PROJECT E21

Refining the original 3 Series one part at a time.

A place to share the restoration, modifications, and adventures of a 1981 BMW 320i. Real projects, real progress, and everything learned along the way.

MACHINED TOLERANCES

Bespoke components built to spec.

Every bracket, spacer, and custom weld is engineered for absolute structural integrity and period-correct aesthetics.

Analog engineering.

We design and fabricate high-performance components that preserve the raw, analog driving feel of the classic E21 chassis. No compromises, no mass production.

High-tolerance machining.

Period-correct design.

We work with raw billet aluminum and high-grade steel, machining every component to exact tolerances. Our parts integrate precisely with the vintage chassis while offering modern durability.

Every design decision respects the original 1970s aesthetic. We enhance mechanical capability without disrupting the classic proportions and clean lines of your vintage BMW.
