Monoball Suspension Bearings

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.

Watch this Quick Overview

Cartridges install easily to replace rubber bushings for 996/997/Boxster/Cayman. An excellent alternative to our QuickChange Camber Plates for cars that don’t need more camber but still want the handling precision of a spherical bearing monoball. Spherical bearings improve performance. The spherical bearings pivot freely, but eliminate the deflection that is inherent with the factory rubber bushings.

Eliminating Deflection Is Important For Two Reasons

• The factory rubber acts as a spring in series with the strut. This rubber spring-action is completely un-damped and reduces the struts ability to control the tire contact patch. The spherical bearing allows the strut damper to do its job and control the contact patch.
• The factory rubber deflects sideways under cornering loads, causing loss of camber just when you need it most. Our spherical bearings eliminate the deflection, maintaining stable and predictable camber.
