12mm Macht Schnell spacers installed on the rear. Much better stance now although 15 or 18mm would have cleared and have been more agressive. I'm happy with the stance and it sits 2-5mm more out than the fronts. I did some aggressive driving on empty wet country roads today and wowee are these tires super controllable. I was able to drift in lane with excellent throttle oversteer control. I also took it up to 120 on open freeway and it was a walk in the park. Very confidence inspiring and I am loving these tires for wet use.
