With the release of the new G8x M3/M4 IND’s mission is to reduce the amount time needed looking at countless threads to see what spacer sizing is recommended.

Spacers are similar to aftermarket wheels with regard to opinions; everyone has different preferences and tolerances. We prefer the more subtle look with zero-wheel poke - our favorite setup on the new G8X is a 15mm front and 12mm rear.

We will continue to update this thread as more suspension options arrive to market.
