Mevotech Supreme Alignment Shim P/N:MS80004
Dial in rear wheel alignment and help even out tire wear with the Mevotech Supreme Alignment Shim MS250166, a direct-fit replacement for the 2012-2018 FIAT 500. This shim installs at the rear suspension to correct toe angle back toward specification, helping restore proper tire contact and reduce uneven, premature tread wear when the geometry has drifted out of range.
An alignment shim like this one is a common way to recover proper toe settings on the rear axle without replacing larger suspension components. If worn or out-of-spec rear alignment is behind your uneven tire wear or a vehicle that pulls, this shim helps set the toe angle correctly during a professional alignment. Have the alignment measured and adjusted to the vehicle's specifications after installation.
