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: 215mm (8.46") to 275mm (10.82") 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

A very common weak point on the 3 series BMW is the sheetmetal of the rear shock tower. The sheetmetal here is relatively thin and very susceptible to stress and fatigue. A worn out shock will bottom-out more often and this energy is transferred through the bump stop and into the metal chassis. Stiffer shocks and shock mounts also put more stress on the sheetmetal. Factor in age, mileage, and environmental conditions and it's not a surprise that we see shock tower failures often. BMW addressed this issue with reinforcements of their own but our's are thicker for additional strength. This kit mounts on top of the shock tower and can either be bolted or welded in place. Because of the shape of the rear shock tower, these do not fit cabrio/convertible cars.

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

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.

These rubber bushings from Meyle are a direct replacement for the stock differential bushings in the E46 3-series, E83 X3 SAV, and Z4 Roadster. If your original bushings are worn (likely around 100,000 miles) these are a great replacement upgrade. The front bushings are the stock OEM type rubber bushings. The rear bushing is a Meyle HD upgrade over stock - about 15% stiffer than the originals. This means the bushing will not flex and twist as much. This puts more power to the wheels since power is no longer used up for 'torquing' the bushing. These are not race bushings; the rubber material is perfectly suitable for street use.

The non-M E46/E83/Z4 models use three differential mounts - two front bushings in the subframe and one rear mount in the diff cover. This set of bushings covers all three. You can opt to include new mounting hardware in the Options list below.
