The rear shock mounts on all 1984-2007 3-series/M3/Z3 are known for premature failure, particularly when used with an aftermarket suspension.
Initial indicators of failure is a clunking sound which will eventually lead to complete mount failure... and even damage to the sheetmetal of the shock mount tower, requiring expensive bodywork repair.
While various bearing and urethane alternatives have been devised, many of these are only sufficient for racecar use due to increased noise, vibration, ride harshness, and short service life.
The "ultimate" solution comes directly from Meyle, the manufacturer of many of BMW's original components. Their "HD" (Heavy Duty) version features a revised conical center section that makes it virtually impossible to push through (see cutaway picture above). The result is a durable, quiet, and trouble-free mount at a reasonable cost.
Included in our kit are the Meyle HD mounts, the required BMW gasket and hardware, and stainless steel reinforcement plates for the shock tower mounting hole which strengthens the sheetmetal as a precaution against expensive sheetmetal fatigue-related failure.
