My 2016 has been incredible. Nobody for 400 miles has parts but I haven't needed any. Still the fastest thing on the track with just a 13.5. I hardly need to get off the throttle. I was really worried about the car not working on a lower traction surface but its like cheating. I bought the car to run in 1 event over this next summer but I'm going to continue to use it for club racing. Its been the best car I've bought in a while.
