Construction & Design

The SPL Parts Bushings feature a robust construction utilizing high-grade materials designed for performance and longevity. The core of each bushing is a massive 1" FK Racing Bearing, which is self-lubricating thanks to Teflon liners that reduce friction and wear over time. The spherical bearing design replaces the stock rubber bushings, offering a more direct and responsive connection that translates to improved steering feel and handling precision.

The bushings are engineered with precision CNC machining to ensure perfect fitment and alignment. Their durable construction withstands the stresses of aggressive driving, track days, and everyday use, making them a reliable upgrade for your vehicle's suspension system. The design also helps maintain suspension geometry under load, which is critical for consistent handling and braking performance.

Performance & Handling

Installing these SPL Parts Bushings results in a noticeable improvement in your BMW Z4's handling characteristics. Expect sharper turn-in, reduced understeer, and enhanced steering feedback. The spherical bearings eliminate bushing deflection, allowing your suspension to respond more accurately to driver inputs.
