For used tires following changes: std rear hex, 4.0 rear droop, diff and spool down, 1.5 front camber, 1.25 toe out. NOTE: This tires worked very different from what I ever had before. Maybe next time all will be different again. Tires felt like inbetween the MOD and STOCK version wich we had before. For heating... 45min with paper reapply many times and then 5min with freh paper to dry them
