Not much to an alignment, as there is no adjustment for caster or camber with the standard suspension, only toe. I've tried toe in from 0 to 1/16" to 1/8" total, and have settled on 1/16. There wasn't much to notice between 1/16and 1/8, but 0 was definitely more nervous. Given the very stiff springing of these machines combined with their less than stiff chassis, I don't think they have much sensitivity to suspension fine tuning. I use this toe gauge:
