Description
Whiteline KCA495 provides front control arm bushing kit (caster bushing) (KCA495) for 20+ Toyota GR Supra / 19+ BMW Z4.
How It Works
Control arm bushings locate the arm while accommodating its movement. Their compliance affects how closely the suspension maintains its intended alignment as braking, cornering and road loads change. The exact mounting location matters: inner, outer, forward and rearward bushings perform different roles and are not interchangeable simply because they fit the same vehicle.
Key Specifications
- Manufacturer part number: KCA495
- Position: Front
Installation & Selection
Inspect the arm, housing, sleeves and adjacent joints before fitting. Use appropriate support and pressing equipment where required, and follow the specified orientation for offset or shaped bushings. Check alignment after installation, especially when the part changes an alignment adjustment or replaces a deteriorated mounting point.
