Anyone know how deep the recesses are on the back side of the OEM 21 inch wheels? It looks like about 1/4 inch deep in the photo. I was wondering if I want to run Bora 1 inch spacers is there enough relief in these recess areas to allow the Bora 1 inch spacers without trimming the factory wheel studs? I am assuming the photo actually shows the back side of a ST 21 inch wheel.
