Normal Mazda 6. I did however use a old Protoform Alfa 156 during most of the last season in our 13T blinky, finishing 2nd overall in the championship. I found the body to be superior on fast tracks because in my opinion it created less drag then others. On technical tracks I used a HB Subaru Impreza Type B. I didn't try these bodies on my new car in boosted 10,5T since the Alfa is now a shelf queen and the color started to peel of the Subaru almost from the beginning- now it is in a horrible state
