Another weekend of racing, this time at a 2 day SCCA Divisional autocross event, has taught us a lot about the latest set-up changes to the 2011 Mustang GT we are campaigning in STX class. We’re using this chassis to develop new suspension parts with. We tried out the 265/35/18 Hankook RS3 for the first time, but the new throttle map programming was a FAIL, and I was sideways for most of the weekend. The new “trick” we learned at the last Test-n-tune of up-shifting to a higher gear to avoid wheelspin once again worked, and is our “crutch” until we can get the throttle mapping corrected. You can read more here, and you can also get to the 550+ pictures and 8 in-car videos from this event.
