The struts likely need to be replaced yesterday. Without knowing what struts they're going on, we can't really advise you. Putting springs on original '02 struts would be a waste of money; if you're going to tear apart the assembly, you want to replace everything.
Megan Racing anything is garbage. You saw them on eBay for a reason.
Skunk2 is garbage.
Tanabe makes an alright spring, but I wouldn't bother with them.
Moral of the story: give us a budget, then ask about springs. Until then, keep the stock ones.
