There is a post in the drag racing section that might help out a bit:

Do you think you could get away with taking some heavy leafs(like 2 tons) cutting the rear section off so they are just in the front? Ideal would probably be the main leaf of the same length, cut the eyes off so its just as long as the main.
Controlling the axle wrap is step one, then keeping it planted is step 2.
