Interesting test for Super Formula and Yokohama.
Super Formula engine manufacturer testing held at Fuji 5/12-13. Toyota and Honda were bringing to each one test car.
Kondo Racing prepare Toyota #05 car driven by James Rossiter. Drago Corse prepare Honda #00 car driven by Takashi Kogure. But this test was not only engine testing. Rossiter and Kogure tests 2 tyre manufacturer.
First is regular Bridgestone. The other is Yokohama tyre. But Yokohama says it is research and development testing.
However, In Japan some media rumors Yokohama replace from Bridgestone near future. So interesting testing for next year.
Yokohama tyre supply many category (WTCC, Super GT, F3 and Macau GP, Rally, Global Rallycross, Super-Taikyu etc).
But Yokohama not supplied big-formula category. If Yokohama supply for Super Formula since Formula Nippon 1996.
