Just put my Dekagrams on last night, wrapped in BFG Sport Comp 2's 205/50 with stock suspension. I love it so far, I wish the temps would warm up so I can really push them, but so far the car feels much lighter on it's feet, and it's nice to get the winter tires off finally!
Let us HOPE that you did not take off the winter setup too soon (given the screwiness of the weather lately, here on the east coast)!!
