Two very important lessons were learned at the last autocross. One, it isn’t the best idea to top off your fuel tank before a run; and two, that a modified Doorman gas cap from PepBoys is a bad idea. You know, it smelled a bit like hydrocarbons during one of the runs, and after looking at the photos I can see why. Thank goodness for that hardtop; OE cap is on order immediately.
