RDX - White Delrin Spool Cup EX for RDX (2 pieces) Drive Cup [Topline] TP-685

This spool cup is ideal for drift driving that takes advantage of delicate throttle control. It improves throttle response and acceleration. Traction changes during acceleration and deceleration are transmitted linearly, resulting in faithful control performance! The Delrin material, which is highly rigid yet has appropriate flexibility, balances the durability of the drivetrain with smooth movement. Since it can be installed without using a protector, it provides a more direct drive feel.
