| Huge differences. I chose Powertrix arms for both my Zs over all the other brands based on the specific designs/specs and features that are unique to the Powertrix design. IMO its definitely by far the best camber arm for the Z32 These are the major points for my decision: 1. Koyo SEALED ball bearings
2. proper specs and mesurements for the components of the arms specific to the Z32.
2. Strengthed Reniforced collars
3. Center support shaft that eliminates unwanted stress on the bearings. Here is a tech info directly form Powertrix.
