These are the best rear shock mounts that we have found for the E30, E36, E46, Z3 & E85 Z4! Featuring CNC-machined billet aluminum mounting base with a replaceable urethane bushing (replacement bushings are just $15 and are changed in minutes!). These mounts are excellent for either street or track because of their low NVH (noise, vibration, and harshness). Plus, the superior design will far outlast the life of stock mounts - maybe even the car itself. You'll never think twice about your shock mounts again! These shock mounts are a direct replacement of the stock mounts so they fit all shocks with the BMW-standard 10mm shock shaft, including all factory and OEM shocks (Boge, Sachs, etc), H&R coil overs, Bilstein shocks and PSS, PSS9, PSS10 coil overs (except the B16 Ride Control Kit). This is sold as a package with new shock mount gaskets, washers, and Nyloc nuts.

The main mounting bolt for the differential in the E36 is susceptible to shearing off during extreme driving conditions. This can cause internal damage to your diff, leaving you stranded at the track or on the side of the road. Active Autowerke's differential support bracket eliminates this issue forever in under an hour installation.

The rear springs on the 1999-2005 E46 323i 325i 328i and 330i models have a chronic broken spring problem. If it hasn't happened to you yet it will. Springs are nothing more than exposed steel and they rust easily. After a while a section of the spring actually breaks off.
A broken spring is very dangerous - the spring is no longer mounted correctly in the suspension and it cannot support the weight of the car, especially when cornering. The ride also suffers as the suspension is no longer able to absorb the bumps and impacts from the road. Aside from a visual inspection of the spring itself you might notice a clunking sound or banging noise coming from the front or rear. An inspection of the noise should also include other related items in the suspension: bushings, ball joints, links, mounts, etc. We also recommend replacing the rubber spring pads on the top and bottom of the spring because they lose their shape over time. Check if your car has 5mm or 15mm thick pads.
The factory BMW springs sell for $140+ each. We sold and replaced enough while working in New England that we were able to get a strong grasp of the issue and come up with our own springs that are an improvement over the factory springs in every way. These springs are made in Germany using high grade spring steel that is then shot-peened for longer life and powder-coated for protection. These are the same height as the stock replacement BMW springs which makes them a direct replacement.
Sold only as a pair.
