Super Stocks Springs have i reached the limit?

No, I don’t think so. Reaching the limit would manifest in spring wrap or collapsing the spring on the hit. My guess is with the 2 step, you are topping out the front suspension too abruptly and upsetting the tire. Slow the nose down just a hair. Does it chatter the tire? In all actuality there are better bolt on setups out there. Move away from using the spring to control the tire to using the shocks.
