I ran it in different cars the whole time for challenges I used the Lancia Straton Fully Tuned( to easy oops) the first time, then a fully tuned besides limiting it to 387 hp RX7 A-Spec on Normal tires the second time, 3rd i used the 1966 Shelby cobra fully tuned besides only using 423 hp on sports tires, lastly I got sick of long challenging races on that same race so I used the Lotus Elise GT1. Also for more info one all of them but the last one the tough competitor Atlantique 400GT entered.
