virtually no deflection. Keep in mind though that delrin will add noise and ride harshness into the cabin.
For that reason these offset solid derlin front control arm bushing are meant to be used in race vehicles only. The delrin will not deflect like the OEM bushing. Includes everything needed for installation. You will get two front control arm bushings.
These are the solid delrin "offset" bushings. If you would like the centered front control arm bushings (like standard e30 was from the factory) then click here. We highly recommend professional installation as these will require a press to install as well as remove your old bushings. Let us know if you would like these pressed in ask about our exchange program.

WHY SHOULD I REPLACE THE FRONT CONTROL ARM BUSHINGS ON MY E30, E36, OR Z3?
At the age of these e30s, the front control arm bushings are often very worn and beat up. When you go over a bump the front wheel will shimmy and hop and do all kinds of weird business. Most people do not realize that these are a maintenance item and should really be done before lowering the vehicle. These delrin options are the ultimate in performance. But for that reason, they WILL increase road-noise if used on a street car. Price for 1 pair of mounts. The logic of going with delrin really depends on what the primary purpose of the car is and how much noise you're willing to tolerate.
WHY USE SOLID DELRIN BUSHINGS OVER POLY BUSHINGS IN MY E30 ,E36,OR Z3?
Well, we will start by mentioning that the factory bushings we made of plain old rubber. What that means is that BMW put them there because they are designed to flex and absorb energy making it a little comfy on the street and not allowing a sh** ton of noise to get in. That's wonderful if your car is a street car, but on an all out track rat, drift car, or full out race car build you want your alignment to stay constant. Get it? Flex = the enemy. That makes Delrin the ultimate bushing for all out race vehicles. It is incredibly strong, has no flex, and low coefficient of frictiom. That means no suspension bushing deflection ( which means no geometry change). We don't recommend delrin in most street-use cars because of the amount of NVH but HIGHLY-recommended for track cars. If you are looking for a compromise between delrin and rubber, then check out our poly line. We offer them in a few flavors to suit your needs from OEM+, to dual purpose street/autox/track cars. Keep in mind that solid Delrin will outlast your OEM rubber bushings.
