I've known Si and Paul down at SD for years now. They started out building show cars, and produced some awesome Mk1s and Mk2s etc. These days they sell parts on eBay and undertake major mods (engine transplants etc.)
They have fitted all my bits so far, and are steering me towards a Jetex 'xhaust
Never faulted their work on all my cars.
