"Magic Numbers" Every Race Engineer Must Know

Have you ever been lost with your race car's setup? When simulation software and track data don't align, how do you find your way back to peak performance? In this video, OptimumG President Claude Rouelle explains the concept of "Magic Numbers"—the four essential Key Performance Indicators (KPIs) that define your car's grip, balance, control, and stability. The 4 Magic Numbers: Weight Distribution Cornering Stiffness (Tire Grip) Distribution Aerodynamic Balance (Downforce Distribution) Anti-Roll Stiffness Distribution Learn why understanding the correlation between these four ratios (always expressed as front divided by total) is 50% of mastering vehicle dynamics. As Claude reminds us: "All simulations are wrong, some are useful." Ground your engineering in the reference numbers that actually correlate to a winning track performance, and discover why working in delta values is more effective than chasing absolute perfection. ___________ Watch our free-of-charge vehicle dynamics lecture taught by Claude Rouelle: https://optimumg-s-school.thinkific.c...
