It's all about top speed. My car is a street and track car. I want it to be fun to drive on teh street. But I also want a higher top speed on the front stretch. If I want to raise the top speed in 4th gear, I have two choices. 1. raise the rear gear ratio to something like 3.00. But then I lose that off the line torque that's so much fun. or 2. Increase the rpm potential of the engine. Then I get both.
