This molded composite steering block is made from specially-formulated graphite composite material is a perfect balance between reliability and performance. Compact yet rugged steering blocks are molded from a special composite mixture for maximum strength, perfect for high-traction conditions. The graphite steering blocks make the car more stable and increase cornering speed.
For maximum drivetrain reliability, larger 5x12mm ball-bearings are used in the outer position with increased dynamic load. On the inner position, smaller 5x10mm ball-bearings are used to minimize unsprung weight.
