Thanks guys. Yes I run the 3400 lb SS springs I bought from Mancini. I use the longer ext shocks from MP and there is no adjustment on them. All other suspension is stock other then the Comp 3 way front shocks. Its not killer but I guess its ok for a street car on the Hoosier 30 x 9 radial slicks. I use a Dynamic 9.5 converter and its best is 10.76 @ 125 with a 1.50 best 60. On normal days it runs 10.80's @ 124 with the 60 between 1.50 to 1.53 Myself I love the radial slicks since I run radials up front and I drive on the street all the time on them. The car handles great with radials on all 4 corners as I will never go back to bias tires. Ron
