Driving this car as standard on a track is a handful. Made some adjustments so that the car can drive better.
Gearbox from 1st to 4th is just like a standard 4-speed on a Challenger, with a 3:54:1 Final Gear. Added fifth gear helps to max out a higher top speed, so as to not limit the car to simply 1/4 mile drags.
LSD is setup to manage the wheelspin more equally. With these settings you can slide the backend around with control, but not so much as to hinder maneuverability.
Lastly changed brake settings to something more suited for use without ABS. May need changing if using a steering wheel setup.
