“The general rule in rain driving is to drive where everyone else hasn't. In other words, off the ideal line. The idea is to look for, and use, the grippiest pavement. Through years of cars driving over a particular part of the track, the surface becomes polished smooth and the pores in the pavement are packed with rubber and oil. That is exactly where you do not want to be in the rain.”
Ultimate Speed Secrets — Ross Bentley
Portland's Pacific Northwest climate means rain is a frequent factor. Bentley's rain line principle is essential here: in the wet, avoid the rubber-clogged dry line and search for grip on the cleaner pavement. At Portland, this often means using the outside of corners where the surface is rougher and less polished. Develop a separate rain line for the entire circuit — you will use it regularly.
“In a long braking zone, threshold braking from top speed down to the maximum speed the car will take at the turn-in point is the fastest way. The first step is to push harder and harder on the brake pedal to identify where the threshold is.”
Going Faster! — Carl Lopez (Skip Barber)
Portland's Festival Curves and T12 feature strong braking zones that test brake technique. Lopez's "Procedure" for developing braking performance applies directly — the flat terrain and consistent surface (when dry) provide excellent feedback for calibrating your threshold. The chicane adds a multi-direction braking challenge that rewards precise pedal modulation through weight shifts.
“Rain does not call for a basically different driving technique. The only difference is that grip is reduced, calling for more delicacy when accelerating and braking, reduced cornering speeds and care to avoid pools of water likely to cause aquaplaning.”
Sports Car and Competition Driving — Paul Frere
Portland sees rain frequently in the Pacific Northwest climate, making Frere's wet-driving philosophy essential. His point that the technique is not fundamentally different — just more delicate — is liberating for drivers intimidated by rain sessions. The same braking zones, turn-in points, and throttle application principles apply; they simply require smaller inputs and wider margins. Use Portland's frequent wet sessions to develop rain confidence that transfers to any track.
