I had a chance to let a Spec Boxster driver track my car this weekend.
I learned a couple of things that no 911 instructor or Viper instructor or other type car instructor could show me. The Boxster is unique and tracks different from other cars.
He on the other hand, learned the beauty of the Top Speed short shifter. He noticed the difference between our cars immediately and asked about the shifting.
He had a big smile on his face when he said, "I love this, it feels great, it's so different from mine"!
Win - win, I learned faster lines, he enjoyed the quick shifts of my car compared with his race car.
