WTB: Coilover springs

[OrangeFiero]

Ok so i installed my coiovers and i love them but the rear needs to be stiffer and lower. Currently i have (groundcontrol P/N GC150.64.92) 2.5" diameter 6" long springs at 525lbs. Now i would like something along the lines of 4" or 5" long and preferably 600lbs +

Im not looking to spend a lot, so im up for trades or used springs, give me a price shipped to 80907 if your selling please.
