I have a set of Fortune Auto 510 series generation 6 coilovers for sale with 4k front and 6k rear springs. They handle like a dream, but are too stiff for me even on full soft on these potholed Boston roads. According to the previous owner they have about 7k miles on them. They're in pretty good condition overall except for the rears, which have sway bar endlink ends still attached and a slight scrape from where I tried to cut the end links off. Comes with all adjustment hardware. They are $2395 new (Toyota MR2 (ZZW30) 2000-2007 - 510 Series Coilovers), but I'm willing to sell them for $1500 shipped in the continental US. If you're near Boston (within 1 hour) I'm willing to make an in-person transaction and take $60 off of the total price. Happy to answer any questions and take more pictures upon request.
