Dinan Front Thrust Arm / Tension Strut Monoball Kit – Spherical Bearing Lower Control Arm Upgrade – BMW E60 E63 E64 5 & 6 Series incl. M5/M6 (2004-2010) – Brake Judder/Shimmy Fix, Steering Wobble Cure – Radius Rod/Wishbone Bushing Replacement

Dinan Tension Strut Spherical Bearing Conversion for BMW E60 E63 E64

Transform the front axle of your BMW with the Dinan tension strut spherical bearing conversion. This motorsport-inspired upgrade replaces the factory rubber bush in the front radius arm with a precision ball joint housed in a CNC machined aluminium carrier. The result is razor-sharp steering feel, rock-steady braking and a dramatic reduction in brake judder and steering shake at speed. If you are chasing a front end refresh that actually fixes braking vibration, this is the solution enthusiasts trust.

What you will feel

• Instant, precise turn-in with improved on-centre stability and feedback through the wheel.
• Stronger caster control under hard braking for a calmer, straighter car at motorway speeds.
• Significantly reduced high-speed shimmy and braking vibration compared with soft OE bushes.
• Sealed, booted design to keep out grit and moisture for long-term durability on UK roads.
• Minimal NVH for daily driving comfort while delivering serious performance for fast road and track days.
• Machined alloy housings resist deflection for consistent geometry and better tyre contact.

We have fitted and run this upgrade on our own and customer E6x cars at MJ Modifications. Feedback is consistently excellent. Owners report crisper front-end response, more confidence in emergency stops and a noticeable cure for brake judder that used to spoil spirited driving.
