Speed Is Mostly Driver, Not Car
It's tempting to reach for the credit card when your lap times plateau. A new exhaust, stickier tyres, or a limited-slip differential all promise faster times. And they can help — but at the amateur and club level, the driver accounts for the vast majority of available time. Before you spend money on hardware, spend time on technique.
1. Master Your Braking Points
Braking is where the most time is lost and found. Most drivers brake too early and release the brake too quickly. The optimal technique is:
- Brake late, but not too late: Push your braking point forward progressively as confidence builds. Even 5 metres of extra road before braking translates directly to lap time.
- Threshold braking: Apply brake pressure to just below the lockup point, maintaining maximum deceleration throughout the braking zone.
- Trail braking: Gradually reduce brake pressure as you turn into the corner. This keeps weight over the front tyres, maintaining front grip and enabling a tighter line.
Video your braking zones using an action camera. Watching footage back often reveals how early you're actually braking compared to what you felt at the time.
2. Fix Your Exit Speed, Not Your Entry Speed
Corner entry looks dramatic and feels fast. Corner exit actually determines your speed for the entire following straight — which is where you spend most of your lap. The principle: slow in, fast out.
A patient entry that hits the apex correctly allows full throttle earlier on exit. An aggressive entry that overshoots the apex forces you to wait on throttle — costing you speed for the next several seconds. One well-executed exit can be worth more than perfect technique in the corner itself.
3. Optimise Tyre Pressures
This costs nothing and can be worth several seconds per lap. Tyres generate heat during a session, and pressure rises significantly from cold. The correct approach:
- Record your cold tyre pressures before leaving the pits.
- Complete a representative flying lap and return immediately to measure hot pressures.
- The ideal hot pressure varies by tyre and car, but many road-legal track tyres perform best between 30–34 psi hot.
- Adjust cold pressures to achieve your target hot pressure. This is often a trial-and-error process over a few sessions.
4. Use Data Logging
Even a basic data logging app on your smartphone can reveal patterns invisible to feel alone. Apps like Harry's LapTimer or AiM's mobile tools record GPS position, speed traces, and acceleration data.
Overlay two laps and you'll immediately see exactly where you're losing time — a specific braking point, a compromised corner exit, or wheelspin under acceleration. Data removes guesswork and shows you precisely where to focus your improvement effort.
5. Improve Car Setup Before Buying Parts
Before spending on upgrades, ensure the car's existing setup is optimised. Many drivers run the factory suspension setup, which is tuned for comfort — not lap times.
- Corner weights: A properly corner-weighted car handles more predictably and consistently.
- Alignment: A track-oriented alignment with increased negative camber improves cornering grip significantly. A good alignment shop can do this for modest cost.
- Damper adjustment: If your car has adjustable dampers, stiffer compression settings reduce body roll and improve turn-in response.
- Anti-roll bar settings: Adjusting front/rear roll stiffness balance can transform understeer/oversteer behaviour without new parts.
The Honest Truth About Lap Times
Genuine lap time improvement requires consistent, deliberate practice over multiple sessions — not a single breakthrough moment. Keep a session log: note your fastest lap, conditions, tyre temperatures, and what you specifically worked on. Progress compounds. Stay patient, stay analytical, and the times will fall.
