511 or 502?

The best way to understand this is to pick the car up from underneath and hold it in your hand. If you pull the throttle hard, you will feel the car and pivot in your hand wanting to pull the front up. If you grab the brake, teh front will go down. With a shaft drive, the car will pivot to one side when you pull the throttle hard...

Think thats about right - hope it helps...
