Description
Whiteline Front Radius Arm – 2019-2021 BMW Z4 / 20-22 Toyota GR Supra — Static alignment is only useful if the suspension can hold those relationships when the tire is loaded. This product is listed for 2019-2021 BMW Z4 / 20-22 Toyota GR Supra.
A suspension arm locates the wheel through its travel. Reducing unwanted compliance at that point helps toe, camber and wheel position remain more consistent as braking and cornering loads build, which is why arm condition and joint design matter on both street and track setups.
Technical Overview
- Position: Front
- Application: 2019-2021 BMW Z4 / 20-22 Toyota GR Supra
- Whiteline part number: KCA495
Who This Is For
Useful when the OE arm or joints are worn, when additional geometry/alignment capability is required, or when a performance build needs more consistent wheel location under load.
Installation & Setup
Plan for an alignment whenever installation disturbs or changes a wheel-locating point. Final tightening procedures should follow Whiteline and vehicle-manufacturer instructions, particularly where bushings are designed to be torqued at normal ride height.
