The Evo Racing Brake Pad Reference


R-4 Full Race Compound
Designed specifically for heavy-duty motorsports. The carbon based semi-metallic R-4 materials allow the pad to absorb tremendous amounts of heat and dissipate it at very even rate. Carbon Kevlar material warms up to race temperature quickly, which is quite helpful during restarts, and when track time is limited. When used with cast iron and steel alloy rotors, the R-4 compound requires minimal bed-in period. Throughout the entire heat range, the carbon kevlar material will give extremely consistent modulation and predictably. This is truly the most rotor friendly racing brake pad material ever. Good for road courses, oval track, rally, vintage racing, autocross, club events or professional racing events.

R4-E Endurance Race Compound
A carbon kevlar compound made to last a bit longer than the original R-4 compound. The R4-E compound is designed to endure higher prolonged temperature and still has pad life as long or longer than Porterfield R-4 do. This pad is great for club enduro events and applications where temperatures are at their maximum.

R4-1 Vintage Full Race Compound
Developed using knowledge testing in the vintage racing community. Optimum uses for the R4-1, under conditions where very high friction is needed with minimal warm up time and in applications where there is difficulty in maintaining sufficient heat with conventional race pad compounds. Widely used on vintage GT and formula cars the R4-1 is also gaining popularity in off-road and rally-cross classes. Great modulation, consistent pedal feedback and rotor friendly at all temperatures as with all the other Porterfield Carbon Kevlar compounds.

R4-S High Performance Street and Autocross
For high performance and heavy-duty street conditions. Perfect for prolonged everyday street use while also being capable of tolerating the most severe street use without any fade. Rotor friendly of course. The R4-S friction level will give you an impressive increase in stopping ability with very minimum pedal effort. R4-S compound has the absolute lowest noise and dust levels, far below OEM equipment or any other high performance brake material. Good for autocrossing, some drivers schools, solo events, and rally’s. The R4-S compound is available for virtually any vehicle sold in the US. We also offer the R4-S in pad sizes for competition type calipers that are used under street driven conditions.



ST41 – The best high energy input racing material available. Maintains high mu level at extremely high temperatures without sacrificing good wear – both pad and rotor. Needs some heat to work well.

ST42 – Lower mu than ST 41 and ST 43. Extremely stable average and in stop output over a wide temperature range. Has been very successful when used on the rear in conjunction with 41 on the front. Best high-temperature wear of all out materials.

ST43 – Friction level and wear rate between ST41 and ST42. Stability is not quite as good as 42 but better than 41. Should be an excellent open wheel formula. ST38 – Slightly lower mu than ST42. Wear still not as good as ST41. Good Performance over broad temperature range with minimal rotor wear. Successful in a broad range of racing series.

02 Compound – The newest PFC compound offering the highest friction level of all. This also features outstanding initial bite and with great modulation.

01 Compound – 01 has a high flat torque curve, providing excellent pedal modulation. Better pad wear than 83 and faster smoother release. Cold bite comes in at ambient temperature and is effective to over 1200F. 01 polishes the rotor without pad material build up.

99 Compound – Shares the same features as the 97 compound, but with slightly higher torque. These new advanced compounds improve both modulation and release. There is reduced torque rise with temperature with both 97 and 99 compound.

97 Compound – Has a bite slightly higher than 90 compound. Cold bite comes in at 250 degrees and has a moderate flat torque curve. With the flat torque curve the driver now has the ability to turn the steering wheel in the corner while braking. This compound also releases faster than all of the other above-mentioned compounds.

93 Compound – 93 was developed as the next step after 83. The improvements are better release characteristics, great improvement for trailing into a corner or modulation at threshold braking. Kinder to discs. 93 comes on quicker and has flatter torque curve. But, be careful without finesse you can over slow the car. When it comes to ultimate performance with finesse, this is second to none. Cold bite comes in at 250-275 degrees and has an effective torque curve over 1200 degrees.

90 Compound – 90 was developed at the same time as 93 and is very similar with lower torque output. It also has a higher wear rate under severe service. This pad gives three times the pad and rotor life, ultimate torque close to 93. Its modulation characteristics also make it forgiving. Cold bite comes in at 100 degrees and has an effective torque curve over 1000 degrees.

83 Compound – This material has super high torque and gives a firm pedal feel. 83 require finesse. Under sever conditions, it has outstanding wear characteristics. 83’s cold bite also comes in at 400 degrees and has an effective torque curve over 1500 degrees.

80 Compound – 80 is the lowest friction. It has very good wear characteristics and is more rotor friendly than 83. It is more suitable and therefore a favorite for many applications where pedal modulation is difficult or chassis set up or driver development brake balance or others require a more forgiving pad. Cold bite comes in at 350 degrees and has an effective torque curve to over 1000 degrees.

Z Rated Performance Street – The highest friction brake pad available for street vehicles. This is designed for customers who demand ultra high performance braking with low wear, rotor compatibility and fade resistance.



CARBOTECH PANTHER XP10 (1110): For 2004, Carbotech unleashes Panther XP10 (compound 1110). This is an *extremely* high initial bite material, with a friction coefficient well above .6. Fade resistance is in excess of 1600F. Due to the high level of friction and bite, this material is recommended *ONLY* for cars in excess of 2600lbs using R-compound race tires or slicks (SCCA T1, T2, A Sedan, GT1, Trans-Am, Speed GT, etc.). On these heavier cars, 1110 still maintains the excellent modulation that has made the Panther-series of brake pads so popular. It is not recommended to drive this compound on the street or on the track with street tires due to the tendency to easily lock a lower-grip street tire with very little effort due to the high friction coefficient of this material. Note: Compound #1110 is more rotor aggressive than any other 1100-series compound.

CARBOTECH PANTHER XP9 (1109): Another iteration of our successful Panther compound series, 1109 offers even higher initial bite, higher friction coefficient (.6+), and higher fade resistance (1400+F) than 1108 compound, yet still maintains the rotor friendliness and streetability that has made the ceramic-metallic based Panther line so popular. This compound is intended for expert - instructor level HPDE drivers as well as upper level regional and national road-racing (ITA, ITS, Spec Miata, SSC, SSB, FF Cobra, etc) Panther XP9 has already won multiple SCCA regional and national championships in 2003, its first year of release. Not recommended as a daily-driving street pad due to possible elevated levels of dust and noise.**

CARBOTECH PANTHER XP8 (1108): A high torque brake compound with a wide operating temperature range (250F to 1350F). Outstanding initial bite at race temperatures, high coefficient of friction (0.58-0.60), excellent modulation and release characteristics, extremely high fade resistance, very rotor friendly and excellent wear rates. Excellent for ITA, ITB, Spec-RX7, etc race cars. Perfect for intermediate - advanced track/HPED use with R-compound tires, but still can be easily driven to and from the track. Not recommended as a daily-driving street pad due to possible elevated levels of dust and noise.*

CARBOTECH PANTHER PLUS (1106): A high torque brake compound delivering reliable and consistent performance over a very wide operating temperature range (150F to 1250F). Advanced compound matrix provides an excellent initial "bite", high coefficient of friction (0.54-0.56), and very progressive brake modulation and release characteristics. Panther Plus offers high fade resistance, rotor friendliness at all temperatures, and excellent cold stopping power. As a result, Panther Plus is an excellent choice for beginner-novice lapping day and high performance driver's schools on street driven cars using street or R-compound tires, eliminating the need to change brake pads at the track. Panther Plus has gained tremendous popularity with SCCA Prosolo/Solo2 competitors for its fantastic bite and modulation. In addition, Panther Plus has seen great success as a race-only pad on lighter improved touring and vintage race cars (ITC, etc).**Not recommended as a daily-driving street pad due to possible elevated levels of dust and noise.**
