I forgot, just remember: no matter how much you dub 'em out muscle cars just aren't as fast as tuners and luxery sedans and the others but when racing other cars the system makes them about as fast as you (depending on what car you are using) example: if you race tuners with an exotic the computer will make the tuners race faster so that you don't have a super advantage but if you race an exotic with a muscle car it will slow it down to give you a chance.
Never use NOS at the beginning of a race
Which is worse? Being hole-punched to death or being eaten alive by the cast of "Friends"?
