all i can say is wow . was running a local point series with my 1/8 e buggy had ran the track many times always had used aka i beams soft with good results . local sweep driver Zachary Arison convinced me to try a set of his tires which were these . i gained over 12 seconds in a five min heat with 5 mistakes made from having more turn in than i had been used to point is i repeat (i gained 12 seconds in a five min run ) thank you zach and thank you sweep for a great tire at a even better price
