Some sportier cars tend to have up to 1 degree of negative camber from stock to give the best handling, one car i know of for sure that is like that is the nissan 300zx... However im not sure if legends are the same way... its always possible... But I know for sure that Legends DO NOT have factory camber adjustment and it would require you buying an aftermarket camber kit to correct it... could it be possible that your struts are wore down so badly that they arent supporting the cars as they should anymore?
