Consistent Performance for Track and Endurance Use
The PAGID Racing RSL 29 is one of PAGID’s most established endurance compounds. It is designed to deliver predictable braking performance over long sessions, repeated heat cycles and sustained high-temperature use.
Rather than producing an overly aggressive initial response, the RSL 29 provides a controlled and progressive braking characteristic. This makes it easier to accurately manage brake pressure during corner entry, trail braking and threshold braking.
The result is a pad that offers the driver confidence and consistency without making the braking system unnecessarily difficult to modulate.
Excellent Modulation and Release
Brake pad performance is about more than outright stopping force. A pad must also respond progressively as pressure is applied and release cleanly as the driver comes off the brake pedal.
The PAGID RSL 29 compound is known for its strong modulation and release characteristics. This allows the driver to make precise adjustments to brake pressure, helping maintain vehicle balance during demanding track driving.
These characteristics make the RSL 29 especially well suited to:
Designed for the AP Racing CP9660 Caliper
These brake pads use the correct profile for the AP Racing CP9660 Pro5000R six-piston caliper.
The CP9660 caliper uses a large full-depth pad designed to deliver even pressure distribution and substantial friction material volume. When paired with the RSL 29 compound, it creates a braking package capable of handling sustained track temperatures and repeated heavy braking.
Compatibility
Designed to fit:
These pads may also fit other brake kits that use the AP Racing CP9660 caliper. Always confirm the caliper model and pad profile before ordering.

What Is Included?
Who Are These Pads For?
The PAGID RSL 29 is well suited to drivers who want a dependable track compound with predictable behaviour and strong durability.
They are particularly suitable for drivers who prioritise:
-
Long pad life
-
Consistent performance throughout a session
-
Progressive rather than overly aggressive braking
-
Precise pedal modulation
-
Reliable performance during repeated heat cycles
-
Reduced pad and rotor consumption compared with more aggressive sprint compounds
RSL 29 Compared With More Aggressive Compounds
The RSL 29 generally provides a more progressive and manageable response than compounds designed around maximum initial bite.
This can make it a better choice for endurance racing, longer track sessions and drivers who want a brake pad that is easier to modulate at the limit.
Drivers looking for an extremely aggressive initial bite may prefer a higher-friction sprint compound. For consistent, predictable and durable performance, however, the RSL 29 remains a proven choice.
Bedding-In
Correct bedding-in is essential for maximum pad performance, consistency and service life.
New pads should be bedded onto clean, compatible brake discs using a controlled series of progressively harder braking applications. Avoid coming to a complete stop with the brakes applied while the pads and discs are extremely hot, as this can transfer uneven deposits onto the disc surface.
Where new pads are being fitted to previously used discs, the disc faces should be inspected and prepared before installation.
Important Information
PAGID Racing RSL 29 is a motorsport-focused brake pad compound.
Motorsport brake pads may produce increased noise, dust and cold-temperature friction characteristics compared with standard road pads. Suitability for public-road use and local regulations should be checked before installation.
Professional installation is recommended. The complete braking system should be inspected regularly, particularly on vehicles used for track driving or motorsport.
Frequently Asked Questions
Do PAGID RSL 29 pads fit AP Racing CP9660 calipers?
Yes. These pads use the correct CP3905D54 pad profile for AP Racing CP9660 six-piston calipers.
How many brake pads are included?
The set contains four pads, enough for one front axle fitted with a pair of AP Racing CP9660 calipers.
Are PAGID RSL 29 pads suitable for track days?
Yes. RSL 29 is a proven endurance and track compound designed for repeated high-temperature braking and longer sessions.
Are RSL 29 pads suitable for endurance racing?
Yes. The RSL family was developed specifically around endurance use, with an emphasis on consistency, modulation and wear performance.
Do RSL 29 pads have strong initial bite?
RSL 29 provides a controlled low-to-medium friction level rather than an extremely aggressive initial bite. Its strength lies in predictable modulation, consistency and durability.
Are these pads suitable for road use?
They are primarily designed for motorsport and track use. Racing pads can produce more noise and dust than standard road pads and may perform differently when cold. Local road-use regulations should also be checked.
What brake discs can these pads be used with?
They are designed for AP Racing CP9660 calipers and can be used with compatible iron motorsport brake discs, including the BTCC-style rotor systems used in XC3 brake kits.
Should new pads be bedded in?
Yes. Correct bedding helps establish an even transfer layer on the brake disc and is essential for consistent performance and pad life.
