This page explains the principles. It is not a substitute for instruction from a racing school or a sanctioning body's driver education program, and it does not replace the rules and tech requirements of the event you enter.
First laps: follow someone who knows it
The programs below introduce a circuit gradually. At SCCA Track Night in America, as Winding Road describes it, the novice group's first session follows a pace car to learn the line, and instructors debrief each group after its sessions. An IMSA report from Nelson Ledges in 2021 describes five familiarization laps behind a coach. NASA's HPDE Group 1 requires instruction, either in the car or lead-follow, and NASA follows track sessions with classroom debriefs it calls "download" meetings.
SCCA Time Trials sets similar requirements for novices: at least one classroom session on the Rules of the Track, regular contact with instructors, and observation by a Novice Coach or assistant whenever they are on track. It strongly suggests debriefs after each session. More on how these events run is on track days.
Study the track before you drive it
HP Academy recommends walking corners to see them from different angles, and watching onboard footage from professional drivers to learn where the apexes are. It also suggests the most heavily rubbered section of curb as a clue to where the apex sits. Its Race Driving Fundamentals course includes separate modules on track walks, prioritizing corners, visualization, onboard video, simulators and data analysis, which shows how it breaks the job down.
The Porsche Club of America's Northern New Jersey Region classroom material (2025), which describes its techniques as advisory only, recommends labeling every corner on a track map by type and asking why each apex is where it is. Its three types:
| Type | Where it sits |
|---|---|
| Type I | Leads onto a straight (the material calls this type the most important) |
| Type II | Ends a straight, with no straight after it |
| Type III | Sits between other corners (the material calls this type the least important) |
The same material classifies a corner by comparing its acceleration zone with its deceleration zone. A longer acceleration zone makes it an exit-speed corner (late apex); a longer deceleration zone makes it an entry-speed corner (early apex); equal lengths make it balanced. It says most corners on a typical track are Type I, so exit speed usually matters most. The line choices themselves are covered on the racing line.
Which corners matter most
Coaches do not all rank corners the same way:
- Ross Bentley notes that most drivers follow the guideline of prioritizing the corner onto the longest straight, but says drivers who focus on other corners often beat those who follow it.
- HP Academy says the key corner is often a slow one followed by a long straight, and that priority should be decided from data rather than a track map and a few laps. Without a logger, it suggests comparing speed at a fixed point on the following straight while trying different approaches, and calls that a rough method.
- Bentley (Substack, June 2026) argues there is no such thing as a corner that does not matter, warning that overdriving a "throwaway" corner can cost time on the straight after it.
Bentley also says fast turns offer the most lap time to gain (Winding Road, 2020). Reading data is covered on data and video.
Building speed
Driver61 recommends driving at about 80 to 90 percent for two or three laps to learn the car and the conditions at each corner before raising the pace, because information is harder to take in near full mental capacity. Ross Bentley's principles for the sessions that follow (Winding Road, 2018):
- Two or three areas at a time. Pick the parts of the track with the biggest potential gain. More than three, he says, overloads the mind.
- Consistency before car changes. Be consistent at the limit before changing the car in a big way, so you can tell whether a gain came from the car or the driver, and be honest about whether you really felt a difference.
- Time at full throttle. Much of the remaining lap time, he says, comes from more time flat out, including short sections where drivers settle for part throttle.
- Flat-out corners come gradually. Lift well before the corner and be back on the throttle before turn-in, then shrink the lift lap by lap.
On fast turns, Bentley says that braking late or lifting at turn-in leaves the car unbalanced just when it needs grip most, so small speed adjustments should come early, with the throttle back on by turn-in. He also notes that holding your breath tenses the hands and arms and dulls feel for the car. In a 2026 piece he adds that chasing time with later braking usually just means braking harder without a faster lap.
Two further cautions. Bentley (Substack, 2024) separates steering timing (when rotation starts relative to turn-in) from steering rate (how fast and how evenly the wheel turns), and says using one habitual pattern for every corner does not get the most from the car. Colin Braun (2020) says speed comes from hard work rather than "magic" parts or lines, and warns drivers against convincing themselves they felt a change that was not there.

Bentley's book Speed Secrets: Professional Race Driving Techniques (Motorbooks, 1998) covers lines, visualization, practice methods and working with a crew chief, according to its publisher. Where to look while learning a track is covered on vision.
