The latest in the Yellow line takes all of the RSL29 characteristics and adds a bit more aggressive behavior. Friction levels go up for more initial bite and better fade resistance. Modulation and release stays close to RSL29 levels. Pad and rotor wear is a little more than on the previous Yellows but still within reasonable levels and the RSL1 is still considered an extended endurance pad. Its development stemming from GT classes at Le Mans and Nürburgring.
Since Pagid pads tend to "out-gas" we recommend using these pads with a new gas-slotted or cross-drilled rotor for the best performance. Pagid brake pads are not compatible with previously used rotors, especially if used with a carbon or Kevlar based race pad.

Looking to free up horsepower and upgrade your cooling? Then this Electric Fan Conversion kit is the perfect choice! The fan and clutch that connect to the water pump add additional rotating mass to the drive line. By removing them and converting your system to an electric fan, the engine has to do less work, giving you that extra little bit of power. In this kit we include a lower temperature thermostat, coolant additive, and low temperature fan switch that engages the electric fan at a lower temperature, keeping your engine cool and lowering the drag and unneeded weight from the front end of your BMW.
Included in this kit:
