SPL Parts Adjustable Rear Traction Arms/Links Control Arms for BMW M2 M3 M4 (F87 F80 F82 F83 F8X) - On-Car Adjustable 2024 Aluminium, Titanium Hardware, Made in USA, FK PTFE Spherical Rod Ends - Reduce Wheel Hop/Axle Tramp - RTR F8X

BMW F8x M2 M3 M4 Rear Traction Rods by SPL Parts

Transform the way your F8x drives with SPL Parts rear traction rods. Precision length adjustment lets you dial in rear geometry for sharper response, cleaner launches and repeatable alignment settings for trackdays and fast road. By replacing the soft factory links, these arms curb axle tramp under hard acceleration, calm driveline shudder and add rear-end composure when you lean on the brakes or power out of corners.

Each arm is engineered for strength, low mass and smooth articulation. Gun-drilled 2024 aluminium tubes pair with a 6061-T6 rotating clamp for precise on-car adjustment, while blue anodised titanium socket-head cap screws keep weight down without compromising clamping force. FK three-piece spherical joints with PTFE liners deliver low-friction movement and consistent control under load. Made in the USA and supplied as a matched pair.

What you will feel

• Far less axle tramp for cleaner, quicker getaways and better traction on corner exit
• Greater rear axle confidence under braking and mid-corner, with crisper responses
• Fine-tune anti-squat and bump-steer characteristics to suit your setup and tyres
• Reduced unsprung mass for suspension that reacts faster to bumps and kerbs
• Quiet, precise articulation from motorsport-grade spherical bearings
