The Audi has less compression, less cam , more front weight. If it is faster than the Golf, Than something got missed. Did SCCA ever get a real cam for those?? .
Evry time the rules change to take more stuff out, we have to go and lower the Cg, move the # to the rear, etc. Constant obsession for weight management.
Give the cars with wind up front windows a 50# weight break.
