Acura ARX 06 GTP

The Acura ARX-06 GTP features a sophisticated braking system with adjustable brake pad compounds (Low/Medium/High), independent front and rear master cylinder sizing, and in-car brake bias adjustment via the steering wheel display. The brake lockup LED indicators provide real-time visual feedback: pink lights show front wheel lockup severity, while yellow lights indicate rear lockup, helping you identify bias issues immediately. Three pad compounds offer distinct trade-offs—Low provides maximum modulation but requires deeper braking zones, Medium balances bite and control, while High delivers aggressive initial bite at the cost of easier lockups.

Brake bias setup depends heavily on aerodynamic configuration and track characteristics. The manual defines brake pressure bias as the percentage sent to the front brakes; it should be tuned for driver preference and track conditions, not treated as a universal numerical target. Master cylinder sizing provides coarse adjustment—smaller front cylinders shift bias forward and reduce pedal effort to lock fronts, while rear cylinder changes work inversely.

The car's heave dampers significantly influence braking stability, particularly low-speed compression settings. Higher front compression stiffens the platform under braking but can induce understeer at turn-in, while softer settings improve mechanical grip but may destabilize the aero platform.
