On one of My runs to Sun Valley, Idaho, a 600 mile trip, there is a 121 mile segment in Eastern Washington that is very rough. On the way to Sun Valley My +8 had Koni's on soft. In Sum Valley My +8 would be idle as I was driving a 2000 +8 of My Friends to Northern California and Back. I ordered a pair of Rutherford AVO's from Morgan Spares to be delivered in Sun Valley. The back shocks were already AVO's. After replacing the Koni's with AVO's I drove back to Seattle on the same route. the 121 mile segment was much improved and I maintained a higher speed with the AVO's. Still on Soft. I have not experimented with the adjustment.
