I'm sure that you have the late SVT type pads and calipers whaich are the same as the non SVT. You can get a good explanation from the BAT site (which might be the same info as you found from shoshop).
www.batinc.net Be aware that the date they show as the changeover date is know to be inaccurate. It was much earlier, perhaps as early as Feburary 98.
The wear limit on the rotor is cast into the rotor near the outer hub face. If you look back a few weeks I posted that figure for someone else. Until you measure the rotor it's anyones guess as to if you have enough material left to machine the rotors.
You posted that the "caliper" does not have any ridge from wear. Did you mean the rotor? If you have that much of a lip, I would say there is a good chance that you will need a rotor.
