The ICM SM (Spec Miata) Toe Stick greatly speeds up the process of checking toe in/out with a string or laser alignment system. No more going back and forth with a ruler to measure toe in or out. Simply hold the ICM Toe Stick up to the wheel and read both sides of the wheel with a quick glance. Designed for use with the ICM Alignment system, this tool can be used with most other laser or string based systems as well. Constructed using 6061 aluminium and CNC machined for accuracy. The wide ruler blocks make it easy to place and hold the tool against the wheel face, providing fast and more consist readings. This unit is desiged specifically for use with the 15" rims used for Spec Miata or other 15" diameter wheels. This model is non-adjustable. If you need an adjustable unit we have that covered as well elsewhere in the catalog. This tool is a perfect complement to the ICM Alignment system or any string based system.
