Getting your Hypercar setup right at Le Mans is not about chasing the fastest qualifying lap. It is about building a car that is stable, consistent and kind to its tyres at three in the morning when the grip is different to what it was at noon.
This guide covers every setup consideration you want to make when building your hypercar setup for the Le Mans 24h. This guide won't give you exact parameter values, but more so the understanding to find them yourself.
Wing
Le Mans is the lowest downforce circuit in WEC. You are spending a significant portion of every lap at maximum speed, and too much wing costs you time on every straight across 24 hours.
Run the lowest rear wing that still gives you confidence through the fast sections. Ideally, the rear wing angle shouldn't be higher than 3. The main corners where a low rear wing angle may be an issue is the Porsche Curves. Counteract any aerodynamic imbalance with the anti-roll bars. Especially when the car is oversteery: stiffen the front ARB or soften the rear.
Ride height
Lower ride heights reduce drag and increase downforce but make the car more sensitive to bottoming out on the straights. Three ways for you to figure out of the car is bottoming on straights:
- You can hear the floor of the car hit the ground as you get closer to top speed.
- You suddenly start losing laptime in the straights on your delta, when you were running higher ride heights.
- In the telemetry data, your ride height data channel shows zero ride height spikes over multiple bumps.
Rake (the difference between front and rear ride height) affects the overall balance of the car a lot, but also influences the dragen om the straights. For the 24 Hours, moderate rake is the safer choice. High rake setups are harder to manage due to higher rear tyre wear and the increased rear ride height increases drag on the straights. If the car feels nervous in the medium and high speed apexes, reduce the rear ride height to create more stability. Having less rake helps with acceleration on the straight, as the front and rear ride heights equalize earlier, creating the least amount of drag.
Spring stiffness
Softer springs can give more mechanical grip and are more forgiving over bumps and kerbs. Go too soft, and you might be bottoming the floor of the car on the straights. Try going as soft as possible on the springs, without creating a car that bottoms. Stiffer springs may make the car easier to keep within an aerodynamic window on the straights, but also they also increase tyre heat and tyre wear due to less absorption of the bumps by the spring and damper and more by the tyres.
Anti-roll bars
The ARB's are your best friend when tuning the balance of the car around Le Mans. Stiffer front ARB increases understeer on entry and high-speed stability. Softer front ARB moves the lateral load distribution and improves responsiveness but reduces stability through fast corners.
Stiffer rear ARB can cause oversteer on exit. Softer rear ARB improves traction and exit stability.
Brakes
Set brake bias as far rearward as the rear allows without instability, then 1–2 clicks forward as your baseline. Move it progressively forward if the car starts displaying oversteer during the stint.
Leave brake migration at 2.0F–2.5F and do not touch it during the race. The long, high-speed braking events at Le Mans — hard initial braking at high aero load, then a long trail to the apex — are exactly the scenario migration is designed for.
Camber
More negative camber improves cornering grip but increases tyre wear. For the 24 Hours of Le Mans, run less negative camber than you would on a track like Qatar for example.
Having less negative camber improves the straight line grip as well (braking and acceleration) due to the larger contact patch.
Toe
Slight front toe-out increases turn-in responsiveness. Too much makes the car nervous on entry and increases front tyre scrub. Stay conservative at Le Mans. A more neutral front toe reduces tyre wear and scrub on the straights.
More rear toe-in gives stability under braking and on corner entry at the cost of mid-corner rotation. For the 24 Hours, lean toward slightly more rear toe-in than a sprint race. Rear stability at night, in variable conditions, and on worn tyres is worth more than the marginal rotation gain. Make toe changes in very small increments.
The rig that makes setup testing consistent
Finding the right setup requires consistent feedback. If your cockpit flexes or your seating position shifts between sessions, the information you get from the car changes with it — and you end up chasing setup variables that are actually cockpit variables.
A rigid rig keeps your seating position, pedal distance, and wheel angle identical across every session. When the car feels different after a setup change, you know it is the setup.
- SIMGASM Hobby — consistent cockpit feel at an entry level price.
- SIMGASM Club simulator — 80×40 profile, adjustable for any Hypercar wheel and pedal setup.
- SIMGASM Sport simulator — stronger wheel mount, integrated cable pass-throughs, dialled in for long endurance sessions.
- SIMGASM Pro simulator — 160×40 profile, zero flex. Consistent from lap one to lap two hundred.
For brake feel — where bias, migration, and duct changes become things you can actually feel rather than just read — a load cell brake like the MOZA CRP2 gives you the precision to notice when the balance has shifted. You cannot feel that through a potentiometer pedal.
FAQ
Should my Le Mans setup be different from my sprint setup?
Yes — significantly. Softer springs, slightly more wing, more rear toe-in, less negative camber, and more conservative ride heights. The priority shifts from maximum single-lap performance to consistency and tyre management across changing conditions.
How do I know if my camber is wrong?
Check the tyre temperature spread. Inner edge significantly hotter than the outer means too much negative camber. Aim for an even spread across the full tyre width.
How often should I adjust brake bias during a race?
Every stint. Move it progressively forward as front tyre wear increases. Small changes of 1–2 clicks via the MFD rather than large swings.
