Stop Guessing. Log Your Grip.
Tire pressures dictate whether your car hooks up or pushes across the rumble strips. The DriveTDX Logbook gives you track-proven chassis management on your phone.
Cold-to-Hot Thermal Delta
Automatically calculates pressure rise across each tire. Identify uneven corner loading at high-speed right-handers like Sebring's Turn 17 or Road Atlanta's downhill Turn 12.
Atmospheric Temperature Sync
Logs ambient temperature, density altitude, and track surface conditions alongside your tire pressures, allowing you to anticipate morning vs. afternoon PSI creep.
Chassis Balance & Stint Notes
Quickly tag your vehicle handling balance (neutral, understeer, oversteer) and log suspension clicks, sway bar adjustments, and pyrometer temperatures in seconds.
Multi-Track Vehicle Profiles
Save distinct setups for Sebring, Homestead-Miami, Roebling Road, and Circuit Florida. When you return months later, your optimal baseline is right there.
