Product Details
This Whiteline Front Strut Tower Brace fits the 2001-2006 BMW 330i 3 Series (E46). Order it as part number KSB557. Whiteline's note for this fit: Exclude models with traction control. Placement: front. Included: 1 strut brace.
A strut tower brace ties the two upper strut mounts together with a rigid bar, so the tops of the front struts cannot flex independently when cornering loads push on the body. Holding them steadier helps keep alignment angles consistent and sharpens turn-in and steering feel.
Installation is rated moderate, with about half an hour of work listed. It does not require a wheel alignment. We also list Adjustable Front Sway Bar Link, Rear Sway Bar Link, and Front Strut Tower Brace Quick Release Kit for the 330i 3 Series.
Features
- Chassis stiffness: Helps keep alignment angles and spring rates consistent by cutting down flex.
- Matched kit: Each part in the kit was picked to suit the vehicle.
- Finish: The polished alloy finish is easy on the eye in the engine bay.
