Audi R8 LMS (2015)

TYRES

• Compound: Dry (DHE 2024) — front 26.8 PSI, rear 26.5 PSI cold. Account for race-distance pressure rise of ~2.5–3.0 PSI; target hot window 27.5–28.0 PSI front, 27.0–27.5 PSI rear. Tyre blanket temp: 80°C both axles. Optimal operating window for max grip: 85–95°C (core), with peak grip around 90°C — stay aggressive early to get there fast but watch front-left overheating on this clockwise-loaded track.

ELECTRONICS

• TC1: 4
• TC2: 1
• ABS: 5
• Engine Braking / Brake Magic: Medium-low engine braking map (reduce rear instability into T1/T5 hairpins)
• Brake Bias: 56.5%
• Engine Map: 2 (fuel saving for race stint, bump to 1 for qualifying-style push laps)

DAMPERS

AERO

• Front Splitter: 4
• Rear Wing: 6
• Brake Ducts: Front 3, Rear 3 (manage temps over race stint — bump to 4/4 if Castrol/Rindt braking zones show overheating warnings)

KEY SETUP NOTE

• The R8's strong traction out of T9 (Hans Ernst) onto the main straight is your biggest lap-time lever — slightly stiffer power diff lock (0.6) and a touch of rear ARB softness keeps the rear planted on exit without sacrificing the rotation you need entering T1 under aggressive late braking.

TRACK GUIDE

• T1 Castrol Kurve: brake deep and late, but trail-brake progressively — the Audi's stable front end allows late entry; prioritize a clean rotation over max entry speed since exit traction matters more for the lap.
• T3 Schlossgold & T4 Rindt Kurve: committed, near-flat — keep steering inputs smooth; any snap here costs massive time given the high-speed rear-light nature of these corners, trust the aero platform.
• T5 Jochen Rindt: one of the hardest braking zones on the calendar — brake in a straight line first, then rotate; late braking here is a time gain but overcommitting causes lockups given the downhill approach.
• T9 Hans Ernst: this exit defines your entire main straight speed and thus your overtaking/defending opportunities — sacrifice a fraction of entry speed for a cleaner, earlier throttle application.
• Kerb usage: aggressive kerb riding at T6/T7 chicane rewards the R8's stiffer ARB setup, but don't overdo it on T9 exit kerb — unsettling the rear there costs more than it gains.
