Kansas City, U.S.A. April 11, 2011—
Weld Racing, the racing wheel company with the most racing wins on its product every season, released the 20” S71 RT-S wheel for sale in March. The S71, a traditional “Weld-Star” design makes up the initial 20” RT-S style offering. The wheel sizes range from 20”x5” to 20”x17.5”. The forged billet centers have three choices of brake caliper clearance so you can use anything from drum brakes to billet 6 piston calipers. Vehicle applications cover classic 1930’s Hot Rods to 2010 Muscle. Forged from primary aluminum alloys in the U.S.A., as are all Weld Racing wheels, they are lighter, stronger, and truer than other brands. The quality alloys in the wheels polish to a brilliant shine and resist oxidation better than other alloys. The option of eye catching black anodized centers with milled highlights adds to the choices and appeal.
Forged wheels have numerous advantages over cast wheels and non-forged billet wheels. A cast wheel is made from A-356 Aluminum that is melted and poured into a mold. This material is at best 60% as strong as 5000 or 6000 series aluminum alloys that are forged into shape. In addition the cast A-356 is brittle and porous. Not exactly properties you want in a wheel, especially in a high performance application! A billet of aluminum alloy that is not forged to approximate shape before machining does not have grain running from center to rim like spokes on a wheel. A forged billet, done correctly, does. This prevents de-lamination failures that can occur during high loads in a pure billet wheel. The forging process also increases the surface density of the wheel improving durability further. With a stronger material you can use less of it to build the wheel reducing its weight as much as 40% and still have a more durable wheel.
The RT-S wheels are three-piece forgings, for application flexibility, that are assembled by welding. In addition to the large array of widths and offsets, there are three mounting pad heights available to fit your mild to wild brake package while maximizing the depth of the outer wheel lip. Primary forging grade aluminum alloys are used to create these and all Weld Racing wheels and this means no recycled scrap is used, as in most cast wheels and others. The difference in quality is obvious from the appearance, the strength, and the durability.
Each 20” S71 RT-S wheel is modeled in 3D, and then tested with F.E.A. and destructive testing in our own facility to insure your safety and the wheel’s performance. Capable of handling 1200 horse power, 1.2 second 60 ft. times, 1,580 pound loads, and very high speeds, these wheels are the answer to today’s powerful and sophisticated Hot Rods and Street Machines.
Since 1967 Weld Racing built technologically superior wheels in the U.S.A. Today Weld Racing L.L.C. continues the tradition of building Racing and High Performance wheels in the heart of the U.S., using 21st century technology while giving the customer top quality, true craftsmanship, and excellent customer service.
