I do know, unless you build new spindle arms like we saw that one company do, normally you don't go very low because of the binding issues. Somewhere in the 1/2" area maybe. Every car is probably different though. For example RCE refused to make a "lowering spring." They wanted a performance spring. So 10mm and 15mm drop were your only choice. Any lower and you'd hurt performance vs help it.
