F302 Alfa Romeo 155 Ts Fwd

• I'm not certain which tabs and scales the F302 Alfa Romeo 155 Ts FWD exposes in Assetto Corsa. The in-game setup screen decides what you can touch. The values below are my best estimates for a 1990s DTM-style touring car with full tyre, suspension, damper, aero and drivetrain tabs. Anything the setup screen doesn't offer, skip.

TYRES

• Compound: Slick (Medium if offered, Soft for a short stint)
• Front: 26.0 PSI cold, settling to ~29.5 PSI hot
• Rear: 24.5 PSI cold, settling to ~28.0 PSI hot
• Check the in-game tyre app and aim for the middle of its optimum band, since the real target is the car's own band.
• Tyre blankets: not a car setting. Assume off, so the first flying lap is a warm-up lap.
• Camber: Front -3.2°, Rear -2.0°
• Toe: Front -0.10° (toe-out), Rear +0.15°
• Caster: 7.0° (if adjustable)

ELECTRONICS

• TC: not fitted to this car (period touring car), skip
• ABS: not fitted, skip
• Engine brake / brake magic: not applicable
• Brake bias is under SUSPENSION below

SUSPENSION

• // FRONT
• Ride Height: 50 mm
• Wheel Rate FL / FR: 78,000 N/m / 78,000 N/m
• ARB: 42,000 N/m
• Brake Torque Multiplier: 100%
• Brake Bias: 60%
• // REAR
• Ride Height: 56 mm
• Wheel Rate RL / RR: 52,000 N/m / 52,000 N/m
• ARB: 18,000 N/m
• Diff Preload: 60 Nm
• Diff Coast: 0.30
• Diff Power: 0.55

DAMPERS

AERO

• Front splitter: 3
• Rear wing: 5
• Downforce level: moderate. Trim the rear wing by 1 step if you are fighting a straight-line speed deficit on the long run to Riches.
• Brake ducts: 3 if offered, to protect the brakes over a race distance

KEY SETUP NOTE

• A front-wheel-drive car at an aggressive style will understeer on throttle and burn the front-left tyre on Snetterton's long right-handers. The stiff front ARB paired with a soft rear ARB and rear wheel rate lets the rear rotate on lift-off and trail-braking, while the diff power at 0.55 stops the inside front wheel spinning out of Coram and Murrays. Run extra front cold pressure only if the hot reading overshoots, and watch the front tyres over a long stint.

TRACK GUIDE

• Riches and Montreal: Brake late for Riches, trail-brake to the apex to rotate the nose, then get on the power early and let the diff pull you out.
• Oggies and Hamilton: Use the sweeping right-hand sequence to build speed, but avoid sawing at the wheel, because FWD understeer will scrub the front tyres and cost you over a stint.
• Coram and Murrays: A hard braking zone into Coram where you can use the kerbs for rotation, then carry throttle out of the left-hander to protect the exit onto the back straight.
• Tyre and fuel management: Lap time is won in the technical section and lost by overheating the fronts. Back off a touch on the long rights in the second half of the stint, and size fuel to the race laps plus a small margin, since the car burns fuel by the lap.
