Which (e.g., RX, drifting, historic) are giving you the most trouble? Are you racing on PC or console ?

The foundation of a great handbrake feel is the hardware itself. If you are using a button on your steering wheel or a cheap digital lever, you will struggle with consistency. Switch to an Analog Handbrake

Ensure you have your handbrake axis set to "Button" vs "Axis" correctly in the AMS2 control settings. For hydraulic handbrakes, setting it as an Axis allows you to feel that superior progressive locking physics that AMS2 excels at.

A stiffer rear end reduces body roll and causes the rear tires to lose lateral grip faster under handbrake load.

: For budget or DIY handbrakes (like Arduino-based ones), many users found success mapping the axis through SimHub's Controller Mapper to make it visible to the game. Reiza Studios Forum 2. Calibrate for Linearity

Use a "Custom Wheel" profile to more easily map and calibrate third-party USB handbrakes.

If the car features a hydraulic handbrake linked to the main brake bias, bias the pressure slightly more toward the rear.

: Increase your overall brake pressure if the rear tires refuse to lock on dry tarmac.
