Called for a part that was not in the assortment, but was available from one of their partners. Product could be ordered without difficulty and was delivered quickly. Very nice communication, thank you!

Had the parts that I could really only find elsewhere on the internet via an awkward import promotion from either the UK or the US. Tuningsupply had them on the website, at a good price and they were also delivered quickly. So good service!

So cheap!!! At first it was really a gamble for me to order my rims from Tuningsupply because they were so very much cheaper than elsewhere. And sure enough, on the ninth day DPD arrived at the door with my rims. Really a total of 360 euros cheaper!!!! For me a very big applause for this company.
