We work on Porsche, and little else.
RS Motorwerks provides independent Porsche service and repair in Norcross, Georgia, for owners throughout Atlanta and the Southeast. We work on all Porsche models from 1948 to the present, with particular expertise in classic air-cooled Porsches.
Our services include Porsche maintenance, diagnostics, engine rebuilding, transmission repair and rebuilding, and pre-purchase inspections. From routine service to complex mechanical work, we start with a careful assessment and explain what your Porsche needs, what can wait, and why. Engine and transmission rebuilding is handled in-house, with attention to the details that matter to your car.
Whether you’re maintaining a modern Porsche, caring for an air-cooled classic, or considering a used Porsche purchase, our approach is the same: clear advice, careful workmanship, and repairs that respect your car’s originality.

How we got here.
The shop opens.
RS Motorwerks starts out as an independent, family-run specialist in the Atlanta area, built on doing careful, honest work the dealership route often couldn’t.
Focus shifts to Porsche.
As more owners bring us their Porsche, we lean into it, rebranding as RS Motorwerks and building the model-specific knowledge that classic and air-cooled cars really need.
Porsche specialists for the Southeast.
Owners travel to us from across Atlanta, Tennessee, South Carolina and Florida for maintenance, diagnostics and full engine and transmission rebuilds, all handled in-house by the same team, start to finish.
The same approach on every car.
Diagnosis first
We confirm what’s actually wrong before any parts get ordered or anything comes apart.
Repair or rebuild
We’d rather repair or rebuild than replace, protecting both your budget and the car’s originality.
In-house, start to finish
One team handles the work from first inspection to final road test. Nothing gets sent out.
No upsell
We tell you what needs doing now, what can wait, and why. No surprises on the bill.
The people behind the work
Independently-owned, hands-on.
RS Motorwerks is an independently-owned and operated, with decades of combined experience under one roof. The people who diagnose your car are the same ones who work on it.
