Specifications
Part Details:
Running a wider wheel and tire setup, adding wheel spacers, or lowering the car all push rear camber out of the factory adjustment range, leading to uneven tire wear and reduced grip. This Whiteline Adjustable Rear Lower Control Arm kit replaces the fixed factory arms with a complete, adjustable assembly, providing up to 2.5 degrees of camber correction so a proper alignment stays achievable no matter how the car is set up.
Adjustment comes from a cam bolt at the outboard mount and an eccentric bushing at the inboard mount, giving in-field adjustability from both ends. Built from steel with high-grade urethane bushings at just 3.8 pounds per complete arm, they weigh in close to the factory arm while offering far more capability. A rear wheel alignment is required after installation.
