After the wheels have been cast, the wheels must then be heat-treated to T-6 standards, which is required to ensure strength in all wheels. This is done off-site, and daily shipments are constantly being loaded and unloaded. | 
After the wheels come back from being heat-treated, they go through the first phase of machining to deburr all imperfections and excess aluminum. | 
The final milling is also computer-activated, using one of six CNC milling machines. Hand-polishing the wheels also takes place at this time, in preparation to go to the chrome shop. |
A critical procedure in the making of a wheel is the leak test done with this vacuum-pressurized machine. | 
Before your little minds start conjuring up images that we don't want to talk about, let us explain. | 
Once a tire is mounted on a wheel, you want the best fit possible. |
This test checks for any imperfections, dings, or dents, or the rare occasion that the wheel may be out of round, which may cause a tire to leak air. | 
Voila! Here is the finished product back from the chrome shop. After a final polishing, the wheel is ready for shipment to the many distributors across the country. Here, Vickie does the final quality control test on the new 24-inch IROC wheel. Who says that size doesn't matter? | |
