Joe's Racing Adjustable Tire Probes are right angle designed to fit the tight fender clearance on your race car. The adjustable tip probes can be set for rubber thickness ensuring you measure temperature down to the cord where the real action is stored.
Tire rubber will be a different temperature based on how deep you insert the probe. For accuracy you need to move quickly and insert probes at a consistent depth at every location. Dial in your camber based on corner performance with the assurance that all tires are measured at the same rubber depth for precision readings.
