Rear Chassis OpenRC F1 2017 optimized for F104 Tires

Turns out the original Rear Chassis OpenRC F1 (2017) is a tiny bit to close to the tire when using Tamiya F104 tires. When you race the car the tires hit the chassis which does harm to the tire and the chassis as well, so I optimized the chassis giving the tires a tiny bit more space.
