2015 RTL. 18000 miles. BajaRon sway bar. Almost new automobile tires, 17psi F, 20psi R. Had laser wheel alignment. Even on a smooth road, Spyder feels twitchy. Feels like it is jumping around. On cruise control, take right hand of bars and lightly keep left hand on. Still feels twitchy. Is it me, or might something be out of whack?
