Antriebstechnik Schmidt GmbH, represented by its Managing Director Horst
Schmidt, is a small workshop in Ottrau-Weißenborn, Hesse, Germany. We design, machine and sell drivetrain and
mechanical-engineering parts — with more than 25 years of experience in
gear cutting. In May 2021, after 25 years at the previous location, the
workshop moved to its current site with 800 m² of production and stock
space.
Many of our parts are distributed through specialist Porsche dealers and
parts suppliers; just as many go directly to motorsport customers racing
in a wide range of historic series. The standard is the same either way:
one-off production that satisfies the highest demands — measured,
documented, ready to install.
How we work
You are not talking to a sales department here — you are talking to the
man at the machine. Inquiry, advice, quote, machining and invoice come
from one person, from the first call to a detailed, transparent bill.
Whatever cannot be settled by phone or online is settled at the part:
visits are welcome any time by appointment, even if a production shop is
not a showroom.
