Choose your Porsche.

The factory roof on a Spyder is a fine thing once it is up, and a nuisance every time you leave the car for a short while. Its owner, an engineer, made a cover instead: ripstop outside, satin inside, on in half a minute, and light enough to live in the glovebox. Other Spyder owners wanted one. Then they wanted covers for the slots the roof leaves open, and the caps, hooks and brackets that followed.

Everything is designed and made in Cynghordy, in mid Wales. Parts are printed in a high-temperature polymer and made when you order them, in the colour you chose. Decals are cut in-house from automotive-grade vinyl. The Spyder Cap is cut, sewn and assembled by hand. What we make is run on our own cars first, on the road, on track and at Autobahn speed.

A few doors along, WDT Werks blends the detailing chemistry that keeps it all looking new.
