Our GT3 Cup Inner Lower Control Arms uses weather sealed spherical bearings. These deliver superior precision, control, and performance. They will transmit a bit more road noise than rubber bushings.
Spherical bearings further improve performance. The spherical bearings pivot freely, but eliminate the deflection that is inherent with the factory rubber bushings. This 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.
