Sold Each.

Manufactured from high-strength precision-machined aluminium with a durable steel centre sleeve, the solid bushing is engineered to withstand high cornering loads, braking forces and repeated suspension movement without excessive deflection. The eccentric centre design allows accurate suspension geometry adjustment while maintaining secure location of the lower control arm. Designed for direct OE-style installation, it is ideal for performance upgrades, motorsport applications and suspension rebuilds.

What This Product Does:

• Secures the lower control arm to the suspension mounting point.
• Reduces suspension flex under load.
• Maintains more accurate wheel alignment.
• Improves steering precision and front-end response.
• Supports consistent suspension geometry during braking and cornering.
• Provides an eccentric centre for suspension alignment adjustment.
• Restores precise suspension operation.
• Forms an essential part of the front suspension system.

Symptoms Of Wear Or Failure:

• Knocking or clunking noises from the front suspension.
• Excessive movement of the control arm.
• Uneven or accelerated tyre wear.
• Poor wheel alignment.
• Vague or inconsistent steering feel.
• Vehicle wandering under braking or acceleration.
• Cracked, split or deteriorated original rubber bushes.
• Excessive suspension deflection.
• Reduced handling precision.
• MOT or vehicle inspection failure due to worn suspension bushes.

Why Replacement Matters:

• The original lower control arm bushes are subjected to constant braking forces, cornering loads, road impacts and engine vibration. Over time, the rubber material can soften, crack or separate from its housing, allowing unwanted movement that affects suspension geometry and steering accuracy.
• Replacing worn bushes with a solid eccentric centre bushing significantly reduces suspension deflection, allowing the suspension to maintain more consistent alignment under load. This results in sharper steering response, improved braking stability and more predictable handling, particularly on performance-oriented or track-driven vehicles.
• The OE Match Lower Control Arm Eccentric Centre Solid Bushing is manufactured from premium-quality materials to provide factory-style fitment, exceptional strength and long-lasting durability. It is the ideal solution for Porsche suspension upgrades, performance driving, motorsport preparation and professional suspension rebuilds.

Our Eccentric Control Arm Monoball Cartridges replace inner rubber bushings with spherical bearings, providing low friction and precisely holding camber settings.
The eccentric design allows increasing or decreasing camber, as needed.

Increasing Camber

Position the eccentric to maximize Lower Wishbone length, adding about .86 degree of negative camber on the 996/997 rear suspension, about .36 degree of negative camber on the Boxster rear suspension, and .39 degrees on the 996/997/Boxster front suspension.
Cost effective for cars that just want extra camber. For even more camber and ease of adjustment, see our GT3 type fully adjustable control arms.

Decreasing Camber

Position the eccentric to minimize Lower Wishbone length. Perfect for lowered cars that have too much negative camber and want to get back to factory camber settings to minimize tire wear on the street. Makes rear camber about .86 degrees more positive & front camber about .39 degrees positive for 996/997 while Boxsters will get about .39 degrees positive front and .36 degrees positive rear.



Made from hardened steel, plated and weather-sealed, these bearings are made to last. Fits the front or rear stock and GT3 type control arms.

Sized to fit factory original control arms. Not compatible with some aftermarket replacement control arms that use a larger non-stock size bushing.
