Aero Downforce Balance Calculator
Enter your front and rear downforce figures to instantly see total downforce and your aerodynamic center of pressure (balance).
For most RWD track cars, a 40% Front / 60% Rear aero balance is a stable starting point to prevent high-speed oversteer.
Aero Numbers Are Contextual
Aerodynamic downforce values depend on speed, setup, and aero components. This tool provides balance percentages from raw front/rear downforce inputs—use as a design reference and validate on-track.
Methodology
Computes front/rear percent from supplied downforce values. Does not simulate lap-by-lap aero interaction or ride-height sensitivity.
Frequently Asked Questions
What's ideal aero balance for track driving?
Most prefer 40-60% front downforce (rear-biased for stability). High-downforce setups: 30-40% front. Low-downforce setups: 50-60% front. Adjust for track + driving style.
Does aero balance affect braking and acceleration?
Yes. Front-biased aero = nervous braking; need optimal brake bias tuning. Rear-biased = loose feeling on power. Both corners affect overall chassis balance.
How do I measure actual aero balance on track?
Use telemetry to compare brake pressure (front vs. rear), throttle position, and steering input. If front tires are locking first, increase front downforce or reduce brake bias.
