The only 1.8 16v that I had much contact with on the race track ( I have had a few Sciroccos on the street ) was Chuck Mathis' ITA car. It was a very competitive car at the time, and while it is ancient history, I don't know of any other VWs that won ITA at ARRC.

We were just talking about different classes a few weeks ago, and were thinking that the 1.8 Golf could probably still be a winner today if prepped right.
