DAMPERS

AERO

KEY SETUP NOTE

• Portimão's blind crests (Turns 1, 8, and the uphill-downhill transitions through the middle sector) unload the car mid-corner — run slightly stiffer front ARB and lower rear ride height than usual to keep platform stability on crest compression without sacrificing rotation on entry to Turns 5 and 15.

TRACK GUIDE

• Turn 1: brake late on the approach to the blind crest, trail brake lightly over the rise — car goes light here, don't add steering input mid-crest or it'll snap.
• Turns 3-5 (uphill esses): carry momentum, minimize steering corrections, let the car float through — this is a rhythm section, not a braking zone.
• Turn 8 (Curva do Boost, downhill blind apex): commit full throttle on exit blind, trust the aero — lifting costs more time than the risk of running wide.
• Turn 14-15 (final corners): this is where the lap is won or lost — late apex Turn 15 to maximize exit speed onto the front straight, sacrifice min speed for exit traction.
• Kerbs at Turns 1 and 8: ride the inside kerb aggressively on exit to straighten the line, but keep wheels planted — too much kerb strike unsettles the rear on this bumpy circuit.
