Just had my UR Crank Pulley installed yesterday and all I have to say is WOW! I remember we were discussing this in another post a while ago. I don't know if you did get a chance to do this mod yet but it is well worth it. I can feel the difference in normal driving and spirited driving. The car just feels more responsive and more peppy throughout the whole RPM band. 7lbs off the crank is HUGE.
