It's coming along very well. For instance, for some reason, I was doing embarassingly bad in the XRT yesterday (my laps were 4 seconds off my regular laps. o.O), but then I had a FOX duel with someone at BL and won all the 3 races to make up for the XRT fiasco. I only need to cut about one second off my BL FOX time to be within the benchmark.
I really liked racing in the FOX, it's a very controllable car that allows for more aggression in racing. I was never worried about crashing into the other guy because I had full control of the car at all times and could turn, slow down or accelerate anytime I wanted. I could focus on battling for position, rather than having to focus on taking the turns without losing control.
