What springs you running with the belltech spindles? That stance is where I need my Cutlass.
They are the moog 5658 springs up front. These springs are somewhere around 500 lb spring rate. Moog has a spring which is the same height as these but are over 700 lb spring rate. With the LS1 in my car it needs the higher spring rate. I am not sure what the moog spring part number is without looking it up. I would suggest the 700+ spring rate.
