BTKUSA F8X/G8X REAR TOE/TRACTION ARMS

$850.00 AUD

 

Take control of your BMW’s rear suspension geometry with the Built to Kill USA Rear Toe Arms with Eccentric Lockout Plates, engineered for precise alignment adjustment and improved stability under demanding driving conditions.

Lowering your BMW or making other suspension changes can significantly affect rear toe and camber. The factory toe arms rely on eccentric adjustment, which provides limited adjustment and can allow alignment settings to shift under heavy loads.

The Built to Kill toe arm system replaces the factory arrangement with fully adjustable arms and eccentric lockout plates, allowing the rear toe setting to be precisely dialled in and securely maintained.

Whether your BMW is built for spirited street driving, drag racing, circuit use or drifting, these arms provide greater control over rear suspension geometry when compared with the factory setup.

Improved Rear Suspension Control

By eliminating the factory rubber bushings and replacing them with high-quality FK heim joints, the toe arms reduce unwanted movement under acceleration, braking and cornering.

The increased adjustment range also allows for more precise rear alignment setup, including optimisation of rear bump steer and anti-squat characteristics for modified vehicles.

CNC Machined 6061-T6 Aluminium Construction

Manufactured in the USA from 6061-T6 aluminium, the arms combine high strength with low weight and are finished with Type III Mil-Spec hard anodising for excellent durability and corrosion resistance.

FK Heim Joints

The adjustable FK heim joints feature:

  • 4130 chromoly bodies
  • Corrosion-resistant black coating
  • 52100 steel balls
  • Hard chrome-plated ball surface
  • PTFE liner
  • 6–24 ft-lb no-load breakaway torque

Eccentric Lockout Plates Included

The included eccentric lockout plates eliminate reliance on the factory eccentric toe adjustment system, providing a more secure and repeatable alignment setup once the desired geometry has been achieved.
