I am buying a set of Pre Gens today and i'm putting a 225/55 on so i'm wanting to lower my GP. I was on Ebay today and seen a set of lowering springs, this is the actual auction I was looking at 97-03 PONTIAC GRAND PRIX GTP GT W-BODY SPRINGS LOWERING - eBay (item 170583262415 end time Jan-01-11 15:02:42 PST).
This may sound stupid but i'm not sure what the differance is between these springs and a set of eibachs. If I need to spend the money on eibachs then I will but these are about half the price. So I guess I just need some feedback on what to go with. Thanks!
