Ford Racing#397-M-1007-S177AFocus SVT Wheel
Ford Racing uses the Society of Automotive Engineers (SAE) and American Society for Testing and Materials (ASTM) standards: SAE J175 and J328 for impact and fatigue testing and ASTM B368 for chrome testing. These standards define a series of tests that ensure a wheel's safety and finish. You usually get what you pay for, don't get wrapped up in a cheap price.
Ford Racing offers wheels that are built to the highest of manufacturing and engineering standards for safety and good looks. Ford Racing gives you a great mix of quality with a resonable cost. There may be cheaper wheels on the market, but you would have a hard time finding safer wheels.
This test simulates a curb impact on the side of a tire/wheel assembly. During testing, a tire/wheel assembly is mounted at a 13 degree angle to a test fixture by the hub. A weight is dropped from
9 inches onto the assembly at the tire/wheel intersection. The mass of the weight is determined by a formula using vehicle weight. DYNAMIC CORNERING FATIGUE TESTING
This test simulates lateral loads applied to a wheel by the vehicle. During testing, a wheel is clamped to a fixture by the front face and a constant bending moment is applied through the hub. A newly-designed wheel runs a minimum of 1,000,000 cycles before approved. The load applied is determined by a formula using vehicle weight. DYNAMIC RADIAL FATIGUE TESTING
This test simulates axial loads applied to a wheel by the vehicle. During testing, a tire/wheel assembly is mounted to an axle by the hub. A large drum drives the assembly while a load is applied perpendicular to the tire patch. A newly-designed wheel runs a minimum of 5,000,000 cycles. The load applied is determined by a formula using vehicle weight. CHROME QUALITY TESTING
Copper-accelerated acetic acid-salt spray, commonly known as CASS testing, is the standard method used to test the corrosive performance of copper/nickel/chromium-plated wheels. The test is performed in a sealed chamber with a highly acetic spray directed onto the wheel for a predetermined amount of time, usually 66 hours.
