I haven't had much time to play with Boxsters, but did make it to the final race day of the season with North Texas Rallycross. The Frog held together well. My best time was 4th out of 28 drivers, but I had a few runs where I didn't keep the car on the best line and finished 7th overall. The Frog felt good and held together well.
In the off season I plan to get a better setup for the muffler and check over the suspension and alignment to see where I can improve it.
