for those of you w/supercharged cars with either stock suspension or 'stock' modifed as in a gt500 (05-09 mustangs), I cannot say enough good things about this coil over set up - originally it was $2,500, you can find it now on ebay or elsewhere for $700-1,000 - it is very stiff, but adjustable for height and ride - lean almost completely goes away - Stage 3 (
www.stage3motorsports.com) might have some more, but I think I may have gotten the last one, but try ebay if you are interested or call stage 3 and ask for John
