BMW E30, Z3, E21 & 2002 80A POLY REAR TRAILING ARM BUSHINGS


WHAT ARE 80A POLY REAR TRAILING ARM BUSHINGS? 

These 80a E30 rear trailing arm bushings are meant for Auto-x and track application without the associated "harshness" of solid Delrin rear trailing arm bushings. These bushings can be used in street performance cars, but some NVH will be added. The stock rubber trailing arm bushings deflect and allow the rear semi-trailing arms to move in all kinds of unwanted directions.  These 80a rear trailing arm bushings maintain stock suspension geometry while keeping noise to a minimum and will outlive OEM rubber bushings. These RTABS are much stiffer than the OEM rubber but great for street application. The kit includes everything needed for installation; bushings for all 4 connecting points on the trailing arms as well as steel sleeves. When you're upgrading your bimmer, the type of bushing you choose comes down to the purpose of the BMW, and sometimes your beast can also be your daily. Take a turn like a champ, but also get to work. Comes with a lifetime warranty. Replaces OEM #33329061945  




WHAT ARE THE BENEFITS OF E30, Z3, AND 2002 POLY REAR TRAILING ARMS? 

These poly rear trailing arm bushings maintain stock suspension geometry; keep in mind that these poly bushings are much stiffer than the units (75D) which will cause some NVH. The Garagistic kit includes everything needed for installation.  That kit will of course include RTAB bushings for all four connecting points on the trailing arms and the accompanying steel sleeves needed for the install.  We touched on the benefits of BMW poly rear trailing arm bushings a little above.  When looking for a nice compromise between street and track, go poly. Now, what exactly is Polyurethane? They are a group of organic polymers that are normally grouped with rubber. The variation of polymers can be manipulated to various durometers and physical properties to work with most any application. Poly bushings have an amazing ability to absorb a lot of strain and a substantial amount of trauma without permanently deforming; UHMW and Delrin bushings tend to be not as forgiving.  Moreover, poly bushings are resistant to water, oil, gasoline, salt, antifreeze, and most solvents. Why would you pick poly bushings over rubber ones?  Rubber is subject to degrade with the introduction of any solvent; that means your little oil leak on your E30 will degrade your bushings over time. Our Poly RTABS are  also ~20% lighter than rubber bushings.




QUICK NOTE ABOUT USING OLD TRAILING ARM BOLTS OR ALUMINUM RACES:

Please keep in mind when shopping around for trailing arm bushings that a lot of competitors use aluminum for the race instead of steel. This is not a good idea. It's not a good idea because nothing that rotates should be aluminum as it will wear due to the soft and malleable nature of aluminum compared to steel. Your BMW OEM race was steel and so is ours.  


Another note-worthy concern when purchasing bushings is in regards to hardware and tolerances; we make our products compatible with our parts as well as our competitors. We designed our parts for cross-compatibility to make things a bit easier for you when shopping for you E30. Our BMW poly trailing arm bushings are a prime example of this, they are not only be compatible with our camber and toe kit but others as well. The bolt diameter on the eccentric hardware (OEM BMW) for those who make their rear subframe adjustable using our camber and toe kit (while they have the subframe out) is bigger then the old oem e30 hardware (which could possibly be worn as well). So for this reason, we recommend that you replace your old, worn, tired and small stock hardware for bigger (and tighter fitting) hardware which you can find in the options list above. This is optional. However it's a great way to get an even more precise feel in the trailing arms you cant get from other kits out there.  Do it once, do it right. Kit includes 10.9 grade bolts, washers and even nylon locking nuts. Everything for the install.




WILL THESE POLY 80A TRAILING ARM BUSHINGS FIT ON MY BMW?
These bushings will fit the following BMW's:
  • 1602
  • 2002
  • E12
  • E28
  • E24
  • E30 (318 320 323 325 M3)
  • E36 (318ti only)
  • Z3/M
  • E21


WHY WOULD I REPLACE MY REAR TRAILING ARMS? 

The stock rubber trailing arm bushings deflect and allow the rear semi-trailing arms to move in all kinds of unwanted directions causing an overall instability. As we mentioned above, this energy displacement slows your cornering and reduces confidence.  Replacing your trailing arm bushings on your e12, 2002, e30, z3, or e21 makes for much more fun putting your power where it needs to be. After all, what good is power if you cannot put it down? Stay the course with these bushings and learn the true difference they offer. As we mentioned above, the difference between poly bushings and rubber ones are pretty apparent. With heat, age, and oil leaks and other solvents leaking on your rubber bushings, they inevitably decay/erode resulting in decreased performance and ride quality in your bemmer; your cornering will suffer because of it along with many other things.
