lugnut pattern 4x110..

what measurement is that 110mm of? is it the distance between 2 holes across from each other? What is the SAE equivalent of 110mm? is it a straight conversion that comes out to something like 4.33 in.? And anyone know what the max backspacing would be on a stock 12a 1st gen?

TIA

110mm is the Pitch Circle Diameter

There for the diameter that the hole centres are aligned on is 110mm

so yes conversion to Imperial (not sure what you mean by SAE) is simply a matter of dividing by 25.4 to covert from millimeters to inches
