Two versions are available to choose from. The Club Sport design is fully compatible with all shock kits that are designed to work 
with OEM mounts. This includes PSS10, KW and the OEM struts and springs. The Race designed is designed  to use  to use 
with race style coil over kits like JRZ, Moton, MCS, AST. GT3 & the GT3 Cup struts.
Offset mounting holes increase the  camber adjustment range by 1.1 degree. The compliant factory rubber bushing is replaced with a large precision Teflon-lined spherical bearing for reduced camber changes, increased suspension feedback, quicker steering response, and better handling. The spherical bearing is made to our specific specifications, and will not wear out and rattle like others on the  market. The housing is CNC machined from 6061-T6 aluminum billet, providing high-strength, light weight, and a perfect match to the factory mounting surface. The spherical bearing is securely clamped into the billet housing.  
The Club Sport design distributes the spring load on the housing, not the monoball, for increased monoball life.
