It's very easy to win the Suzuka seasonal with this car and this tune, just do a two-stopper in laps 2 and 8 (RS-IM-RS) or in laps 2 and 7 (RS-IM-IM or RS-IM-RS depending on the weather). Guaranteed win.
A few days ago made some tunes for the '00 and '01 Supras that work very well on the au Cerumo Supra (at least for me). I posted the tune in the Suzuka seasonal thread here: New Year Holiday Challenge: Suzuka Circuit 2014 10 Lap Survival Race
@ Praiano: Any chance of doing a set-up for the Pennzoil Nismo Skyline GTR '99 and the Calsonic Skyline '93 that can beat the Suzuka seasonal? Can't find a way to get rid of understeer for the Pennzoil GTR, the tune that works for the Calsonic Skyline '00 doesn't work for that one for some reason.
The Calsonic one is just too slow, but that might just be the car's nature that it can't really keep up with the other SuperGT cars.
