yea sell those pieces of s***, im sorry you got ripped off... lesson learned.
ground controls are good. but putting any springs on stock shocks is never the greatest idea in the first place. if you dont have the money i would save up and get you a nice combo. do the math to where maybe having coilovers is not necassary i.e. changing height does not need to happen.
i have espelir springs and tockico shocks, got the great drop on the car (about 2 fingers between tire and fender) and no need to adjust it at all.
sell those on ebay though stat
