HA! Was going by the dial! Okay - what's total travel on stock strut? Thanks and I'll never utter another domestic term of measure again!
Total travel? I don't know, but the practical limit is when the top of the body compresses the supplemental spring (aka bump stop) to whatever its limit of compressibility is. And those are the same parts in front for all applications (996.343.301.02), so you aren't probably aren't going to bottom the rod out or anything there because the spring rate of the bumper is approaching 1000 lbs/in as the thing gets compressed to about 1" of overall length.
In the rear, the sport bumper (996.333.105.03) is about 13mm shorter and exhibits about 50% more rate than the non-sport version (996.333.105.02), so it might be a different story there, depending on which bumper you use if you lower the ride height and stay with the non-M030 shock. It seems that there isn't a good compromise there: use the stock bumper w/the non-M030 shock, and you're on it too quickly, or use the M030 bumper with the non-M030 shock, and possibly push the rod too far into the shock body at full bump.
But in any case, the shortened rod is designed to keep the shock working in the sweet spot of its design range, which is a good thing to think about when lowering the car if you intend to actually drive it the way it was meant to be driven.
