its been so long but i think about 2" a lot depends on how fatigued your springs already are. you can make lowering springs from square tubing, the same used for boxed steel frames. there usually a minium charge which is high but if you explain what you are doing they may waive it, go in off peak. this sq. tubing comes different dimensions. 1x2. 2x2, 2x3 and so on, just decide how low you want to go. longer u bolts will be needed. ron
