If I'm not mistaken, pit stops at the 24 Hour Le Mans event come after maybe 8 or 10 laps. That equates to about... 24 to 28 minutes at least.
I normally think of Suzuka as a high-speed track, but it's also very technical. Just look at the Esses in the early going. Then you head under this little tunnel out to the western end of the circuit, complete with tough turns all the way to Spoon corner. Then you haul you-know-what down that straight to 130R (am I right?). And then there's my least favorite part of the track, the Casio Triangle, complete with first gear corners and maybe even missing pit road if you have to enter the pits. Suzuka will of course be the penultimate land of the 2004 Formula One World Championship. And for GT4 to include Suzuka will be pretty cool. Suzuka to Japan is like Indianapolis to America in my view. If I were PD, I'd try to utilize Suzuka as much as they can for some of the bigtime races. If you want to be simple, I'd include the eastern end of Suzuka. After all, for those who played "Le Mans 24 Hours," you may know what I'm talking about in terms of Suzuka East. But if you don't, Suzuka East does not utilize the overpass. The track layout looks more like an oval, with the exception of the Esses and two tough curves and one mid-speed corner. My best lap time with this? I think I pulled a 0:40.019 once (those Time Trials are damned tough, requiring a 40-second lap time for the Prototypes). And if you want to get technical with parts of Suzuka, the western end includes the overpass and is surely more technical than Suzuka East.
But as I said, Suzuka should be utilized pretty well if you ask me. Don't be surprised if you have to race a 50 or 60 lap endurance race there, folks. Of course, that's what I think. We may race this track as much as Grand Valley in the past three GTs.
