BMW e30 solid delrin rear subframe bushing (75D)

Meant for your all out track, autocross or drift E30  monster, these solid Delrin E30 rear subframe bushings are the ultimate upgrade. These solid derlin standard rear subframe bushings are for high performance race vehicles only. They solid mount the rear subframe to the chassis removing all flex from the suspension. This will make the subframe not able to deflect and move in all kinds of unwanted directions. Pair these up with our solid rear trailing arm bushings for a no compromise track setup.  These are much stiffer then the OEM units (75D) which will cause some added NVH. Includes everything needed for installation. Includes both bushings as well as  aluminum sleeves. These will reduce play in the suspension substantially compared to old and mushy bushings. Please note: If you use these with adjustable rear subframe conversions you will need to cut down bushing. If you would like us to do so for you, let us know (see pictures). These are the "standard height" bushings. If you would like the subframe raised 12mm to compensate for unwanted rear camber, then we have our "raised versions" of these as well. 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 into your subframe!

The 12mm raised subframe bushings reduces camber by 4.0 - 4.5 degrees (better for a street application). Average change is from -5 degrees to -1.5 degrees (depends on suspension setup). The standard subframe bushing kit  does not change camber (better for a track application). 

Comes with a lifetime warantee.

Fits BMW 3 Series E30 (318, 323, 325 & M3) DOES NOT FIT  iX model). 

These replace OEM part number 33311129144 (33-31-1-129-144)


Price is for a pair (2 units). Enough to do 1 car.


Why should I replace the rear subframe bushings in my e30?

The rear subframe in the E30 is often the most neglected on project cars. Not only are they notorious for going bad, but when  they do, the subframe will move around causing the rear end of the car to become unstable and at times unpredictable.  This is oftern paired with annoying clunking sounds and creaks. From a performance aspect having a loose subframe messes with your suspension's alignment and settings. The solid rear bushings make for better suspension alignment and tighter feel. WILL increase roadnoise if used on a street car. Price for 1 pair of mounts (includes races). 

Why use delrin bushings in my e30?

Well we will start by mentioning that the factory bushings we made of rubber (duh!).  That means the 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). Thats 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 dont recomend delrin in 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 Delrin will outlast your OEM rubber bushings.
