Wilwood's Temperature Strips provide an easy, accurate, and affordable method of recording observed on-track temperatures of brake calipers or other components on a race car. The adhesive-backed strips can be attached to any clean, smooth surface to record peak temperatures that occur during sessions. The temperatures are marked for both Fahrenheit and Celsius with the range of 250° to 536° F and 121° to 280° C. The indicator color changes to black when a new, or higher temperature level is observed. Each package includes 10 non-movable strips.
