Leaf spring question for the road race guys...

I realized that I have these dropped front spring hangers left over from my street linx kit. So if I do use these to lower the car, from my understanding it still will not change the high camber of the ss springs, correct? And it would also possibly mess with pinion angle?

What "camber" are you talking about? The leaf springs wont change camber.
The arch is what you should be concerned about...
Leaf springs not only support weight. but they also control axle location. So if the spring is arched at ride height a bump will change the axle location differently than a rebound which feels odd to the driver and can upset the car's grip. And you can use angle shims to fix pinion angle.
