A device, often software-based, helps determine the impact of introducing supplemental hardware between the wheel and the hub mounting surface. This calculation addresses how such additions alter the wheel’s position relative to the vehicle’s suspension and body. For example, it can forecast how much a wheel will extend outwards, given a specific thickness of the added component.
The significance lies in enabling precise modifications to a vehicle’s stance and handling characteristics. Such adjustments can improve aesthetics, increase clearance for larger brake systems, or correct wheel fitment issues arising from aftermarket suspension components. Historically, these calculations were performed manually, making them prone to error and time-consuming. The advent of digital tools has streamlined the process, improving accuracy and efficiency.
