But I recall that before installing mine, the m5 box itself had a bit more than 3.0 turns between locks...but it worked out to exactly 3 turns once installed on the car.
It's an upgrade that I really enjoy...I'm sure you will too.
Interesting - the box I received has just about 3.5 turns between the internal stops, but once installed in the car? hmm. I might have to install to see, I guess..
