"I personally prefer one-make tire system.
If you compete under the same conditions, you will see your true ability, and if you win, you will be happy, if you lose, you will be disappointed.
However, at present, everyone will only make excuses.
I would like to introduce a bidding system in SGT and to shuffle tire manufacturers every 3 years.
Well, some teams (BS user?
) don't like it, but I think it's more fun and rewarding to have proper competition."
