TEGIWA Arch Roller Tool. Use this tool to flatten the wheel arch lip to the wing, allowing more room for the tyre. Increase tyre to wing clearance, flare arches or repair wheel arch damage with this professional forming tool. It bolts directly to the hub flange, with elongated holes in the adapter plate to fit all popular 4 and 5 bolt hubs. The forming arm adjusts from 14" to 22" so can be used on most cars. Using a little heat it is possible to fold the inner lip flat without damaging the paint.
