BMW F2x and F3x Front Thrust Arms with Spherical Bearings - precision caster adjustable links for 2 Series, 3 Series and 4 Series

Transform steering response, braking stability and front-end grip on your BMW with these SPL front thrust arms. Built around FK PTFE-lined spherical rod ends and lightweight CNC machined aluminium links with titanium hardware, this upgrade replaces the soft rubber bushings found in the OE tension struts and delivers repeatable geometry, razor-sharp feedback and confidence on fast road or track.

We run these on our own builds at MJ Modifications and our customers consistently report crisper turn-in, more mid-corner composure and far better feel through the wheel. If you are chasing a front lower control arm forward upgrade for the F2x or F3x chassis, a monoball thrust arm conversion, or a caster adjustable front arm set that tightens up compliance without harshness, this is the kit.

Key performance gains

• Broad caster adjustment window to fine-tune turn-in and straight-line tracking
• Replaces factory rubber with FK spherical bearings for minimal deflection and maximum steering feel
• Anti-dive tuning via supplied stainless spacers for improved braking stability
• Reduced unsprung mass for faster suspension response and better grip over bumps
• Track proven yet road friendly thanks to PTFE-lined, low-friction articulation
