You will need longer wheel studs to safely use a 15mm spacer.
Just to be clear I am talking about spacers like the ones i linked. They bolt to the hub, then the wheel bolts to the pressed studs in the spacer.
The issue is the original studs protrude from the spacer, but by how much for 15mm and will they recess into the wheel pockets of the standard 17 inch lusso wheels?...
My measurements look ok but was hoping someone had done it...before I order
