The MM Bumpsteer Gauge is an essential tool for measuring, adjusting, and correcting bumpsteer.
"Bumpsteer" is when tires steer themselves because the toe setting changes as the suspension moves up and down.
Not just for Mustangs! The newly revised Reference Plate fits most 4-lug and 5-lug hubs, allowing use on many non-Ford vehicles. It still fits 1979-current Mustangs, including the rear of the 1999-2004 Cobra with IRS.
