Just wanted to post some quick pictures... more info when I get time
Two bearings (needle + spherical)
Camber and caster adjustable w/o uninstallation
Included rubber-padded upper spring perch to reduce noise
Block height for strut shaft mounting: 1.5"
2.5" ID springs only
These are made to work with race springs only, hence aftermarket struts are needed.
GC does sell versions which allows the use of stock springs. (Edit: may not be the case; please check with GC to verify)
