Muscular Style and Today’s Technology in One Wheel
Weld Racing, the racing wheel company with the most wins on its product year after year, introduced the 2010 RT-S line of forged aluminum wheels at the 2009 PRI Show in Orlando Florida. The nation’s largest performance and racing show was the perfect place to unveil the new line’s two designs. The S71, a traditional “Weldstar” design, and the S74, a sophisticated Y-spoke design, make up the initial RT-S style offering. The available sizes range from 15”x4” to 18”x18”, to fit the wide array of tires available today and vehicles from classic to 2010 Muscle. The 15 inch diameter versions are available in February, followed by 17 inch, then 18 inch diameters during the first quarter of 2010. 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 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 only 60% as strong as 5000 or 6000 series 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 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 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.
Weld RT-S wheels are available in widths to 18” to accommodate monster tires. Each design is modeled in 3D, and then tested with F.E.A. and destructive testing in our facility to insure your safety. 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.
For over 40 years 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.
