Ohlins forks on S4 is difficult, you’d need 15mm offset, 6 hole mounted disks which AFAIK is only 998R. Every other Ducati with 15mm offset discs has a 5 hole mounting, which is much easier to find.

It should be fairly obvious if they’re 5mm out when you look at them through the ~25mm slot in the top of a caliper. I’m not as familiar with 696/796/1100 specs, they may not have the same differences.

edit: since you won’t have monobloc calipers it’ll be really obvious, the centre line of the disc should be lined up with the join running down the caliper.
