the way the rule is officially interpreted in stock classes depends on the car and what the FSM/TSB's say. i don't have the helm's for the 370Z yet, and i haven't been monitoring the TSB's, but if there is an allowance for shims to get camber/caster back within spec, then it would be legal. usually, it just says replace suspension parts, unfortunately. all moot if nissan had put eccentric bolts up front to dial in something b/w -1.5 and -2.0 for camber
