First, do up to the A licence in tests. You should get two cars. Sell both of the cars, buy a Toyota Celica 2000GT-Four from the Historic Showroom, and outfit the car with a small turbo kit, a chip, and anything else you think is nescissary. Go to the special condition events and race the Tsukuba Circuit on easy, you should get the MAZDA RX-8 Concept (Type-I). Take this new car and go to the RX-8 cup in the Mazda dealership. After doing that you'll win the MAZDA RX-8 Concept LM Race Car, in which case you can win almost any race available.
