Ok, I went in for a couple of races on the Japanese Championship (Expert Series) yesterday with my bone stock Subby WRX STi '07 since the field consisted of comparable AI cars like the Supra RZ, NSX etc. However, I found that I was coming in about 4th or 5th. I decided to upgrade my tyres to Sports Soft as that usually evens out the playing field a bit more. I don't suppose the AI cars are highly tuned or anything are they?
