Fitment: Miata 1.8 NB (spec Miata) - Rear
Pad thickness: 12.5mm
The PAGID RS29 (Yellow) is the world-leading endurance brake pad used by most of the winning teams in motorsport. The racing compound combines the outstanding wear rate of the RS19 with a slightly higher coefficient of friction and initial bite. Based on the RS14, A slight reduction of the friction value improves the modulation (controllability). Nevertheless, the friction value is enough for cars without power-assisted brake system and ensures comfortable low effort on the brake pedal. Constant temperatures up to 600 C (1,100 F) are possible. This combination of friction value, fading stability and low wear rates on pads and discs (rotors) is unmatched. Due to its excellent release characteristics and controllability PAGID endurance materials are also often used for sprint races.
Pagid RS29 with a very similar friction coefficient to RS19 with improvements in initial bite offering quicker response and slightly more temperature stable at the upper levels of the temperature range. Developments in raw material selection and compounding have resulted in improvements also in pedal feel and feedback, helping with modulation particularly on lighter applications.
This material provides very good levels of performance and response at all temperature levels, only slight temperature inputs are required to bring the pad up to its optimum performance level. Another favourite with endurance racers having won many classes at all major endurance events, such as Le-Mans, Daytona, Spa, Nurburgring, etc. Due to the exceptional pad life and very low wear on brake discs it has been possible to run 24 hours without a change of pads or discs. Able to withstand slightly higher disc temperatures than RS19, this has proved more suitable for applications running very high disc temperatures.
Although designed primarily for endurance racing, because of the consistent levels of performance and user friendliness many competitors use this material successfully for sprint and short distance races also. RS29 has also found favour in the growing track day market due to the level of control, good cold performance, long life and low disc wear.
RST 4 is a semi metallic resin bonded material containing steel fibers. This material has a medium friction level and high temperature resistance.
Applications for the RST 4 compound include formula cars and open wheel racing. Rear axle material for Rally (tarmac and gravel) and for all front engine cars. Also used in NASCAR on long ovals.
