What do you do when your race car setup is completely lost?

You go back to your "Magic Numbers"!

In vehicle dynamics, getting lost in setup changes is easy, but finding your way back to peak performance relies on understanding four fundamental Key Performance Indicators (KPIs): Weight Distribution, Tire Grip (Cornering Stiffness) Distribution, Aero Balance, and Anti-Roll Stiffness Distribution.

In this video, OptimumG President Claude Rouelle explains that if you understand how these four fractions interconnect, you’ve already mastered 50% of vehicle dynamics. Stop guessing with your setup and start working with delta values that correlate real track performance.

Watch the full video on our YouTube channel to understand how to apply these metrics and why "all simulations are wrong, but some are useful."

Today we bring a very simple analysis, but it can only be done once the vehicle fundamentals are well established with you.

For this, we have the Applied Vehicle Dynamics Seminar, where you can learn from the basics to the most advanced scenarios in motorsports.

This is the last week to register with a discount for the Applied Vehicle Dynamics Seminar in Adrian, MI, USA, that will happen from June 21st to June 24th.

Don't waste more opportunities to win races just because you don't master your car's behaviour.

One more successful Data-Driven Performance Engineering Seminar in Adrian, Michigan. We had an excellent group of people, interested in taking data-driven decisions. Thank you to all who attended.

Next month, we will still be in Michigan, but now hosting the Applied Vehicle Dynamics Seminar. If you want to deepen your knowledge in vehicle dynamics and understand why your car behaves as it does, this is your chance.

When we test a car on a 4-post rig, we look at the vertical load variations. But what do we actually know about a tire’s vertical stiffness and damping under real track conditions?

Our engineers will tell you that minimizing tire force variation is the ultimate goal for grip. But the relationship between vertical load and lateral grip is far from linear.

If you want to know how excitation frequencies, tire stiffness variations, and non-linearities actually dictate your tire's contact patch behavior under track conditions, this is a must-read.

Are you ready to defend your design?

We are happy to announce that our president, Claude Rouelle will be back at the Michigan International Speedway as a Design Judge for FSAE Michigan IC 2026!

For more than 20 years, Claude has been pushing teams around the world to show their best engineering and vehicle dynamics projects. This is your chance to show the world that your car isn't just a guess—it's engineered for performance.

To all the teams competing: Bring your data, bring your logic, and most importantly, bring your "A" game. We’ll see you at MIS!

Stop saying "Weight Transfer"!

It is one of the most common terminology mistakes in motorsport engineering. As Claude Rouelle explains, weight transfer happens when physical mass moves inside the car (like fuel sloshing or a passenger shifting). Load transfer is about the forces happening at the tire contact patch.

And here is the golden rule:

Displacement and force are NOT the same thing.

Drivers often complain about having "too much roll," thinking it equals high load transfer. But you can have a massive amount of load transfer with almost zero chassis roll angle.

Want to understand the physics behind this and how it affects your anti-roll bar setup?

It's time to understand how OptimumG develops our software!
On April 8th and 9th, we'll present two free webinars about "Structured Approach to Vehicle Dynamics Simulation". 🖥
We'll show you how we approach “simple to complicated” fundamentals at OptimumG. Our engineers will demonstrate how they develop and efficiently use a two-wheel transient model that includes parallel coordinates and a phase portrait.
On the second day, we will show you an example of the abstract approach of Skip pad optimization and also a simple software development on an open-loop 4-wheel model transient load transfer.
You will have the opportunity to ask any questions you want.
We're waiting for you!
