Wow! Just looked at the entry list. So many changes. No more Skylines at all! I guess they used the last 1.5 seasons just to tune in the engine. But now, they have to dial-in a whole new chassis setup. Nissan might have a problem w/ the already dialed-in Supras and NSXs in 04.
MR-Ss replaced w/ Celicas (more now), Mugen's running an NSX in GT300, Silvias replaced by Fairlady's, no more M3s, more 360GTs...damn, lots of changes! I'm sad to see the M3s go. They were doing better on their sophomore season, but the weight enforced on them were really killing them. I wonder what advantages the Celicas are offering over the MR-Ss?
edit: reading the site Twincam posted...very good stuff! Now I see what changed for the NSXs for 03+. I remember something about the underside panelling for the NSX being limited to a certain x-meters beyond the front, so that affected them aerodynamically since they can't use a completely flat underside. But, they gained advantages in mounting the engine longitudinally by gaining room beneath the engine (no longer have to run exhaust piping below the engine) to mount the engine lower, weight is more evenly distributed side-to-side w/ the headers, and the tranny can be mounted longitudinally also to better center the weight.
edit: wow, 04 season w/ turbo'd NSXs and Supras going down to 4.5Ls...so many changes!
