DAMPERS

AERO

• Front Wing: 8 (max attack angle), Rear Wing: 9 (max downforce — Tsukuba is tight and twisty, low-speed grip trumps straight-line speed), Downforce Level: Maximum available, Brake Ducts: N/A on this car

KEY SETUP NOTE

• Tsukuba's tight hairpins (Turn 1, Turn 3, Final Corner) demand maximum low-speed rotation — run softer coast diff (0.6) and slightly higher rear ride height split to encourage the rear to rotate on trail-braking; with a formula car's low mass and high downforce, sacrificing a bit of top-speed aero efficiency for max wing angle pays off lap time here since there's no long straight to exploit a low-drag setup.

TRACK GUIDE

• Turn 1 (hairpin after start/finish): brake extremely late, trail-brake deep and rotate the car on entry — exit traction onto the back straight is the biggest lap time gain of the lap
• Turn 3 (tight right-hander): use full kerb on exit, get back to throttle progressively — the diff power setting (0.4) prevents snap oversteer here
• Esses (mid-sector): carry momentum, minimize steering corrections — this is a rhythm section, smoothness beats aggression
• Final hairpin: this is the most critical corner for overall lap time — a clean, late apex sets up maximum speed onto the front straight; any mistake here costs 2-3 tenths minimum
• Kerb usage: Tsukuba's kerbs are aggressive — use them only at Turn 1 exit and Esses, avoid unsettling the car elsewhere given the stiff springs needed for aero platform stability

THEORETICAL BEST LAP

• 0:49.800 — estimated optimal based on combined best sector times, dry track, soft tyres at peak grip window
