common problem with the factory design is the shock does not take
only a vertical load - the trailing arm has an arced range of
motion. This forces the shock to pivot around the upper shock
mount, which eventually causes the adhesive bond in the stock
rubber mount to fail - a process expedited when combined with
new design allows this pivoting motion and dramatically extends the
life of the mount. We are so confident in these mounts that if they
ever fail, you can trade them in for a new set at no charge! Made
with high quality Buna rubber to eliminate squeaks and a high
production stamped steel plate, costs for this extraordinary mount
are close to the BMW factory price. Fits all 1984-present 3 Series
cars (including convertible).

Great Shock Mount
From Norman Howard of Mililani, Hawaii on 3/25/2015.
Highly recommend this item - similar to the cost of the OEM mount but with the lifetime guarantee. Well constructed and the OEM rubber cover will fit - just not as tightly as with the OEM mount.

Great product fast shipping
Time Will Tell
From John Bennetch of Grottoes, Virginia on 12/8/2014.
E 46 Cars are notoriously hard on rear shock mounts when stock shocks are replaced with stiffer units. My 330i driven fairly conservatively absolutely trashed some new "HD" mounts in 10K miles when I installed Bilstein HD shocks. These look much stronger. Time will tell. Bimmerworld stands behind their products so at least if they don't I'll get a free replacement!

nice heavy duty stuff.

Do yourself a favour and use some anti-seize on the shaft of the shock before slipping it into the metal sleeve of these RSMs. I went to remove these RSMs and found the metal sleeve seized to my shock. Unfortunately I'm going to have to cut the metal sleeve off if penetrating oil doesn't help. If this was mentioned in the installation instructions it is my bad.
