Hello, i've seen some tunings before, but they were about the normal version and not about the v-spec, after some tuning, my car just "broke"... he don't turn like before, he was a turbo stage 2, with almost everything setup on racing or the best (not customizable), so after run and win 150.000 cash, i decided to upgrade him, and i can't drive my favorite car anymore. Pls someone help me 🙁
