Pagid RS4-4

A carbon based friction material developed from RS4-2 but with a progressively increasing friction curve, giving it lower friction than RS4-2 below 300°C and higher friction above 300°C. Particularly popular in Porsche Club Racing and has been fitted as OEM on several high performance road vehicles, such as the 993RS and GT2. In road applications this compound exhibits low brake noise.

RS4-4 offers slightly less initial bite and low temperature response than RS4-2 but has the same high levels of controllability. A very versatile pad for use on both front and rear axles, it is also a very good rear pad in conjunction with RS14 / RS15 on front axles of front wheel drive touring cars.

The wear rate of RS4-4 is very similar to RS4-2, but is slightly better in terms of wear at higher temperatures. As with all PAGID materials, disc wear is exceptional and thermal stressing and tension cracks of the disc surface are greatly reduced.

RS4-4 also has extended operating temperature limits which increases fade resistance and allows braking deeper into the corner without wheel lock and fading issues.
