I used the second car I bought, a r34 gtr vspecII. After winning everything is a breeze with the 787B. The skyline I believe had all the upgrades , stock transmission, and I didn't change any settings. The most trouble was with the GT One Race Car. It was a VERY close race, used a lot of drafting. I used hard tires so I only had to pit in once, while I think the GT One pitted in a second time and that's what saved me.
