A short, compact, tight autocross track, good for the smaller cars like MRT, UF1, and LX4. The layout looks a little confusing, but it's not bad actually driving it.
Probably wise. The original version was smaller, and it was totally undriveable. The problem is the two 270-degree turns--even now, you have to be sure to get a good line, or you'll hit the wall just due to the minimum turning radius of the cars.
Granted, if you drift it gymkhana-style, this is less of a problem, though I haven't driven the track enough to tell which method is faster. I will say that it's a ton of fun with the LX4, set up with stiff roll bars and really low gear ratios for power-on oversteer.
I'm not sure really. I'm not a great driver, but once I got the hang of it I was turning laps at around 30 seconds in the LX4. I'm sure that could be dropped a fair amount, but since it's such a short track major improvements would still be small time differences. I would guess a truly skilled lap might get 28 seconds.
I'm getting 34-35s in the uf1. I reckon I could cut off at least another second around those 270 degree turns if I had a wheel (gamepads that don't let you max both axis at the same time are no fun, mine hardly lets me touch the throttle at full lock).
