FAQs
Q: Which games does this support?
A: Any Forza Motorsport title or Forza Horizon 2 and later. Vehicles will typically need race suspension, anti-roll bars, brakes and differentials. In some cases, cars are stock adjustable and you should *not* install a rally suspension. You will also get better results without stability management (STM) and other assists. Fine-tuning in FH5 is best done with simulation steering.
Q: How does it work?
A: Enter weight, weight distribution, performance index, and drive type. Hit "Next" to see your results. Copy those results to the tuning menu in Forza. Follow the "next steps" section below the results to make your tune even better.
