The build plan
The Flossmann GT Street kit brings a front splitter with flics, a DTM style hood, vented fenders, lightweight doors and a 120 cm rear wing. It is race car aero on a street chassis.
APR carbon side rockers and CSR rear fender blades connect everything, so the car looks lower and wider from every angle. OLED sequential tail lights in red smoke finish the rear.
The RacingDiffs EvoHybrid Basic clutch pack makes the rear axle predictable when you get on the throttle. This build is about presence first, but it backs it up.
