Fine-tuning your coilover damping shouldn’t 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

A smart upgrade for track cars, daily drivers, or anyone who values easy access to suspension tuning, without compromising interior fit and finish.

Dramatically improve performance and aesthetics with an average lowering up to 1.4" front and rear.

Take your F3x to the next level with upgraded performance and aesthetic. ECS lowering springs are specifically designed with both handling and comfort in mind for the best mix or performance and drivability. With an average lowering range of 1.0"-1.4" you have the added benefit of lower center of gravity providing superior cornering and better steering feedback. Lowering springs not only increase handling performance they provide an astounding aesthetic upgrade by decreasing the wheel gap and giving your car a more planted/fitted appearance.

FEATURES AND DESIGN:

MADE IN THE USA
Average lowering of 1.0" to 1.4"
Front spring rate: 184 lbs/in
Rear spring rate: 462 lbs/in
Lowered center of gravity
Linear style springs
Black powder coating with red ECS logo
Designed specifically for your chassis these F3x lowering springs feature a linear style spring similar to a coilover. The issue with coilovers is the rough ride due to a drastic drop and much higher spring rates. When you have higher spring rate like coilovers it takes much more force to compress the spring which leads to a much more rigid ride. ECS lowering springs provide a happy medium between the factory suspension and coilover suspension. These springs are stiffer than factory but softer than a coilover spring to achieve the balance of increased performance and aesthetics while retaining a comfortable ride.

What is spring rate?
​You may ask yourself "what is the spring rate and how does it affect my ride?" Spring rate is the amount of force needed to compress a spring one inch. For example if you have a spring rate of 300lbs per inch it will take 300lbs of force to compress the spring one inch. An average coilover for your F3x has over 400 lbs/in for the front and over 500 lbs/in for the rear, this means that it will take over 400lbs of force to compress your front spring one inch and over 500lbs of force to compress the rear one inch. The higher the spring rate, the more rigid your ride is going to be. ECS lowering springs for your F3x have a spring rate of 184 lbs/in in the front and 462 lbs/in, an increase over factory but much less than a coilover. You can now both understand and explain the benefits of lowering springs to find the best solution for you.

Upgrade your BMW's suspension with ECS Tuning Adjustable Sway Bar End Links, designed to provide up to 60mm (2.36") of adjustability. These end links allow you to eliminate sway bar preload or fine-tune it for specific racing needs and corner balancing. When installed, they improve drivetrain clearance and enhance sway bar responsiveness by reducing deflection, ensuring superior handling. Perfect for lowered vehicles using springs, coilovers, or air-ride suspension systems, these adjustable sway bar end links allow you to remove unwanted preload caused by changes in the center-to-center distance between sway bar mounting points. By adjusting the end links to a neutral position, you eliminate sway bar preload, enhancing suspension performance in various driving conditions.

The main body of the ECS Sway Bar End Links is crafted from strong, lightweight 6061-T6 billet aluminum and anodized red for superior corrosion resistance. Featuring left and right-hand threaded center sections and machined hex wrench fittings, these end links allow for quick and easy on-the-car adjustments. Zinc-plated hardware ensures secure and lasting adjustments, while the heavy-duty ball joint ends come with weather-resistant rubber boots and stainless steel wire retainers, providing superior protection against salt, rain, and ozone for extended durability. Each kit also includes zinc-plated Nyloc nuts and hardened steel washers for secure installation and improved contact surface on the sway bar.

These end links are designed, engineered, and rigorously tested by ECS Tuning to ensure the highest quality. Whether you have a lowered or stock suspension, these adjustable sway bar end links are the perfect upgrade, offering a high-quality, heavy-duty replacement that fits your specific needs.

Features:

Range of Adjustment: 255mm (10") to 315mm (12.4") 6061-T6 Billet Aluminum Construction: Red anodized for superior corrosion resistance Zinc-Plated Hardware: Provides durability and superior corrosion protection Right and Left-Hand Threaded Center Sections: Quick and simple on-the-car adjustments Heavy-Duty Ball Joints (M10x1.5): Weather-resistant rubber boots and stainless steel wire retainers for long-lasting durability NOTE: If you've modified your vehicle's suspension with aftermarket struts or coilovers, the mounting location for the sway bar end link may have moved. To confirm fitment with our adjustable end links, please measure the distance between the sway bar and the mounting location on the strut body with the vehicle at ride height and confirm that it is within the 255 mm - 315mm range of adjustment.

Replacing your struts and shocks? Don't forget the bushings! The rubber mounts for the shocks will go bad over time, especially if you drive hard or the roads are particularly rough. The shock mounts locate the front struts and rear shocks to the car - providing a quiet and vibration-free buffer between the road and the cabin. Shock mounts and bushings can wear out just like any other rubber part on the car. This leads to more noise and harshness reaching the chassis and may complicate your new suspension install. When installing new shocks, that is the perfect time to also replace the mounts. There is no additional time to install them, no special tools required, and doesn't take any extra time! If you re-use the original mounts you have the risk of them failing before your next shock replacement, doubling your labor costs.
