Time to buy new Nitto drags. I was talking to a friend I hadn't seen in awhile who has an LS1 M6 car and he is running a set of Sumito tires he bought locally for $89 a piece. He claims that have really good traction and hook great when heated. He even comapred them to a pair of 555R's saying they rank pretty close when warm. Anyone have any expirience with these?
