Go to the sphere marked on the screenshot, and a drag race will begin. Select your opponent and race with him. Infernus and Bullet opponents are impossible without the same car. You can even use bikes for this race. Good luck and Have fun with this mod.

Install:
Just put all the .cs file to your GTA SA/Cleo folder, and the .fxt file put to GTA SA/Cleo/CLEO_TEXT folder.

P.S: Play fair, dont block your opponents way or do something stupid.
