Choose the Suitable Thickness Wheel Spacers
1.Fender Gap: Measure your wheel gap for clearance.
You will need at least 38mm of fender clearance to prevent the wheel/tire from hitting the fenderliner.
2.Measure the length of their vehicle's OEM/Factory wheel studs. To ensure it doesn't extend past the surface of the spacer.
if the stock studs are shorter to hold the spacer safely, you need to exchange to small size adapters or purchase longer studs yourself.
if they are too long, you should cut them.
