Alignment recommendations for street applications


We recommend you set your caster at the maximum positive possible, but make sure both sides are equal. (Slight adjustment may be needed for road crown)


Most street vehicles will achieve good tire wear with -.5 degrees of negative camber. Depending on your driving habits you may need to adjust your camber to compensate for tire wear.


Set toe to the factory specifications
