Simmons Wheel custom program allows to maximize wheel fitment without the limitations associated with one-piece wheels. Simmons Wheel's fitment specialists work to find the best balance between required brake clearance and maximum outer lip depth for the most aggressive appearance Simmons Wheel components - wheel center, inner rim section and outer rim section - are produced in the same facility, with the same machinery, and using the same technology as F1 race wheels. These components make up the foundation of a quality, custom 3-piece wheel program. Rim diameters are available in 17", 18", 19", 20", and 22". Simmons Wheel's complete, in-house inventory of all 3-piece wheel components means quick turn-around with assembled wheels shipping within 2-3 weeks of order receipt. Precise wheel assembly is performed at Simmons Wheel using an exacting process that maintains and enhances the structural integrity originally built into each individual wheel component. Simmons Wheel supplies a proprietary fastener specific to its 3-piece wheels to ensure the highest level of structural integrity. These fasteners alone do not guarantee a properly assembled wheel and tightening these fasteners by hand, or using ordinary power tools, does not result in repeatable torque accuracy. Thus, Simmons Wheel uses a factory-certified Ingersoll Rand DC Electric Fastening System to tighten proprietary fasteners. The assembly torque of these critical titanium fasteners is controlled and repeatable to less than 1/2%. Simmons Wheel's fastening system produces traceable measurements of torque to spec every time. In fact, wheels custom-assembled at Simmons Wheel are shipped with a computerized print out that shows in detail the settings used to assemble each wheel. Proper torque (fasteners tightened to spec so they won't break or loosen) and run-out (radial and lateral roundness for vibration-free rides) are recorded.
