Revlis, Revlis, Revlis....as the driver of the fastest color, I am surprised at your comment. Yes whats in front of you is usually more important. But on a busa, it is so much fun to see Z-10s, Z-12s, Vipers, Corvettes, Ferraris etc etc in your review mirror. With those extensions you get an even greater panoramic view of the busas "leave em in the dust" power. Moreover, you'll have more "rear view peripheral vision" with which to see the law enforcement folks trying to catch up with you....not to mention the greater potential to spot some dope crazed teenager about to rear end you.
