The following technical information should be used to gather measurements to ensure a proper wheel fit for most applications.
Here are the two key measurements to be considered before buying any type of racing wheels for your race car:
WHEEL WIDTH and WHEEL REAR SPACING
- This information can be determined by measuring the distance between the inner edges of the rim beads. See Illustration "A".
Wheel Rear Spacing (Offset)
- To measure rear spacing, place wheel face down, lay a straight edge or rule across the back of the wheel and measure down to the mounting pad surface. See Illustration "B".
