Hi! As above. Having difficulties with unseizing mine. Tried the spanner, with leverage, WD40 for 3 days, nothing. Read threads about derusting them with coke. For example: Ways to revive rusty coilovers? - Scionlife.com So... Until it doesn't meet rubber parts, is it safe? It's a s14 cusco coilover. Threads are perfectly clean, no rust at all. Other parts are in a good condition aswell. (no rustbucket ) But I guess nobody adjusted it after installing and haven't used any lubricant to prevent corrosion. So coke? I have now a few liters at home. Opinion? Anybody tried? Cheers!
