Time attack Trial mountain and Deep forest. Try to learn the Nurburgring north. Mess around with new cars stock on time attack at aforementioned tracks.
I run a Super GT Championship on an italian message board and occasionally race in the gtplanet one, best fun I've had with a racing game since Daytona USA 8 cabinets LAN battles at the arcades.
I usually take different cars around the ring mostly now, I do the a-spec events sometimes but the endurance events are left and dont really feel em atm, but ya arcade mostly.
Online, I've found some good rooms recently. I some how always get bumped/spin out early in the race and spend the rest catching back up. On 3 lap races cant do much though
My B-Spec is maxed out, so all there is left to do is get trophies and A-Spec to 40. I'm expecting to be lvl 37 A-Spec tomorrow, only recently being told, exp wise, I'm only HALF WAY THERE.
