In 2009 while i was stationed in Yakima, WA i went to a 4x4 offroad meet in the dead of winter, theres a hill that these guys were all trying to climb that's abotu half a mile to the top through 2.5ft of snow with ice underneath it, with 1.25in spacers nokian hakka pelitta studs and a slightly modded sti i figured sweet a hill.
Guy in 77' lifted ford f-250: "you should take that little thing home before you break it"
me "bet i reach the top and u get stuck"
ford-"no way tht thing makes it even close to the top u need locking hubs, and four wheel drive to even attempt it"
me " i'll send you a postcard from the top"
30mins later i was up, 50/50 lock engaged kept it in 2nd gear and made it to the top with no problem, f250 got stock 1/4 of the way up.
