Turner Motorsport Spherical Bearing FCAB/Monoball Front Control Arm Bushing Kit - BMW E36 (incl. M3), E30 3-Series, Z3 - Wishbone Bush Anti-Deflection Upgrade, Rose Joint Front Lower Arm Rear Bush

Ultimate spherical wishbone bush kit for BMW 3 Series and Z3 - sharper steering, stronger braking, zero mush

Looking for a serious front axle upgrade for your BMW without the harshness of solid mounts? This Turner spherical bearing conversion replaces the factory rubber front lower arm rear mount and transforms steering feel, turn-in and braking stability. It is a direct-fit, serviceable and greaseable bearing solution that delivers precise, predictable handling on fast-road and track day cars while remaining daily-drivable.

Stock front wishbone bushes allow the wheel to move fore and aft, which soaks up bumps but also dulls response and can cause shimmy and clunks as they age. This kit swaps the compliant rubber for a sealed, low-friction spherical joint in a beautifully machined housing, eliminating unwanted deflection for laser-accurate control and confidence under braking.

Why enthusiasts choose this spherical FCAB upgrade

• Instant steering response and crisp turn-in - no vague on-centre feel
• Rock-solid braking stability and improved pedal feedback
• Minimal increase in cabin noise or vibration compared with solid metal mounts
• Direct press-in fit to the OE carrier - no cutting or fabrication
• Greaseable and rebuildable for long service life
• Integrated double-lip seals keep dirt and moisture out for durability

Engineered for performance and longevity

• Robust sealed spherical bearing - rated for heavy dynamic and static loads
• 6061-T6 anodised aluminium housing with grease nipple for easy maintenance
• Precision CNC Delrin arm adapter for a tight, slop-free interface
• Knurled outer profile for a secure interference fit across a range of carriers
• Low-friction, bind-free movement to maintain geometry under cornering and braking

Real-world results

We have installed this kit on our own builds and customer cars. Feedback is consistently the same - sharper front-end bite, better mid-corner stability and a noticeable reduction in tramlining and shimmy from tired rubber. It is a proper performance suspension upgrade for anyone chasing E36 or Z3 handling precision without turning the road car into a rattly track special.

Maintenance

• Grease before installation and at each oil service interval with a high-quality moly grease
• Inspect dust seals periodically to ensure contaminants stay out
