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.

Verschleiß in einer Saison

150 %

Dieses Bauteil hält keine ganze Saison durch.

18.0 effektive Streckenstunden, gegenüber einer Referenzlebensdauer von 12 h auf der Strecke oder 40,000 km auf der Straße.

Schätzung auf Basis durchschnittlicher Lebensdauern. Fahrstil, Fabrikat und Außentemperatur verändern das Ergebnis — mitunter um das Doppelte.

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.
