went to NAPA and they offered only one kind of strut for my mini. it's an MC-40. I'm not sure if there is a different strut for the high performance model. when I went to autozone to price my strut , it only offered a 400.00 billstein strut but they did ask if it was jc works vehicle. so I am m not sure there is a difference in the strut from the 120.00 napa strut and the 400.00 billstein strut in way of the cheap one being proper for the car i own? anyone have any suggestions??
