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).
Vehicle and caliper compatibility
Pad Shape 4931 is used in selected motorsport calipers from leading brands (e.g. Brembo, AP Racing) and in popular GT and cup platforms. Use our vehicle lookup or check the Vehicle Fitment tab to confirm this shape for your car.

Delivery timescales are given as estimates in good faith, but cannot be taken as precise or exact information. We highly advise against booking installation/workshop time or engaging in preparatory work until you've received and inspected the goods.
What do our stock statuses mean?
1+ IN STOCK in green stock is readily available in one of our warehouses for express delivery (at the time of viewing).
LOW STOCK in green means we're running low! 1 or 2 left on the shelf so act fast. Over evenings, weekends and bank holidays this stock can move quickly so please bear this in mind.
0 IN STOCK in blue means our primary warehouse does not have unallocated stock, but our UK partners do. Often these can be shipped quickly and efficiently. You'll be notified via the Track My Order page if further delays are unavoidable.
MADE TO ORDER in blue means we've partnered with a supplier which primarily makes their products to order. It's not on our shelf, but your order goes into production immediately.
0 IN STOCK in orange means everybody we work with is unfortunately out of stock. Stock is not available in the UK. The best course of action is to place an order to create an allocation from the next batch arriving.
OUT OF STOCK in red. This product is unavailable to order, for whatever reason we're unable to obtain stock or there is an issue with supply/lead times.
We're tuners too!
Our staff are car enthusiasts, we understand the need for speed... This includes getting your orders out the door as quickly and securely as possible!
In some instances, extended lead times are unavoidable. This is as labour-intensive and frustrating for us as it is for you, please know we are doing our best to facilitate your modification goals. Abuse of our staff or systems will not be tolerated.
Thank you, Team PP
In the words of the Vehicle Standards Agency (VCA), type approval provides "confirmation that production and samples of a design will meet specified performance standards".
For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
