So wheels are finally back on the the car and the test drive was knock, bang and leak free so these struts seem to be in good health.
The colour didn't come out quite as expected but I do like them. In the shade they are a silver / grey but when in the sun they really pop with the metallic flake in the powdercoat.
I need to get a better colour match for the centre caps, but in the sun they are a near perfect match so not super high on my priority list.
