Idk if you want these but i got some blown ksport coilovers off my is350, came with the car but i replaced them for bags so they're sitting in my garage dusting away. $100 plus shipping, has no keys unfortunately
I have UAS bags on blown Megan LP's with modified lower brackets and UAS upper rackets for the rear. Rebuilding them shouldn't be too much of that's what you're looking for. PM me if you're interested.
