Lowering your BMW does wonders for appearance and handling, but it also changes suspension geometry in ways that can hurt performance. As ride height changes, angles between the sway bar, control arms, and axles shift, which can cause binding, poor fitment, and added stress on the factory fixed-length end links. This is especially noticeable on cars equipped with coilover suspension, where slight height differences side to side can preload the sway bar and lead to inconsistent handling.

Our team of dedicated BMW enthusiasts set out to address this common issue with Adjustable Rear Sway Bar End Links. Designed with performance in mind, they offer a fully adjustable range from 100mm to 120mm, helping eliminate preload, restore proper suspension alignment, and improve overall sway bar function. Constructed from high-quality billet aluminum, these end links are built to outlast the factory cast components and are finished with a black anodized coating for excellent corrosion resistance. Laser-etched wrench size markings allow for quick, easy adjustments while installed on the vehicle. Unlike the factory design, these end links use spherical rod ends at the control arm for increased responsiveness and a more direct handling feel. These end links feature a bolt-through bushing design, which is compatible with most adjustable aftermarket sway bars. Mounting hardware is included for easy installation.

Features & Benefits:

Adjustable from 100mm to 120mm Strong 6061-T6 billet aluminum construction Black anodized finish resists corrosion Spherical rod ends improve response and handling feel Polyurethane bushing with knurled bore helps retain grease Fits most aftermarket sway bars with bolt-through attachment Laser-etched markings for quick and easy adjustments

Reinforces the strut towers against deformation while adding valuable triangulation to the front end for sharper, more predictable handling. Designed to prevent “mushrooming” and other distortion caused by rough roads or stiff suspension setups, these plates help maintain consistent suspension geometry by reducing unwanted chassis flex. The result? A more stable, confidence-inspiring front end under load. Strut tower plates are engineered to sit perfectly flush against the towers. If they don’t, it’s a sign the towers have experienced some deformation. In minor cases, this can often be corrected using a block of wood and a hammer to carefully restore the mounting surface.

If you own an E46 3-Series, you're likely well aware that the factory rear coil springs are a notorious weak point. Due to the "Mini Block" barrel design and the elements, the bottom pigtails of the rear springs frequently crack and break, throwing off your alignment, causing uneven tire wear, and ruining your cornering dynamics.
