Ha ha, hey new guy! I was like you long ago. I remember the first time I took a race-modded car in the Apricot Hill enduro and got 3 or 4 laps ahead of everyone! Yeah, the thrill of speed is fun for awhile, but like the others say, your victory will be hollow if you keep at GT2. I'm gonna echo everyone else: race-modded cars against non-race modded cars is a no-no. In the real world, they'd surely separate the world of Gran Turismo into a complex system of classes to make sure weight and power, not to mention tires, suspension, brakes, etc. are all kept in different categories so no car has too much of an advantage. You'll see what we mean...
