Just got the 5100 set of 4 from USA, ordered Monday, here in Perth Friday. Used e shock.com aka DonsSports.com Michigan. Cost $481 with the airfreight being $140 of that. Plan on Dobinson springs all round, LD 35mm lift on rear and 10mm lift on front with 2nd slot from bottom on the shock, giving 35mm or so. Super cheap autos supplying the dobinsons kit for $900ish. Have the Nissan winch bar on front without winch, getting the underbody plates, has arb canopy, but mainly unladen or light loaded. Wanted touring and town comfort/control so didn't want it raised too much. Will advise on the results. Put the back 5100s on last night with the original springs, old original shocks (108K) were now only half full of oil, no wonder the back end used to wander around...
