Check Your Wheel and Hub Setup Before Ordering

This 78 mm conversion kit uses M14 × 1.25 at the hub and M14 × 1.5 for the wheel nuts. Confirm your hub thread and wheel fitment before choosing this conversion. The kit is for a five-lug, four-wheel setup.

Select your nut style from the options above. Confirm the nut seat matches your wheels and that your wheel’s lug openings allow the selected socket size. The manufacturer lists support for spacers up to 20 mm; confirm your complete wheel and spacer setup before ordering.

Contact Kies Motorsports with your vehicle, wheel model, and spacer thickness if you need help selecting the kit.
