I have a set of stock IS300 springs with about 150k kms on them. Nothing wrong with them, in perfectly fine condition. $30
See pic: (Black ones are the stock springs, brass ones are lowering springs which are not available)
Also have one tail light, rear right hand side. The outer lens has been tinted making it hard to match however and there are a couple of minor scratches on the lens, so it is being offered as-is for parts, $10.
