I've got a coupon for a $49 alignment and am ready to use it to go change my toe in situation to 0 toe since CivicSIRacer recommended that as a
way to cure to understeer. Since I'm already at 0 toe upfront, it seems I only have to align the rear wheels. Will a minor adjustment from 1/16-inch toe in to 0 toe be enough to make a difference?

CivicSIRacer, would you please explain how running 40PSI upfront and 45PSI in the rear would help with understeer? Is it because the rear tires, being overinflated, would have less grip? I'm currently running 42/36 front/rear and I thought that would be near optimal since the car is FWD.
