About High Performance,Brake Pads High Performance Brake Pads. Wilwood brake pads are,the result of a never ending. development process,that dates back to the,company s origin in 1977. The goal has always been,to provide the highest,level of performance for all. categories of competition,and performance driving,For nearly three decades.
Wilwood has been,deeply involved in all,Wilwood Engineering s corporate headquarters. types of motor sports,This involvement includes, more than just hands on experience from expert design and development engineers The. Wilwood development team includes manufacturing specialists field trained technical. application staff and a broad structured network of championship car builders parts. distributors crew chiefs and race teams just like you Their involvement and expertise. have played an integral role in the development and production of Wilwood brake pads. This network can be found at work and competing at tracks around the world on any. given weekend, Over the years Wilwood has developed an extensive information base that has. fueled development of the world s broadest based line of high performance disc brake. products Throughout this time facts and data not casual observation and opinion. have drawn conclusions that neither a single pad compound or compound type can. effectively satisfy all drivers in all conditions To meet the requirements of such a. broad range of racing and sport driving applications Wilwood has developed a. highly diversified selection of,compounds and pads The available. selections provide incremental,changes in friction values.
temperature operating range as,well as other characteristics. that are capable of satisfying,the stopping requirements of. nearly any motor sport,application Proof is evident. in the wide spread use of the,PolyMatrix family of. compounds and several,other specialized application.

Pad Compound Selection Guide,High Performance Brake Pads. Wilwood brake pad compounds are the results of three decades of experience and continual development to. provide optimized braking and driver feel for all types of motor sport and competition applications This. selection guide is intended to provide general characteristics and applications for each compound The graphs. on page 4 illustrate the differences in friction values and temperature ranges On track testing and driver. evaluation however will always remain the determining factor to final pad selection.

Pad Selection Tips, Temperature range and overall friction value are the primary considerations for pad selection The pads must. be capable of maintaining the proper amount of friction for stopping power within the temperatures that will. be realized on the track during the event Then overall wear rate must be considered For most asphalt and. road race applications compounds in the high temperature ranges over 1000 F range are usually necessary. Dirt track drag race and street performance applications usually operate at temperatures between 500 and. 1000 F Keep in mind that these are general ranges and not absolute values Many factors and unforeseen influences can affect brake. temperatures The best indicator for pad selection will always be on track performance If pad fade friction loss due to overheating occurs. then improved cooling a heavier rotor or a higher temperature range pad may all become necessary.
