Whiteline W63620 Rear Lower Inner Control Arm Bushing Kit

The Whiteline W63620 is a high-performance polyurethane bushing kit designed to replace the factory rubber rear lower inner control arm bushings on 2016-2024 Mazda MX-5 Miata (ND chassis) and 2017-2024 Fiat 124 Spider. Engineered for enthusiasts seeking improved suspension performance, these bushings reduce deflection under load while maintaining acceptable NVH levels for street use.

Key Features:

• Precision-molded polyurethane construction for enhanced durability and consistent performance
• Reduces rear suspension compliance and unwanted geometry changes during cornering and braking
• Improves steering response and rear-end stability, particularly during spirited driving
• Direct replacement for OEM rubber bushings with no permanent modifications required
• Designed and manufactured by Whiteline, a leading suspension specialist with decades of motorsport experience
• Includes all necessary bushings and components for both left and right rear lower inner control arm locations

This bushing kit is ideal for drivers looking to sharpen their vehicle's handling characteristics without the harshness of solid bushings. The polyurethane material provides a performance-oriented compromise between the soft factory rubber and metal spherical bearings, making it well-suited for street performance, autocross, and track day applications.
