What is the benefit, if any, of having stud replacement spacers versus bolt-on? And if one is better than the other, then why does it seem like some guys have both?
Also, I was going to get 15mm bolt-on Ichiba spacers for the front and 20mm for the rear, but someone else said the 15mm won't fit on the front with the Rays wheels. Is this really true, and if so, which brand would fit?
