If the pockets of your wheels wide enough for your studs, you don’t have to cut the studs. If you buy the 20mm (4/5”) or above spacers you also don’t need to cut the studs. But, if you use less than 20mm (4/5”) spacers, you may require cutting your factory studs a bit to make them fit. Wheel pockets depth + spacer thick ≥ stud length, then the spacers will fit perfectly. And, if you meet any problem with the selection, we have a support team that consists of professionals ready to help.
