Almost every Stock/Super Stock car in the country is on a radial, unless they are a four speed car. I saw a guy this past weekend at a bracket race with the new M/T bracket radial on his car. I asked about them and he seemed to like it. The Pro Drag radial is fast and hooks good on a fairly well prepped track but 100 passes is about all you will get out of them before they have cords showing. I'm interested to see how many passes the bracket radial will take.
