Rw Seat Ibiza Kitcar Polocup

TYRES

• Semislick (SM) compound, front 26.5 PSI cold / rear 26.0 PSI cold (targets ~31.5–32 PSI hot front, ~31–31.5 PSI hot rear — session is 17°C air/24°C track per reference lap, no blanket option on this car, expect a slow first lap to build temp)

ELECTRONICS

• TC: 2 (low-medium, kitcar front-drive torque steer control)
• ABS: 4 (moderate, allows late trail-braking without excessive pedal travel)
• Engine Braking: N/A (fixed on this car, no in-cockpit adjustment)
• Brake Bias: 68.0% front (carried from reference lap, correct for a front-biased hot lap setup on cold-to-moderate temps)

DAMPERS

AERO

• No adjustable wings/splitter on this car (fixed road-based aero kit, front air dam and rear lip only) — no setting to give

KEY SETUP NOTE

• This FWD kitcar needs the diff locked moderately on power (0.2) to pull cleanly off Turns 8, 12 and the final hairpin without understeering wide, but kept open on coast (0.4) so it rotates freely into Turn 1 and the fast Turn 8 entry — too much coast lock will push the nose and cost the whole lap through Istanbul's long sweepers.

TRACK GUIDE

• Turn 1: brake hard in a straight line from ~280 kph, trail off the brake progressively — any trail-braking rotation here with a FWD car risks snap oversteer on turn-in, better to brake earlier/straighter and carry mid-corner speed
• Turn 8 (multi-apex esses): this is where the lap is won — commit full throttle through the entry, let the car float slightly wide on exit of each apex, sacrifice a fraction of mid-corner for a cleaner run to Turn 9
• Turn 12 (final corner before pits straight, DRS/launch zone equivalent): traction out of here is critical for the long back straight — get the car rotated early and get on power in a straight line, exit speed matters more than entry speed
• Turn 3-4 (uphill esses): late apex these slightly to maximize exit speed onto the back straight, this FWD car loses more in traction zones than it gains from outright cornering speed
• Brake bias at 68% front suits this car's natural understeer tendency under hard braking — resist the urge to move it rearward for "rotation," it will only induce lock-ups given the Ibiza's chassis balance
