I turned a few laps at Suzuka yesterday afternoon, my time severely curtailed by an update download and installation. And having to agree to the Terms of Service at least twice... maybe three times. (FU, Sony, I said "I Accept" already!)
The F2007 at 500hp is very manageable. I ran it on R1's. Still have to run an ATX though. I just can't seem to flick through the gears fast enough but the auto tranny handles it very nicely. I could see racing these things.
