Front end setup (Drag Racing)

What possible benefit would having the nose raise possibly give you? Every ft-lb of torque wasted in lifting the front of the car (from the rear) is a ft-lb not being used to move the car forward. I would concentrate on traction and let the nose do what it wants. Sure it's gonna come up a little, but I wouldn't spend any money trying to see how high I could make it go. A better approach would be to move as much weight away from the front of the car as possible.

There is no benefit until you have maximized your traction for a static body. But once you have maximized the bite with the instant center forward and low, you aim to raise it and move it towards the rear so more weight is felt by the rear tires. Then you maximize it again with the extra weight that is transferred to the rear tires. With a 4 link setup, you can set the instant center so the car doesnt waste power transferring weight. Which is why race suspension cars when set right move straight forward, not up and then forward. For everyone else, weight transfer is crutial. I dont want it to move much, but it should be free to move easy, and it should be easy for it to raise via thin torsion bars that are preloaded a lot.
