Like the topic asks, if i go and have my sfc's installed this week, how hard will it be to later install lowering springs and struts? I think i read somewhere that you are to weld the lca to the sfc. Maybe i totally misunderstood it, but i need to make my ride a little more comfortable, and i allready have my sfc's in my room. Every little bump my dash rattles and whatnot, my stupid struts are shot and im sure the shocks are too. But yeah, if i were to install the sfc's, what do they make harder to work on in the future (exhaust routing, springs, struts)?

They won't affect changing any of the suspension components at all. They're pretty much out of the way of everything, except for the exhaust on the passenger side.
