I did go to the HB web site and downloaded the manual. I wanted to take a close up look and to my suprise, several small changes can be seen. It appears to me that the suspension arms are braced better and they are offering the hockey stick tie-rod ends.Fuel tank and lid changes as well. Nothing major but changes are on the car that really aren't listed.
They pretty much built the same car that most of us racers have been driving the past year.
