I use the Hoosier 30 x 9 radial slicks myself. I found that as long as I stage in the grove where all the cars launch it always hooks fine. My suspension is basically all stock other then 3400 SS springs and Comp 90/10 front shocks. Rear shocks are just the longer MP shocks. My 60's are low 1.50's as its usually from 1.50 to 1.52 with a 1.50 best. But is is very consisdent for a radial slick on a car I drive to the track. The last two times at the track all my passes were all within 4 hundreths of each other all day long. Ron
