I have purchased products from art on two occasion and they have always eventually pulled through with suppling the correct parts. However I haven’t had the most amazing experience for two reason: 1st purchased was a turbo smart 45mm hypergate v4. This purchase arrived very quickly which was great, but somebody had already been in the box and removed on of the flanges required to be welding to my turbo manifold. AET never rectified this issue after making multiple phone calls to highlight the issue causing me to spend more money with another company. The second purchase consisted of a new spring for my wastegate, once again it arrived very quickly, but the incorrect spring was supplied. On this occasion the did send me out the correct spring within a couple of days. So with my last purchase they did managed to supply me the correct part that’s I had purchased in the first place.
