Japanese National Champion Takaaki Shimo is running a standard Mugen MRX-5, the same car he won the Nationals/Worlds warmup race here in Kei Tune with some months ago. With the track not being sugar watered for this event, like it was previously, his setup has needed to be adjusted. Firstly the car was too loose on track and with some adjustments he stopped the rear from stepping out but then it had too much grip and not enough steering. The multiple Worlds podium finisher has reduced both the front and rear toe and this has given him the steering he wanted. To power his car Shimo is running the all new O.S. Speed 2101 R, which was only released 2 weeks ago.
