Setup Masterclass: Aerodynamics, Dampers & Sim-Specific Physics
Verfasst: 27. Mär 2026, 15:06
A setup is not a cheat; it is a tool. Depending on the simulation (ACC, iRacing, LMU), the physics react differently to your changes.
1. Aerodynamics: The Invisible Grip
•
Rear Wing: Increases downforce at high speeds.
iRacing Specialty: Here, "Drag" (air resistance) is extremely punishing. One click too much wing often costs you 5-10 km/h on the straights.
ACC Specialty: The wing works closely with the Diffuser. If the rear is too high (Rake), the underbody loses its effectiveness.
2. Suspension & Dampers
•
Low-Speed Bump/Rebound: Controls the "roll" and "pitch" of the car during turn-in and weight transfer.
•
High-Speed Bump/Rebound: Controls impacts from the track (Kerbs/Bumps).
Pro Tip: If the car bounces when driving over the "Sausage Kerbs" in Monza, you need to open the Fast Bump setting (make it softer) so the damper can absorb the impact before it lifts the entire chassis.
3. Brakes & Tyres
•
Brake Ducts: Crucial in Le Mans Ultimate (LMU) and ACC. Brakes that are too cold have no "bite," while brakes that are too hot cause the tyres to overheat.
•
Tyre Pressure: In ACC, the window is tiny (26.6 - 27.0 PSI). In iRacing, the window is wider, but the tyres "glaze" or overheat chemically much faster if pushed too hard.
