What shocks do you have in it now? You'll also probably get a lot of recommendations to switch over to Caltrac springs with the bar but even with SS springs you should be able to tame it down. How big is the budget? You can get Calvert adjustable springs for $100 each, double adjustable shocks cost a lot more.

I started making my own lower shock plates so I could get the shock in the correct position. Getting the correct travel on the shock was important for my application.
