I know I dont make a ton of power compared to most of the race cars that run the radial slicks but I will say the 30 x 9 Hoosier radial slick I use hooks pretty good for me most of the time on my local tracks that I run at. Plus I drive on the street on them and even drive to the track on them when I race with them. I only have SS springs as my suspension is nothing fancy at all. But the last 2 times out at local tracks the car ran within 4 hundreths all day long. And at Cecil in Oct 2013 it ran 10.76 three passes in a row as my first pass was 10.81 and then 10.76 three times in a row. And these tracks are just average tracks running local weekend brackets. I was running in the NSS class but it was a new race as it was not a big name group putting the race on. Myself I found as you all know is that as long as I line up in the grove real good these radial slicks will hook good for me almost all the time. But I do understand I am only a 10.70 street car. Ron
