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(M12x1.5): Weather-resistant rubber boots and stainless steel wire retainers for long-lasting durability

The rear lower control arms on E82/E9X models are the weakest link in the rear suspension. The arm is made from folded sheetmetal and it bends and deforms easily. Not only will it deform from potholes and curbs, tow truck drivers love to hook onto them without realizing how weak they are. We have seen other race teams complete the box section to make them stronger. A bent arm will throw off the geometry in the suspension, potentially affecting handling and tire wear. These aluminum arms are both lighter and stronger than the factory sheetmetal arms and is the best solution for chronic bending of the stock arm. These are a direct replacement to your stock arms with no changes needed to your alignment. New high-grade hardware is included.

Note: the stock arm is designed from the factory to be intentionally weak. These arms will bend so that something else in the suspension does not break. Our race cars used the stock sheetmetal arm but we replaced them often. We found that it was better to finish a race with a bent arm than not finish due to a catastrophic failure. The ECS arms are still designed to be the weakest link but are far stronger than the factory arm and will not bend as easily.

This item fits the following BMWs:

2008-2013 E82 E88 BMW 128i 135i 1M Coupe

ECS Polyurethane Subframe bushings are ideal for street driven vehicles and those that see occasional autocross or track time. Featuring 95A durometer polyurethane, ECS Polyurethane Subframe bushings are 25% stiffer than street bushings. Engineered to perform, ECS Polyurethane Subframe bushings offer a supreme level of control, while still maintaining enough comfort for the street. Expect improved steering feel, turn in, more responsive handling and overall improved chassis composure.

Key Benefits:

95A Polyurethane isolator reduces unwanted drivetrain movement while still allowing for an aggressive yet streetable driving experience.

Polyurethane bushings reduce subframe bushing deflection versus stock rubber bushings while keeping vibrations associated with such modification to a minimum.

Poly formulation and durometer, profile, and loaded surface area designed to minimize stress concentrations to stay within acceptable compressive strain limits of the material

Tasked with keeping the vehicles rear end firmly mounted while absorbing noise, vibration, and harshness (NVH) ECS Polyurethane Subframe bushings were engineered to provide a balance of control while making ride quality more responsive, yet still streetable. As a factory bushings age, they become brittle and begin to harden and crack. When this happens the bushing will actually shrink and allow excess play, or movement in the subframe. This is typically felt by a sudden jerk or "thunking" noise under acceleration and is a leading cause of "sloppy" or "loose" suspension feel. By replacing the bushings with full polyurethane this play is eliminated since the subframe is being held in place by a much stiffer material that will not harden or shrink over time. Additionally, the inherent stiffness of the urethane material translates body forces much more directly. This means steering and acceleration inputs from the driver are effectively transferred to the wheels and vital road information is transmitted properly from the wheels to the driver.

Looking to improve your car's handling in the corners? ECS Tuning's rear non-adjustable sway bar is a cost-effective way to limit body roll and keep your wheels planted when entering a corner at higher speeds. Sway bars are a great way to improve handling without sacrificing ride quality or reliability! Sway bars are typically sold as a front and rear set to balance the handling. But a rear sway bar only can also have excellent benefits, especially on a street car. Going with a larger rear bar will improve steering and handling even at low-moderate speeds. ECS has specified a 15mm sway bar that has been fine-tuned for use on the E9X and E82 models. Urethane bushings with a reinforced inner core that requires no lubrication are included.

The ECS Strut Tower Bar Kit in striking wrinkle black finish goes beyond aesthetics - it offers essential functionality. This kit significantly reduces chassis flex, contributing to a stiffer suspension setup. Moreover, it plays a crucial role in triangulating the front end, resulting in more consistent suspension geometry that enhances your vehicle's performance.

It's essential to ensure that the strut tower plates sit flush against the strut towers. Any misalignment may indicate minor deformations in your strut towers. However, this can be easily addressed using a block of wood and a hammer to reinstate the ideal alignment.

The polished aluminum ECS strut tower bar kit offers more than just good looks - it reduces chassis flex to stiffen the suspension, and helps to triangulate the front end, providing more consistent suspension geometry.

Strut tower plates should sit flush against the strut towers. If this is not the case, your strut towers are to some extent deformed. This can be easily remedied in minor cases with a block of wood and a hammer.

This carbon fiber strut brace uses a flat-oval design with a hinge-less mounting system that makes this one of the best strut braces on the market (especially at the price!). Cornering forces can put stress on the chassis, especially when used with stickier tires and stiffer suspensions.Strut braces help to reduce chassis flex by tying the two strut towers together. This design is stronger than most strut braces that use a hinge on the end that allows additonal flex. This design has fixed end mounts that the strut bar is bolted to. The slim oval tube is 100% carbon fiber for excellent strength and rigidty. The entire assembly is less than 5lbs and installs in minutes.

Fitment note: the end plates on this brace are closed. Some aftermarket front struts have an extra tall strut pin that will interfere with this brace.

This item fits the following BMWs:
2006-2011 E90 BMW 325i 325xi 328i 328xi 330i 330xi - Sedan

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.
