Offset and Backspace calculation
Almost all Minilite Wheels are cast as blanks and we are able to machine a variety of PCD’s (stud/bolt patterns) and offsets.
The offset is calculated from the centre line of the wheel to the back face of the wheel; a backface in line with the centre of the wheel is zero offset. If the backface is forward of this line towards the front of the wheel it is a positive offset and toward the rear of the wheel from the centre line is a negative offset. Offset can be calculated using the backspace (‘C’ dimension in the following diagram):

Please note: This will calculate the backspace from an offset, but not the reverse. The wheel width to enter is the nominal, see the 'A' dimension diagram to the left.
