I know the 1/3 rule on VSI 6 modification item 13 (which to ARB and the rest of the public is the 2 " law). Went to the mechanic already for a blue slip and they didn't certify it due to the suspension lift of 4 inches. He said I needed a modification certificate. Called VSCCS and from there I started chasing my tail. If anyone knows a good mechanic that I can take my most precious toy to so I can get a blue slip that would be greatly appreciated.
