Couple things, those spring spacers are $20-30 on amazon, I got the 1.5's to go along with my OME 912 springs because the 2" spacers were too much with the 912's.

Looks pretty good however I would suggest the front be 1/2" lower then the rear for multiple reasons. A few being: headlight angle, CV angle, handling, and looks :-)

Also just because you do not have vibrations yet does not mean they will not surface, if so just get adjustable lower links easy fix.

Looks great so far! :-)
