I'm always jealous of guys who can predict what size their car will need because it's so consistent or limited.In the picture below, you can actually see that the 11mm is the "heavy duty, non-hollow-shaft, longer" version Wiha and the rest of the set are the shorter hollow shafts. The one to the right of the 13mm is actually a 7mm on a flex shaft. *Perfect* for older Porsche OE hose clamps!!!
The reason both 6 and 7mm nutdrivers are in my pic above is because one air pipe hose clamp on the BMW takes a 6... the other, a 7mm. Otherwise very similar large narrow air pipe screw clamps.
Tonight I read that Gedore thinks you don't need a 14mm? I could have sworn my Golf GTI has some 14mm, but as I've described before at GJ, I think my Golf has everything from 7 to 19mm. Maybe not 9 or 16. (15, but only in bicycle cone wrench.) When I get to work on it I should start a chart.
Also my fleet is varied. Old German stuff, semi-old American dinosaur light truck/heavy SUV, and now, modern tippy Ford van, modern BMW. I like the looks of those flex nutdrivers for hose clamps but wonder how many sizes I need. So far, I haven't had any super cramped approach angles, either. (And I'm that nerd who keeps Rotoclip hose clamps.) I'm sure 911 world is full of OB/GYN-like challenges.
