That looks a little primative, and most likely pretty inaccurate.

If you check with autoX guys and racer suppliers they should know which gauges to recommend as a lot of those people do their own alignments.

The main thing is the Z33 in stock form doesnt have that much room for adjustment which is why they benefit well from adjustable links and eccentric bolts.
