Forza Street

Each episode consists of 6 events with multiple races per event. As you progress in each event, your opponent's difficulty will increase so be sure to tune and upgrade your cars to increase your cars rank as well. If you find yourself struggling with races, go back to earlier races to grind out tuning kits and upgrade parts to max you cars level.

For this achievement, you have to complete all 6 events for Episode 1 to unlock this.
