3SDM monoblock cast wheels are available in a number of sizes from 16 to 22 depending on design. They are made from prime alloy ingot A356.2 aluminium. Tested to destruction at our R&D facilities, all 3SDM wheels pass rigourous Impact Test, Radial Fatigue, and Corner Fatigue before they go in to production. 3SDM polished face wheels aren’t the normal diamond cut that you see everywhere, ours are "superfinished" on special turning centres so the radial lines are almost invisible before going through a seven stage aerospace pretreatment. Our cast wheels have a powder clear coat on all gloss finishes.
Bridging the gap between our cast range and our bespoke forged range is 3SDM flow formed "Spin Forged" range. Flow forming is a process where a wheel is cast and then the rear rim barrel is extruded enabling a wide range of width’s and offset’s from a select number of moulds. Not only does this method offer a range of applications not economically viable via traditional casting methods, the resulting wheel’s produced are incredibly strong yet comparably light in weight. In conjunction with 3SDM extensive brake caliper database and 3SDM experience gained with in house produced forged wheel program 3SDM able to deliver a vast range of vehicle specific applications covering many of today’s sports saloon’s and super-cars.
Every 3SDM forged wheel is UK made from concept to realization, in our own 100% owned manufacturing facility. This allows 3SDM highly trained engineers to have complete control over all aspects of the manufacturing process and gives us extremely quick reaction times to market demands. For every new application and specification a new set of drawings are prepared, there is no generic brake clearances, no generic offsets. 3SDM make forged wheels for your specific vehicle, and to your requirements whether that’s to maximize concave, dish, or both. 3SDM have most OEM brake caliper profiles on file as well so there’s normally no need for you to give us any complicated brake measurements.
