That's not been my experience. For instance, the 2.7t 5 spoke wheel is
listed as fitting on System 1 does not fit over my System 3 without 5mm
spacers, and I've got *maybe* a single mm of space between the outer edge of
the caliper and the inner surface of the rim with the 5mm spacers.

'95.5 S6 avant (System 3)
