Powerflex Urethane Track-Series Rear Subframe Inserts - E90 335d, E91 all

Reinforce your E91 3 series wagon or E90 335d (diesel powered) BMW's failure prone rear subframe bushing/mounts WITHOUT having to remove or do a full bushing replacement! This complete set of Subframe Bushing Inserts is for all aggressively driven street or track driven E91 chassis 3 Series Touring Wagons OR E90 335d (diesel) including:

2006-2006 E91 325i / 325xi Wagon / Touring
2007-2012 E91 328i/328xi Wagon / Touring
2009-2011 E90 335d (diesel models)
** ONLY FOR USE ON DIESEL OR TOURING WAGON MODELS (See Part # PF-RSUBFRAME-INSERTS-E9X-E8X for sedan, coupe, convertible or diesel models.)

These amazingly simple 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, reduce unwanted subframe movement, increase bushing longevity, as well as improve cornering and rear end stability. The Powerflex Black Series compound delivers increased stiffness for the best handling and reinforcement. 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 the original BMW factory subframe bushing and are guaranteed to fit these 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 E91 wagon or E9X diesel rear subframe bushings are still in good (or new) shape, these Powerflex Bushing Inserts are an ingenious way to protect and improve them! The best time to add these inserts is when your bushings are still like new! Keep them failure-free and improve handling BEFORE age and wear kick in! 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.
