Leaf spring question for the road race guys...

Raising the front spring eye has an affect on a couple of things.
It will take out most of the built in steering that is designed in from factory, which is a good thing.

Very true... The factory designed the suspension to have roll understeer. Good for keeping grandmas on the road in the wet, bad for performance.
When you level out the spring it makes it more neutrally balanced. I am just using my stock ones, with lowering hangers and adjustable shackles.
