Product Description

The SuperPro SPF4623-80K Front Lower Control Arm Inner/Forward Bush Kit is engineered specifically for the Mazda RX-7 (FD generation, 1992-99). Over time, the factory rubber bushes in this critical mounting location can degrade, allowing excess control-arm movement, disrupted alignment under load and uneven tyre wear. This upgrade restores firm, precise mounting with advanced polyurethane bushings that resist deformation and wear.

Manufactured by SuperPro using their proprietary polyurethane compound, this kit offers significantly improved durability compared to standard rubber bushes while maintaining ride comfort and reducing NVH. Installation follows the original mounting points - no cutting or welding required - though a full front wheel alignment is strongly recommended after installation to ensure optimal suspension geometry and maximise tyre life. Ideal for vehicle owners focused on performance, longevity and sharper handling.
