Good evening all, having decided to go for a set of HSD coilovers, I was tempted by some used Tein CS alloy bodied ones from ebay.
The fronts are in great condition and they all have good damping and no leaks.
I am now in a dispute with the seller due to the condition of the rears being riddled with galvanic alloy corrosion.
I have removed the powdered aluminium oxide to see what is left. Not being a metal expert, I am not sure if the corrosion will have rendered these units unuseable, or if they are thick enough to cope with losing around 0.5mm of their thickness in places.
Pictures attached for those who are intersested and coments welcome from those with an unhealthy interest in metallurgy. Of course you are also entitled to mock me for trusting an ebay seller;
