Place 'PremiumDeluxeRevamped.dll', 'PremiumDeluxeRevamped.pdb', and the folder 'PremiumDeluxeMotorsport' into your GTA V/scripts/ folder. 

IMPORTANT:
This project is based on the original Premium Deluxe Motorsport mod created by ImNotMentaL.
My version updates, rewrites, and fixes parts of the original mod, but full credit for the original concept and foundation goes to ImNotMentaL.
