Since the floating seats are not fixed, they can effectively prevent your beautiful wheels from being scratched by the bolts.

When it comes to extended wheel bolts for wheel spacers, the thread engagement length is critical. There is a golden rule: at the minimum, thread engagement length must be equal to or greater than the diameter of the fastener. If you install 10mm spacers, simply add up 10mm to the stock bolt length, the result value is the length of the extended bolts. (OEM bolt length + spacer thickness = extended wheel bolt length). BONOSS offers a full line of extended wheel bolts to suit your new wheels or wheel spacers, lengths from 27mm to 75mm.
