Had the most fun day of my life with it.
This was the best autocross course that I have ever driven and I wish it would never end. I drove my car today for about 80+ tracks on my MP3.
We got 8 runs on the competition course and 20+ on the practice/fun run course. I ended up switching cars with about 4 people and it was awesome. My brothers car is ridiculously fun to drive, especially now that we disabled the front subframe (which does nothing but add 40lbs). I switched cars with an S2000 on race tires and it was night and day with the difference that they make. I was almost full throttle on the whole course, including a turn-around, and they would not budge.
This is what happens when you hit a cone at 6.8k in 2nd gear. (Dunno exact speed)
Totally worth it. To my defense, it was raining.
