Hi, I need to adjust toe and camber on the rear of my scirocco, and I had been using the "blue adjusters", but every time I take them off I find that the (nylon?) blue part is broken (torn) in one or more places. Are there alternatives? I think I saw some supplier that has steel shims that adjust camber only, but what if I need to adjust toe as well? I was thinking that you could use high-quality hard washers between the stub axle and the trailing arm...
