Each wheel that VIP Forged Modular Wheels creates starts life as a 7-inch 6061 billet aluminum billet rod, which has been heat treated to T6 strength, refining structural grain direction along with the wheels spokes. As it heats, the billet rod is placed into a precision die where it is forged using millions of psi of pressure into a raw forging, as specified by VIP's engineers. The result of the forging process is aluminum with a refined crystalline structure, whose grain direction is aligned with the primary load direction of the wheel spokes.
Then, each center disc profile is placed on a lathe and Computer Numerical Control mills, where each design is transferred from 3D CAD-engineered drawing to exact wheel specifications ordered by our valued customers. The center discs are then prepped for finishes that are applied in state-of-the-art downdraft paint booths, which are also cured for durability.
After the finishing is applied, the U.S.-patented rim halves—also manufactured out of aerospace-grade 6061-T6 aluminum—are assembled together with the center disc, using military-spec stainless fasteners and hand assembled, assuring precise results with each and every wheel. The wheels are then tested for proper run-out and meticulously inspected before finally being delivered to customers. All wheels that we manufacture exceed SAE-J2530 fatigue/rolling resistance and CASS corrosion testing standards, further demonstrating our high manufacturing expectations for VIP Modular Wheels. All designs can be manufactured in 19", 20”, 21", 22" and 24" diameters and 7.0"-15.0" widths to accommodate the most popular vehicles on the market today.
A VIP Forged Modular 3-piece rim half begins life as a large aluminum sheet, which is formed using a CNC spinning lathe. The forming (or spinning) process imparts considerable energy into the aluminum, further refining and orienting the crystalline grain structure in a manner similar to forging. After subsequent heat-treatment processes to achieve a T6 temper, CNC technology is used to machine the inner diameter of the rim half and the assembly holes, so that it precisely mates with the forged center. This is a critical step because the quality of these machine steps relate directly to the final wheel's concentricity. The end result is a highly concentric rim half with the strength properties required to be resistant to the impact and fatigue demands of a VIP Modular 3-piece wheel. Perfection doesn't get any better than this!
Finite Element Analysis (FEA) is an advanced computer analysis tool that allows VIP Modular's engineers to accurately analyze the strength and stiffness of our wheels in the virtual world before they are ever installed on your vehicle. Every wheel undergoes countless hours of FEA, as we meticulously fine tune the design to meet the required strength, fatigue and stiffness requirements, while minimizing mass and rotational inertia. We often deal in increments of 0.25mm, or 1/10 of a degree, when fine tuning designs, and all of this occurs before a single prototype is ever cut.
VIP Modular understands that most automotive enthusiasts look for style when buying wheels, as well as performance and quality. However, VIP Modular provides all this and more when manufacturing our wheels. Strength and fatigue resistance are critical to ensure a VIP wheel lasts the lifetime of your vehicle. To achieve this, VIP Modular designs all of its wheels to pass stringent SAE test specifications.
Computer Numerical Control or CNC technology is used for all of VIP' Modular's machining operations. In-house CNC lathes and mills precisely machine every raw forging into a new VIP wheel design. VIP Modular's skilled and certified machinists use the latest Computer Aided Manufacturing (CAM) software to translate each design's solid 3D computer model into a wheel that precisely matches the design created by our engineering team.
