Looks great. By lifting 1/2" at the strut you've actually lifted the front end around 1-1/4". Be aware that your factory bumpstops are not long enough to contact the upper a-arm before the strut is fully compressed now. You can blow your struts this way, the strut spacer lifts have a tendency to ruin stock struts. FWIW I added 1/2" to the bottom of the strut above the strut fork for the same reason you did. I've yet to do anything about the bumpstops but I've not bottomed my suspension yet cause I'm a big poser
I think I will just screw a chunk of 1" rubber to the bottom of my bumpstop. Anyway, nice work and innovation
Good luck!
