Hi guys, looking for some input from anyone that's used Steer and Gear for a new/rebuilt power steering box, and which level of stiffness you have? They list four options: stock(no thanks), then modern, sport, and rally being the stiffest. I'm leaning toward the 'modern' but is it enough of a difference from the one-finger stock feel? If it's only a marginal difference I would just assume go to the sport level. Thanks!
