ENDURANCE RACE COMPOUNDS

In endurance races, not only must you match with the features of the brakes, but how you will run the entire race distance is also a big issue. In cases of 4 or 6 hour races, it is generally presumed that the brakes will not be changed, but in longer races like 12 or 24 hour ones, planning the number of times you will change the brakes also changes the required type of friction properties, while on the other hand brake features are more important to pursue, making it necessary to compromise.

MA45B and YZ080 are ENDLESS's popular endurance race friction materials.
MA45B is a semi-metallic material and is often used in endurance races in light cars and cars with good chassis balance. It first earned its reputation as a pad which could run the Nürburgring 24 hour race without changing the brakes in the Porsche cup car, etc., and even now it is favored by many Porsche users. As it demonstrates stable function even in races with relatively high loads and has superior friction properties it is used in many GT cars, while in 12 or 24 hour races it cedes this spot to YZ080. YZ080 is a sintered compound material which, although it has a low absolute friction coefficient, it has a sharp initial response and possesses features which are suitable for braking in long-distance races. Coupled with its superior friction properties, this makes it widely used in GT3/GTE cars.

In GT cars where rear wheel lock is a concern, you can use MS20 or ML40A as well, the same as with sprint races.

Semi-metallic materials made for higher loads such as ML35A/40A are suitable for race distances of 5-8 hours and in high load conditions.

The friction speed of a pad will change depending on changes in various conditions such as circuit layout, tires used, air temperature, etc. If considering use in endurance races, it is essential to do tests in advance, etc., to calculate amounts of friction and prepare the required number of pads before racing.
