I had one event on my ZII's a couple weeks back, and I feel that I still have to play around with tire pressures and such. I feel the car performed much better through slaloms and transitioned better.
I have another event this coming Sunday at my usual autocross location, so I should have a better comparison after that event, but so far so good.
