Thanks for the comments guys. Yes, this track is rather small and has a lot of haripins. Cornering speed is the key on these tracks so I deviated pretty far from stock setup. On top of all the setups, I also shortened the wheel base about 4mm. The front ball diff is so I can go hot into a corner, brake hard, turn, and mash the throttle out. It's fun when I'm being chased by someone and they start to drive at my pace. Most of the guys use a one-way, if they follow me into a turn the way I do, spinning they go. I say it's twitchy because my friends can't drive this car lol. I think it's just fine.
