Whiteline Front Lower Control Arm Inner Rear Bushing Caster Kit to Suit Mazda RX-7 FC 4/5 Series 1985-1989
Please note: This Double Offset kit is designed to provide a performance alignment by adding approximately +1.0 degree of caster; a full wheel alignment must be performed immediately after installation to ensure correct handling and tire wear.
Genuine Whiteline Front Control Arm Caster Adjustment Kit. Transform the handling characteristics of your Mazda RX-7 with this premium performance bushing upgrade. The KCA380 kit features Whiteline’s signature synthetic elastomer bushings housed in high-strength, anodized alloy casings. Engineered specifically for the FC Series IV and V, the double-offset design provides a significant increase in static caster and dynamic negative camber. This results in sharper turn-in, improved straight-line stability, and greatly enhanced steering feedback. These bushings are highly resistant to oil, grease, and weathering, ensuring a long service life even under extreme driving conditions. Each kit comes supplied with extreme-pressure molybdenum disulphide grease and internal grease reservoirs for self-lubrication, providing a quiet, maintenance-free operation that outperforms traditional rubber or polyurethane alternatives.
