Hawk’s Website If you’re looking for the characteristics of various compounds and the temperature operating ranges, look no further than Hawk Performance Product’s website. “On our website, we have a description of all our motorsports brake compounds,” says Motor-sports Sales Manager Edwin Mangune. “It describes how they feel and what you should use them for. ” You’ll learn why you probably don’t want DTC-70s on the Honda Civic you use for autocrossing, and why you might want them on your road racing Camaro. ipad/iphone users click here.

COM/MOTORSPORTS/ an infrared temperature gun,” says Hawk Performance Prod-ucts Motorsport Sales Man-ager Mathew Roskey describ-ing the other method. “I shoot the rotor itself to obtain the temperature. Unless the team rents the track for testing, it’s very hard to come into the pits hot, but that would be the best way, to come in hot and then quickly shoot the rotors. Typi-cally they will do a cool-down lap and the temperatures will decrease, but it’s a start.” Professional motorsports in-frared temperature gauges can start at around $140, but usu-ally an infrared thermometer of the type used in cooking, or the basic model from the hardware store will provide a pretty good baseline for much less. Just make sure it has an adequate temperature reading range. 57 MEASURING BRAKE TEMPERATURES >>> There are two basic meth-ods of measuring brake tem-peratures, and which method you use can depend on both cost and the immediacy of measurement. One is temperature, or ther-mal, paint. The paint is applied to the outer edge of the rotors (where it won’t be swept away by pad contact) and typically has three colors, each of which changes at a different temper-ature. Temperature paint will give information on the range in which the brakes are operat-ing, but not an exact measure-ment. The advantage is that measurement doesn’t have to be taken immediately as the car comes off the track – often an impossibility during race weekends. “The way I like to do it is use Thermal paint changes color at different temperatures, allowing you to know in what range your brakes are operating.
