I do have a digital caliper tool. Maybe I will just stick to measuring from the top shock nut to the bottom. There is limiter/droop specs on the Drake set up sheets that should give me a good starting point. 95mm front and 106.5 rear. Did I really need to spend $8 on the droop gauge that I don't know how to use, well, maybe. When I get to the track in May (when the snow leaves in Canada) I will ask some experienced guys how it works unless I here before then. Come on (Integra) where is your 2 cents on this.
