PAGID RSL 1 Racing Brake Pad (Shape 4931) S4931L01001
Built for endurance racing, the PAGID RSL 1 compound gives stable, repeatable braking over long stints. It offers strong bite, easy modulation, and very low disc wear. Ideal when you need consistent pedal feel and long pad life under high heat.
Track and motorsport use only. Not approved for road use.
Why choose RSL 1
- Endurance-proven compound with consistent friction at high temperatures
- Excellent control and pedal feel for confident trail braking
- Low wear on pads and discs to support long runs
- Resists fade under sustained heavy braking
Best suited for
GT and endurance racing, touring cars, prototypes, and one-make cup cars. Works well on medium to high grip tyres and ABS-equipped cars. For sprint events, some drivers may prefer a more aggressive initial bite (e.g. RST compounds).
