Justin, dad's 08 d8 is running good, broke the primary clutch spring, other than that it is kicking butt (600 miles so far this season on setup). Just got an 09 d8 1 month ago, shoot some #'s to me for mine. Really hard to ride stock when you get off a turbo sled, I've been ruined for sure! Trying to talk others into letting me install more, tell me about the group buy deal. Thanks again for the top notch service!
