The World's Best Selling and Best Performing Rear Shock Mount for z3/4/E36/46 Models !

The BMW factory rear shock top mounts are well documented as a very poor design, even when brand new they perform VERY poorly, far too much movement in them, and they are essentially worn out every 20- 30 k miles.

Say goodbye to vague real chessis feel rear end clunks! With the introduction of the Rogue Engineering Rear Shock Mounts, you have a high quality, rebuildable, easily serviceable rear shock mount.

Fits the following vehicles...
All E30, including M3
All E36, including M3, Z3 and 318ti
All E46, including M3
All Z4, including MZ4

Rogue Engineering Rear Shock Mount Set includes:

Two (2) Rogue Engineering 6061-T6 CNC, Anodized Rear Shock Mounts.
Four (4) Shore A 65 Bushings (2 required per mount).
Two (2) 303 Stainless Steel Bushing Spacers (to be used with standard 10mm rear shocks).
Four (4) 303 Stainless Steel Washers (2 required per mount).
Four (4) Yellow Zinc plated serrated lock nuts.
Two (2) Shock Tower Reinforcement Assemblies (with 10.9 hardware welded).
Two (2) factory gaskets (#3352 1128 734).

Problems with Factory Mounts
The factory BMW rear shock mounts are generally a little soft, to provide the most possible acoustically dampening in the vehicle. However, design precludes them from being stout enough to withstand the rigours of aftermarket suspension, or even badly damaged roads. A decent sized pothole can send a perfectly good factory rear shock mount to pop out, making it entirely useless necessitating replacement. Upgrading to E46 M3 rear mounts (a popular alternative) is not a guarantee that it doesn't happen again and again.

Rogue Engineering Rear Shock Mount Features
By producing a rear shock machined from 6061-T6 aluminum, we are able to attain a more stable and stiffer platform which to mount the top of the rear shock. However, rather than use race-only spherical bearings or even overly stiff urethane bushings, we specify Shore A 60 hardness rubber bushings (approximately 30% stiffer than the factory bushings) to allow for street comfort and compliance. Our findings show that overly stiff urethane bushings do not allow the rear shock to move, making the attachment of the lower part of the shock under strain.

The construction of the aluminum shock mount plate and orientation of the bushings makes it impossible for the bushings to "pop out" in the manner which the factory style mounts fail. Since the bushings are rubber, when they require replacement, rebuilding them takes only a matter of minutes. Only 4 bushings require replacement (for a pair of RSMs) and are available at extra cost.

Other important details include the use of 303 stainless steel components (compression washers and spacers) for long-lasting corrosion resistance. All other hardware is metric, and either Grade 8 or better, treated with a yellow zinc plating, again for corrosion resistance.

Another feature is the reinforcement assembly which secures the rear shock mount to the vehicle. By reinforcing the top of the shock tower in the vehicle, it protect against the rear shock from ripping out the sheet metal. The reinforcement has its hardware welded to it, allowing for the rear shock mount to become a bottom-mount design. This means that if the rear shocks need to be removed, it only requires removing the two nuts and the single bolt at the bottom of the shock. No need to completely disassemble the trunk area to gain access. If being used with a rear strut tower brace, the reinforcement assembly may be mounted from the bottom, so that the rear shock mount can be secured in the traditional manner.

The Rogue Engineering Rear Shock Mounts are designed to be used with standard 10mm rear shocks, but can also be used with 12mm adjustable race shocks with the use of optional washers.
