I measured 14.3, but because the hub already has less grooves cut in from the original splines it was hard going pulling the new studs with extra splines in. Maybe if I'd used the impact gun it might have been quicker. The big difference was shaving 3mm off the splines less to pull through. Not sure if I'm going to use the spacers though after all this ended up buying Audi 20mm hubcentric spacers for £17 each, CB 57.1 popped them into lathe and bored out to 59.1 got ally spigot rings to adapt from 57.1 to 72.6 wheel side. Not sure I like the fat ass look
