i owned the red one. i helped build the white one.
i didnt have problems getting the bolts in, but i did have problems in that the bushings were too wide, and i actually had to grind the bushings down so the shackle would slide over the bushing.. a "low profile" bushing would have been ideal...
on the rear hanger, i did have to grind out some of the stock hanger for the bushing to clear. the bushing and the hanger were trying to occupy the same space, so i had to make room for the bushing without it getting chewed up.
other than everything being very tight fitting, i had no other issues.
