From Core to Curve
A 32-bit processor works seamlessly with the high-precision MEMS gyro to calculate and correct every deviation—delivering control that feels natural and fluid.
Tuned for RWD drift cars with 9 preset curves, and compatible with touring, rally, and short course models.
9 Preset Curves. For Every Drift.
From smooth to sharp, GD-401A’s 9 preset curves adapt to your driving style—beginner or pro.
A single button cycles through modes (1–9).
At startup, green LED flashes display the selected curve.
Adapt to every track. Match every drift.
