Formula Junior

• Note on realism: Formula Junior is a vintage front-engine open-wheel car (1950s/60s spec) with narrow treaded tyres, minimal aero, and a live/simple rear axle in most AMS2 implementations. Values below are calibrated to that car class, not a modern F-car — treat AERO section as minimal/fixed-device since this car has negligible adjustable aero.

TYRES

• Compound: Medium (only compound typically available for Formula Junior)
• Front: 1.78 bar
• Rear: 1.72 bar
• Tyre blanket temp: N/A (no heaters for this class) — target running temp 75–85°C

ELECTRONICS

• TC: N/A (not fitted — vintage car)
• ABS: N/A (not fitted — vintage car, no ABS confirmed)
• Engine Braking: Fixed/mechanical, no adjustment
• Brake Bias: F: 56% / R: 44%
• Brake Pressure: 92%

DRIVETRAIN

• Fuel Map: Map 1 — full rich, max power for race pace (no lean map needed, small tank/low consumption car)
• Gear Ratios (4-speed, fixed final drive typical of era):
• 1st: 2.95
• 2nd: 1.94
• 3rd: 1.43
• 4th: 1.11
• Final Drive: 4.10

SUSPENSION

• // FRONT
• Ride Height: 78 mm
• Wheel Rate FL / FR: 18500 N/m / 18500 N/m

• Brake Torque Multiplier: 100%
• Brake Bias: 56%
• // REAR
• Ride Height: 82 mm
• Wheel Rate RL / RR: 16500 N/m / 16500 N/m
• ARB: 8 N/m

DAMPERS

AERO

• Front Wing: N/A (no adjustable aero device fitted)
• Rear Wing: N/A (no adjustable aero device fitted)
• Downforce Level: Minimal — bodywork only, no active aero
• Brake Ducts: Fixed, no adjustment

KEY SETUP NOTE

• This car has no aero grip and narrow vintage tyres — stability at Nordschleife's high-speed sections (Flugplatz, Schwedenkreuz, Kesselchen, Döttinger Höhe) comes entirely from mechanical balance and ride height control, not wings. Keep ride height slightly higher than a modern car would run to avoid bottoming through Fuchsröhre's compression and the Brünnchen bumps, as there's zero aero penalty for doing so — pure mechanical grip and smooth inputs will outperform aggressive stiff setups here.

TRACK GUIDE

• Brake earlier and more progressively than modern cars demand — narrow tyres and no ABS mean locking a wheel at Adenauer Forst or the Karussell entry costs several tenths instantly.
• At Karussell, stay smooth and use the banking fully; this car's low grip rewards a patient, rolled-speed approach over late aggressive braking.
• Through Flugplatz and Schwedenkreuz, keep the car settled mid-corner — any mid-corner throttle lift unsettles the light rear end at speed, so commit early and steady.
• Traction out of Adenauer Forst's hairpins and out of the Karussell is where lap time is won — unwind the wheel progressively, as wheelspin with this low-torque engine is costly but easy to control if smooth.
• On Döttinger Höhe, tuck in and hold a straight line — this car's low top speed means every bit of drag or steering correction compounds badly over the long straight.
