Lol, I'm pretty picky when it comes to racing.
I don't use FF cars, I don't race anything below 600pp and even in the odd chance I do race something that slow, it would never be on a track as open as GVS. I could handle Eifel, Tsukuba or another tiny track, that at least makes it appear like I'm going fast. I don't enjoy the game, if there's no concept of speed, that's just me.
As for the CT230R... I didn't take it to GVS, but I would ASSume, it would be right around the 1:47 mark. Seeing as how it seems to be comparable to my Enzo, but the Enzo would blow it away on straights, of which GVS has it's share.
I can run some laps at GVS later, I have been working on a 97 Civic, but it was just for the Seasonals, I didn't have any plans to use it beyond that. But it's at least RM'd. I think it's one of the only FF I own.
