Been spending most of my GT time at Sierra. I really enjoy this track, and if it's a hint to the course creator, then I'm really looking forward to it.
Arcade race...
Tough to get a tight race, but it's doable.
I souped up this California a while back, and decided to take it for a lap. Pretty much a race spec, 714hp, RH tires, maybe maxed out, not sure. Still drives surprisingly well, but it'll bite you in a heartbeat.
