I'm not trying to be a price cop, but if these are the DSE standard coil springs (not coilovers), you are asking significantly more than you can buy them brand new from DSE, at least per their website.
I have to agree with above on GNS performance website (a supporting vendor BTW) they are $195 for 2" drop front and $210 for 2" drop rears.
Are yours different rate or something?
woops I remembered paying 500 bucks for them shipped. GNS is +70 bucks shipping and handling which brings them to 475 from GNS. I will take 450 shipped.
