Fine-tuning your coilover damping shouldnt mean stripping out your rear seats or interior panels. On many applications, rear shock adjusters are hidden behind carpet, trim, or seatbacks, making quick adjustments a hassle.
The ECS Rear Damping Extension Kit solves that problem with a clean and functional solution. These flexible extensions relocate the adjustment knobs to an easily accessible point above the rear shock towers, letting you dial in your suspension from inside the cabin, no disassembly required.
Installation is straightforward: simply drill a small access hole in your interior trim and route the extension cables through. The adjustment knobs can be removed to allow the line to pass through smaller openings, minimizing cutting. For proper installation, be sure to fully loosen the set screw, insert the cable, then securely tighten it using the provided Allen key.
Kit Includes:
(2) Rear damping adjuster extension cables
Installation hardware and Allen key
A smart upgrade for track cars, daily drivers, or anyone who values easy access to suspension tuning, without compromising interior fit and finish.

You get the best of both worlds with this pair of Turner Motorsport adjustable sway bar links. We searched far and wide to find the hidden gem of swaybar links. You get the same quiet operation and long life as the stock links plus the strength and adjustability of rod-end style sway bar links.
With the wide range of suspensions and sway bars available today adjustable sway bar links can help you with many problems. Along with the ability to remove preload you can change the length to maximize sway bar geometry. Example: if the sway bar hoop comes too close to the steering rack, oil cooler, or under tray in its suspension travel you can adjust it by simply lengthening or shorting the adjustment rod. In some cases you may need a longer or shorter adjustment rod to achieve optimal geometry. We also offer these same links in other custom lengths (click here) that may not be specific to BMW chassis.
Features:
Turner Swaybar Link Specs:
TSU9912AF1: 220.00mm - 235.00mm / 8.66" - 9.25"
TSU4612AF3: 250.00mm - 265.00mm / 9.84" - 10.43"
TSU5012AF8: 280.00mm - 295.00mm / 11.02" - 11.61"
TSU9912A95: 290.00mm - 305.00mm / 11.42" - 12.00"
These adjustable sway bar end links can be used on a variety of BMWs. Please select your car below. Please note these end links do not fit non-M E36, except 325i/is produced before 6/1992.
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!
