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.

M7 Strut Reinforcement Plates 53-510101 are the ultimate solution for MINI owners facing the common issue of strut tower mushrooming caused by heavy impacts from shocks and low aspect ratio tires. Over time, MINI's shock towers can develop a convex shape, disrupting suspension alignment and leading to a noticeable pull to one side. The M7 Strut Reinforcement Plates (SRPs) address this problem by reinforcing the sheet metal and shock top plate, creating a durable surface that resists bending, even during hard impacts.
Designed specifically for the R50 Base Model Cooper, the R52 Convertible, and the R53 Cooper S, these SRPs are an essential upgrade for any MINI enthusiast. Constructed from CNC machined billet aluminum and black anodized for durability, the 1/2" (13mm) thick plates cover the entire surface of the strut tower, distributing loads evenly and providing peace of mind.
Whether you drive your MINI daily or push it to the limits on the track, M7 Strut Reinforcement Plates offer a cost-effective preventative measure against expensive suspension repairs. Easy to install in less than 20 minutes, the SRPs use the stock nuts for mounting and come with instructions that also guide you through fixing existing mushrooming.
If you are concerned about strut tower mushrooming and looking for improved handling, the M7 Strut Tower Brace (STB) is the solution. This is the ONLY strut tower brace on the market that features anti-mushrooming technology.
Repeatedly, we've heard the same complaint: strut towers mushroom after heavy impacts from shocks and low aspect ratio tires. Initially, the shock towers take on a barely visible convex shape, but if compared to the original sheet metal, you'll find the horizontal plane has moved as much as 3/8" upwards, making alignment nearly impossible.
This issue often shows up as a slight pull to the left or right, depending on which strut tower is affected. The M7 Strut Tower Brace's end mounting plates solve this problem by sandwiching the sheet metal and shock top plate, creating a reinforced surface that won't bend, even during hard impacts.
The M7 STB features 1/2" (13mm) thick end plates that add extra strength to the strut towers, preventing mushrooming and potentially costly repairs. The cross brace significantly improves handling by adding torsional stiffness to the front body structure, helping keep your tires planted and pointed in the direction you want to go, especially during hard turns. Machined from billet aluminum and matte black powder coated, the M7 Strut Tower Brace boasts a durable black finish that looks great and won't chip or oxidize.
We have customers who won't drive their new MINI off the lot without one and dealers that sell every new MINI with either the M7 Strut Reinforcement Plates or the M7 Strut Tower Brace.
Concerned about clearance? No worries. The M7 STB profile is designed to clear both stock and aftermarket cold air intakes and ECUs. Its modular design allows easy access to the oil filter or any other accessories that might normally be blocked and require removal of the entire brace.
Installation is a snap (often taking less than 20 minutes)! No need for new nuts—the brace uses the three stock nuts on each side. Installation instructions are available online by clicking the "INSTALLATION" link on this page.
The M7 Strut Reinforcement Plates and the M7 Strut Tower Brace are two separate products that address strut tower mushrooming (you only need one or the other).
If your MINI is mainly a daily driver, the M7 Strut Reinforcement Plates are sufficient. If you have performance driving in mind, the M7 Strut Tower Brace is what you're looking for!

When an E9X is lowered beyond the limits of just lowering springs, the rear wheels toe-in excessively. This excessive rear toe leads to premature wear, that many people attribute to an increase in negative camber. It has become a common belief that an extremely low vehicle will wear the tires wrong as a matter of consequence. It has become standard practice to go as low as you can and proceed to replace your tires every five to ten thousand miles. Whats more is that when the vehicle reaches a certain ride height, the factory arms become maxed out and there is no way to compensate and dial in the proper toe. You're left with an improperly aligned vehicle that is in effect worse off than it was with the stock suspension installed.
This is not only uneconomical but improper and unsafe. ECS Tuning is proud to offer a solution for this problem in the form of Rogue Engineering E9X adjustable rear toe arms. These arms allow for greater toe adjustment on vehicles that have been lowered with a coilover suspension. With the toe set properly the tires can contact the road properly this maximizes grip and minimizes wear.

The MMX Performance adjustable drop links are a great choice for any lowered or hard-driven BMW to zero the pre-load on your anti-roll bar geometry. Plus, by replacing the stock rubber joints with motorsport-spec ball joint ends, you'll add valuable stiffness and precision to handling and steering dynamics.
The sway bar end link attaches the front anti-roll bar ends to the front damper. The OEM links were made the length they are for a reason, to complement the standard ride height.
When your ride height is altered, your vehicle's anti-roll bar ends are pulled up. With around 40mm of adjustable length, plus left and right threaded ends for easy length adjustment, the MMX adjustable sway bar end links allow you to adjust back to zero preload on your anti-roll bar - allowing it to operate exactly as it should once again.
Motorsport-spec ball joint ends using high-strength Teflon-lined steel means a much more direct response when turning into corners. By replacing the soft rubber bushing in the factory links with these motorsport-spec ball joints, cornering and steering responses are immediately sharpened. Importantly, rubber dust boots are fitted to protect the joints from road dirt and salt accumulation.
The lightweight CNC-machined T6-6061 aluminum bodies are anodized in our beautiful MMX gloss black coating to look good and stay looking good.
Features:
Manufactured in the UK from Aircraft grade T6-6061 aluminum billet.
Complete OE replacements
Anodized in signature MMX Gloss black.
Heavy-duty ball joints to ensure a long life span.
325-365mm adjustment range.
Direct replacement – can be used with either factory or Aftermarket rear anti-roll bar, and returned to standard at any time.
Designed with one aim in mind: to help achieve optimum suspension performance and geometric accuracy, and thus increase the effectiveness of your rear anti-roll bar.
Each heavy-duty, high-articulation rear end link attaches the rear anti-roll bar ends to the lower suspension arm. Replacing the failure-prone, weak plastic OEM links with our rigid billet aluminum links greatly reduces flex and allows a sharp, uncompromised transfer of suspension movement through to the sway bar.
As well as the link itself, extra stiffness and precision comes from replacing the flex-prone stock plastic ball joint with motorsport-spec ball joints. An especially valuable upgrade on older, higher mileage car.
