Yes that's something learned. And mix matching parts to get to your goal. I would have never used Calvert and Kim Smith Assains bars together for one. I don't know why I just wouldn't have till now. And that yes you can fo really fast on leafs. He is doing this 4 sec 1/8 on a x275 tire. That's not a big tire at all. 28.5 slick is close to that 275 size.
