Antriebstechnik Schmidt

One-offs · Small series · Motorsport

Precision you can measure.

Antriebstechnik Schmidt machines limited-slip differentials, drive shafts and gear parts for classic Porsche, historic motorsport and the automotive industry – on our own machines in Germany.

We are a gear-cutting workshop: what the factory no longer supplies, what the standard part cannot take, and what has never existed — gets drawn, turned, gear-cut, ground and set up right here.

25 + years of experience in gear cutting and drivetrain work
