Tim Hardy of Placerville Calif has wheeled with the best on the Rubicon and firmly believes in flat stock springs on SPOA rigs. Tims style of wheeling doesn't allow for high dollar builds or expensive after market bolt ons. He likes stripped down, light weight samuri. He has gone thru more than a few. When I met him a couple years ago I was in the middle of a Calmini bolt on frenzy. I thought he would be impressed with my SPOA shackle reverse, tube bumpers and other frivolous add ons. When asked what he thought of my rig, he said " rip all that crap off and put stock flat springs on it. Drive it off a big rock and roll it over, bust the windows out ( they weigh too much ) put it back on all fours and start wheeling. But then this is from a guy who thinks a locker is welded gears. I left there almost ashamed of my shiney , teal green 88 Sam with all the Calmini stuff. I have since found middle ground where I'm comfortable. My point is, run what you got and don't worry about what others think of your rig.....so, run those flat springs. By the way...this advice comes from a Zook Brother that bought Calmini's v6 Vitara and has 4 Sams in his driveway. One is real pretty...three are not...when I'm smiling...I'm wheeling or I'm under my rig, looking for that middle ground...
