ECS BMW Suspension Bushings & Mounts for BMW 3 Series E46 (1999-2005)

Clear BMW chassis

Please ensure your correct model is selected

Suspension mounts are designed to absorb the energy of the shocks and springs and isolate road harshness from the chassis. But over time the original rubber mounts will crumble and fail. We have stock mounts and bushings as well as a wide selection of upgraded and heavier-duty for performance street cars. We also offer a full selection of race only bushings and mounts. Simply choose your car below. Included here you will find rear shock tower mounts, front strut mounts, subframe mounts, lower control arm bushings, rear trailing arm bushings, and more.

The ECS Tuning Billet Front Sway Bar Mounting Kit will provide your vehicle with a more rigid mounting solution from the sway bar to chassis than the OEM steel brackets. With an improved sway bar mounting bracket and the included polyurethane sway bar bushings you can expect to achieve an increase in rear sway bar effectiveness and less body roll as a result.

PART DESIGN

The front sway bar mounting brackets are made from a solid piece of 6061-T6 billet aluminum that are precision CNC-machined to bolt into the OEM mounting location while utilizing greaseable, polyurethane bushings. They are Type II black anodized for corrosion protection and include zinc flake coated Class 12.9 alloy steel bolts for premium performance.

The red polyurethane bushings feature a greaseable channel for extended service life and quieter operation than standard polyurethane bushings.

PERFORMANCE FEATURES

Billet & poly mounts replacing the OEM steel & rubber configuration you can expect faster reaction speed and greater effectiveness from your front sway bar due to less deflection. This translates to better handling with sharper, flatter cornering with reduced body roll.

PRODUCT DEVELOPMENT
