Mishimoto Borne Off-Road 25mm wheel spacers add track width, create brake clearance and help prevent tire rub while keeping the wheel hub-centric, so each spacer acts as a direct extension of the axle hub on front or rear axles. Each spacer is forged from 6061-T6 aluminum and carries pre-installed grade 12.9 steel M14x1.5 studs, with 16 matching grade 12.9 lug nuts supplied. A black anodized finish protects against corrosion, and the kit is sold as a pair with all hardware needed for installation. Trimming the factory wheel studs may be required to prevent wheel interference.
