The RB4 only LOOKS like the 80's Celica GT4. It's suspension is way superior to that car. The RB4 has a great Mcpherson strut all-round suspension, whereas the 80's GT4 had decent struts up front but absolutely horrid rear trailing links that walked laterally in response to lateral forces.
At least the XR GTT is a very close copy of the Mitsubishi Starion, both appearance and suspension wise. Just hope it gets a powerband close to the RL 80's car. And I agree the that road cars should be given finite gear ratio choices, though 2-way adjustable dampers are perfectly resonable for anyone planning to drive road based cars on the track.
To be rasonable, the FXO is definitely non-standard as it's tires are HUGE and so are its massive fenders. Yes, that the OEM tire package is absolute crap, typical of toyota. Well, my friend's 191hp corolla has horrid 195/55/16s all seasons as OEM, and they struggle to contain 191 horses. Doesn't mean that such a car should be FORCED to wear those horrid boots to a track event. In fact, its optimal size is 215/45/17, something well known to those who tune it.
To level the playing field, let's just increase the RB4s tires as much as what you would realistically do for such a car. Notice that the 90's GT4 had less power but MUCH MORE top speed then the lighter RB4! As I've said, there's something very wrong with the Rb4's aero ATM. 215 to 225 shouldn't be a problem. It's not as if I'm trying to stuff FXO sized meatloafs to the RB4.
