These are Megan Racing Track coilovers, which come with 12/10 spring rates. I know that may seem super stiff, but they ride better than my Tein Super Drifts which were 10/8, so the damping is pretty good. They're 32-way adjustable as well.
I don't know how many miles are on them, but none of them are blown or leaking. The front drivers side (left) lower mount is frozen, so you'll have to get that unstuck to adjust the ride height. They're set decently low.
$600 shipped. I would prefer pickup and cash payment. No paypal.
