Bump stops?

The amount of front end rise has alot to do with front to rear weight ratio. A 50-50 car doesn't need front or rear suspension at all! Don't think so? Look at Top Fuel or Funny cars? The heavier the front is to rear the more weight transfer your going to need. How much is all in you doing the R & D on your particular set up. In the case of my BB scamp, it launched the best when I limited the front rise to about 2".
