Know your number before you stage. ET predictions from density altitude, wind, and your own runs — with the math shown, never a black box.
TrackR is the bracket racer's data logbook and dial-in predictor — built by racers, for racers.
Log every pass in seconds, let TrackR learn your car, and walk up to the lanes knowing your number. Every ET prediction is backed by real math — no black box.
PREDICT YOUR DIAL-IN
• ET predictions from density altitude, your reference runs, and wind
• See the breakdown behind every number: reference run + air + wind
• Confidence grows the more you log
• 1/8 and 1/4 mile kept separate — never mixed
LOG RUNS FAST
• Snap your timeslip and let TrackR read it for you
• Automatic weather and density altitude at your track
• Capture 60-foot, splits, MPH, reaction time, dial-in, and finish margin
• Win/loss and round-by-round history
KNOW YOUR CONDITIONS
• Live density altitude for your track
• Hourly ET forecast — find the best window to run
• Weather what-if simulator: see how cooler air or a headwind moves your ET
TRACK YOUR CAR
• Full car profile and setup baselines
• Maintenance reminders by runs, race days, calendar, and season
• A setup snapshot saved with every pass
MORE
