use the " nissan fairlady z lm concept "( won in the all japan gt championship from memory), thats all i used and it did it ezy, overlapped the car coming second 6 times, by 3x speed u mean "medium pace" yeah??? i left mine on 4 ( increased pace ), and my b speccer driver killed them all
and once u win the nurburing 24 hour u'll get the f1 car, use that to own the bitch ass super cars in the gt world championship, i at first used my toyota gt one car ( 1011hp to a 700kg car.... oh yeah ), it won it origonally but jst, now i have the F1 i cheat and use that, it kills them all lol
