Not if you are doing corner weights AND ride heights - on my race car (running 85mm ride heights to the front sills and 115mm at the rear), it needs to come up on the (lo-rise) hoist, which means settling the suspension again before taking corner weights (again) - corner weighting session can take an hour if we've made a significant setup change which we have to do between going to Winton (short track length, lots of slow/medium speed turns) and Philip Island which is fast (only 3 medium speed turns - the rest a quick to really quick - and the Winton setup at PI is scary dangerous).

The hub-faces are exactly there the wheels are pointing and are as good a reference place to take alignment, camber and caster as the tyre (sorry, tire). arguably better.

I've spoken to a race-buddy who owns a fabrication shop and we might just make our own - I;ve got some bits to trade for his car and he's going to price-up the material (CNC time will be "at marginal cost").

It is worth it to me because getting down onto the garage creeper and up again a dozen or more times in an hour plays merry h3ll with my back.
