Now available in both 1966 Yenko Stinger form and 2001 Giant Head On A Corvair form. With distinct physics for each.
To avoid confusion the original mod's folder is the Giant Head, you could delete it anyway if you want to be certain. The new car is oneweek_yenko_stinger.
1966 tires are not sticky. Maybe build up to driving fast cause cornering speeds are not high.
