Powerflex Urethane Rear Subframe Inserts - BMW E36 (Track-Series Set)
A complete 8 piece Aggressive Street/Track Kit to stiffen your rear subframe mounts without doing a full E36 bushing replacement.
Reinforce your E36 3 series' failure prone rear subframe bushing/mounts WITHOUT having to remove or do a full bushing replacement! These subframe bushing inserts install into the rear subframe of any E36 318i, 318is, 318ic, 325i, 325is, 328i, 328is, 328ic, 323i, 323is, 323ic and E36 M3 (3.0 and 3.2 liter.)
These amazing and clever polyurethane inserts install on both sides of your stock BMW rear subframe bushings, filling the empty voids in the bushing to reduce bushing deflection, increase bushing rigidity and longevity, improve cornering and improve rear end stability. And with Powerflex's Black Series urethane compound, which has a stiffer 95A durometer polyurethane, you'll firm up the stock bushings as much as possible for aggressive street and track driving. Perhaps best of all, they install far easier and in MUCH less time than a full subframe bushing overhaul.
These inserts are specifically designed to work with BMW factory rear subframe bushings:
Rear Subframe FRONT bushing part numbers:
33319059300 (33 31 9 059 300) as used on all E36 non-M and non-ti models
33319066671 (33 31 9 066 671) as used on all E36 M3
Rear subframe REAR bushing part number:
33319059301 (33 31 9 059 301) as used on ALL E36 (non-ti model)
These are guaranteed to fit the above original BMW subframe bushings. If your car has aftermarket subframe bushings, these inserts will most likely not work, as the inserts are molded to match the factory voids perfectly.
If your stock E36 rear subframe bushings are still in good (or new) shape, these Powerflex Bushing Inserts are an ingenious way to protect and improve them! You don't need to remove the bushings from the subframe to install these inserts, making install a breeze.
This is our Aggressive Street/Track Subframe Bushing Insert Kit which uses Powerflex's 95A durometer "Black Series" urethane, which is firmer than the yellow 70A durometer standard "street" compound, making them ideal for aggressive street driving, HPDE, driving schools, or other track driving. These are also available in the softer Yellow compound, which is appropriate for standard street driving.
