I've only driven seca twice, it is unnerving to be holding the throttle 100% cresting the main straight hill and down it!
I know sacto could do it half our speed ;)
I need to try the course again, I actually worry about losing the rear end going over the hill portion of the front straight (when the rear end lifts at the top). I need to find the balanced line in that straight..... But I feel comfortable holding it on the back straight up the hill.....
