I have had this set of cars on my hd for some time. While I knew there were different versions of the car contained in the mod, I never realized how much care Crossply put in this to mimic the first several seasons of Can-Am. From limited Aero and rather small tires and engines, he built a progression with faster, more powerful and and lighter cars. Combine this with my current fixation with Can-Am tracks and this is about as close as you can get to a Can-Am racing experience. In the workshop, based upon ISI's Howston.
