The R6’s are the road racing compound. They take longer to get hot (stickey) since they are made to last doing several 20-30 min sessions on end. The Hoosier A6’s are the softer compound since they are for autox and don’t have to work nearly as long, however they have to be sticky right off the bat since they don’t have much time to warm up.

Honestly for drag I dunno how those tires would do, they have pretty stiff sidewalls for cornering purposes. Even taking lots of air outta them might not get the same effect as a purpose built drag tire. Its your call, but I figured I’d toss some info on them your way since I see people with these tires every weekend :bigthumb:
