on the left is original, 650mm. on right is modified, 590mm. 60mm is roughly 2 1/2", or about 1" more than i want, so that should mean that the stub needs to have a length from its base where it threads onto the damper to its shoulder where it contacts the strut mount/bearing of 1". that would mean that with it (the stub) my new length between steering knuckle and mount would be 1 1/2" shorter than stock, resulting in a lowering of the front end by that amount.
heres the rub: a length of 1" (ignore the threads on top for now) is less than the necessary thread depth to screw onto the damper fully...it needs 37mm, and thats just under 1 1/2".
basically, the shortest i can make it from end to shoulder is 41mm; that would leave just 4mm of material above the female threads before the upper shoulder and male threads, the same as the wall thickness. the longest would be 61mm; that would actually duplicate the same ride height its always had, and any more than that and i would be lifting the front end.
thats a maximum lowering of just 20mm. somethings not right...
