Component life tracking for race teams and private owners

Every part has a life.
Know what’s left.

log.racing keeps component life, session history and replacement records in one place, so you always know what has been used, what is due next and what needs attention before the car goes out again.

Log one session and every fitted component updates automatically — in hours, starts, kilometres or miles. It works the same whether you run a six-car programme or one car out of your own garage.

Already have a lifing spreadsheet? Send it to us and we’ll load it for you.

Component lifing built on the principle aviation has used for decades.

Aviation has tracked life-limited parts this way for decades, because a spreadsheet that only one person understands is not a maintenance record. The terminology maps directly across.

A new season resets the report. It does not reset the gearbox.

Four numbers, and you know where the car is.

Everything on the opening screen answers one question: what needs doing before this car runs again?

29.00
Total hours

Hours carried over from before the app, plus every session since. Intervals are measured against this, not against the season.

22
Due soon

Inside the last 15 per cent of their interval. Time to order the part, not to panic.

503
km left

Each part is counted in the measure it is rated in. Brakes in kilometres, the engine in hours — all on the same car.

    Tyres are part of the car’s history too.

    Track each set by tyre number, compound, size and fitting position. Record when it went on the car, how many sessions or kilometres it has completed, and when it was removed.

    A simple record of what each set has done, what is fitted now and what is still available to use.

    Each corner carries its own reading, so a set that gets rotated keeps its history.

    Every change has a name attached.

    Give each person their own PIN, role and car access. Every session and replacement stays attached to the person who recorded it.

    Car not in the library yet? We build the template from the manufacturer’s documentation at no charge, and it stays in the library for everyone who runs one afterwards.

    Send us your lifing spreadsheet.

    We’ll turn your existing component list, intervals and lifing data into a working log.racing account and send you the link — usually within the same week.
