I have had a 4Point here for quite a while and have sold several. As Peter replied, it comes with a mounting jig for setting the pivot to spindle distance. The spindle to VTA tower distance should be set to 212 mm, and the Kuzma turntables are set up for that mounting distance which makes it an easy drop-in.
A couple of more recent 4Point installations were on an SME 30/2 (a first for Kuzma, but now they make armboards for them so you don't have to pay the exorbitant price from SME for a blank one to machine) and on a Clearaudio Master Reference. On that latter, the 4Point replaced a Graham Phantom (original). Let's just say it took maybe five seconds to hear the difference, and my customer had a huge silly grin on his face.
Among the tools I use, I use the Feickert software, the Pro version, once the basic installation is complete. This is a step which, in my opinion, is crucial to getting the full performance out of the system. Recently I did an alignment on a high end rig in which the owner had used a Fozgometer to set azimuth, the setting for which is where the crosstalk levels are equal -- the curves cross over each other. But he had 52 degrees of phase error at 1 kHz. When my work was complete I had reduced that to 5 degrees and both of us immediately heard the improvements.
