StemmaPass
How long do your parts last on track?
An hour on circuit does not wear like a hundred kilometres of road. This calculator applies the same factors as the StemmaPass logbook.
Wear over one season
150 %
This component will not last a full season.
18.0 effective track hours, against a reference life of 12 h on track or 40,000 km on road.
Estimated from average service lives. Your driving style, the brand you fit and ambient temperature all change the result — sometimes by a factor of two.
Why track hours matter more than kilometres
Brake fluid takes in one session what road use would inflict over months: repeated heat cycles, accelerated moisture absorption, constant pressure cycling. Reasoning in kilometres makes you miss the interval — which is exactly why StemmaPass has a wear engine.
Track your car’s real wear
This calculator works on averages. The logbook works from your own invoices and your actual sessions, and warns you before the outing.
