Selecting the right brake pad for your application can be a difficult task. Going with a street pad at the track or fast canyon road may ruin your day. Conversely, a dedicated race pad may overpower your tires and result in premature triggering of the ABS system, thereby reducing the overall performance of your braking system. At RR-Racing, we have experimented with most of the compounds detailed in the charts below. We can order ANY pad compound available for your application, but based on our experience, we keep the following compounds in stock, as we have found they will meet 90% of our customer’s needs. If you have any questions please do not hesitate to call or email us.
|Pad Compound||Co. of Friction||Temp.||Recommendations/Notes|
|Wilwood BP10||0.40-0.45||Up to 800F||Excellent pad for street performance applications, but not recommended for aggressive track day use. Available for our big brake kits.|
|Wilwood BP20||0.40-0.53||Up to 1100F||Our pad recommendation for someone looking for a dual purpose street & track pad. This pad is not noisy, normal dust levels, and performs well at HDPE track days. Available for our big brake kits.|
|Wilwood BP30||0.60-0.63||Up to 1300F||Due to the extremely high coefficient of friction, we recommend this pad for track day use only with semi-slick or full race slicks. This pad is easy on rotors, and works very well when cold, but we have found that it is simply too aggressive for street tires. Available for our big brake kits.|
|Winmax W1||0.29-0.32||Up to 842F||Non steel material pad, low dust, street use only.|
|Winmax W2||0.32-0.35||Up to 932F||Ceramic based pad, low dust, high performance street use, light track.|
|Winmax W3||0.34-0.37||Up to 1112F||All purpose street/track pad. Increased dust/noise compared to W2’s|
|Winmax W4||0.37-0.40||Up to 1200F||Track pad that can be used on the street.|
|Winmax W5||0.40-0.43||Up to 1382F||Primarily a dedicated track pad, high metal pad not recommended for street use.|
|Endless MX72||0.37-0.47||Up to 1292F||Great pad for both street and track use.|
|Hawk HPS 5.0
|0.40-0.53||Up to 750F||Great overall street performance pad, low noise and dust. This pad is available for OEM applications only.|
|Hawk HP-Plus||0.50-0.56||Up to 900F||HP-Plus is our recommended dual use pad for street performance, autocross, and track days. This pad has a very high friction coefficient that is very consistent across the temperature range. This pad is available for OEM applications and our big brake kits.|
