I've read both sides about springs on stock shocks & struts ..some say they have no issues then some say eventually they will fail with lowering springs. I know most people run koni yellow with lowering springs. I'm not so much looking to be cheap you get what you pay for. If it worth more to wait and just get coilovers I don't mind doing that. Overall this will be a daily driver (work , school , weekend driving) or spirited driving. Overall I want to go for a flushed look.If you don't like swapping suspension components, then do yourself a favor and save up for a matched set of springs/dampers or a coilover kit. Marcus (Heeltoe) has some nice offerings.
If you cheap out now, the mismatch between the dampers and springs will just be more pronounced when you have less sidewall and you move the heaviest part of the wheel farther from the wheel center.
