Turner Motorsport Thrust Arm Monoball Upgrade Pre-Installed Arms - E60/E63/E64

Transform the front end of your BMW with pre-assembled spherical bearing tension strut arms for E60, E63 and E64 models. Sharper turn-in, rock-solid braking and laser-precise road feel without the squish of standard hydrobushes.

Factory fluid-filled bushes are known to soften and split, which leads to steering shake under braking, vague feedback and uneven tyre wear. These upgraded forward lower arms arrive ready to bolt on, with a precision spherical joint in place of the stock rubber inserts. The result is crisp response, stable geometry and confidence-inspiring control for fast road and track day use, while remaining civil for daily driving.

• Pre-built arms for a true bolt-on install. No pressing, no faff.
• Sealed, pre-greased genuine BMW ball joint at the core for long service life.
• CNC machined 6061-T6 anodised aluminium housing for strength and corrosion resistance.
• Knurled outer surface for an exact interference fit and durability.
• 304 stainless steel bearing inserts for precise alignment and smooth articulation.
• Low-friction movement with no binding. Minimal NVH for a road-friendly upgrade.
• Eliminates brake judder, steering wobble and tramlining commonly found on tired front ends.
• Improves braking stability, steering accuracy and tyre wear consistency.

Why enthusiasts choose this setup:

• Instant steering response and confidence on B-roads and motorways.
• Superior feedback compared to conventional rubber or liquid-filled bushes.
• Ideal for spirited driving and track work, yet perfectly usable every day.
• We run these on our own cars and customers have been thrilled with the transformation.
