LRP X22 WorksTeam optional rotors
Coming from LRP and made for the new X22 series of 540-size competition modified motors are a total of five WorksTeam optional rotors. Available as 12.1mm, 12.3mm, 12.5mm, 12.7mm and 13.0mm variant, the rotors have great influence on the overall RPM and available torque, with the smaller diameters increasing the RPM at the expense of lower torque, less powerful brakes and higher motor temperatures while the larger diameter items reduce the overall RPM but increase torque and brake performance. This means smaller diameter rotors are better suited for 2WD cars or lower grip tracks while the large rotors will excel in 4WD vehicles or on high-grip surfaces. All rotors are direct replacements and they come with laser-etched markings for easy identification.
