The Space-Frame Chassis

Engineered To Define Performance

A chassis must do more than sit beneath the body — it must define performance. Our hand-built space frame is modeled on the same principles found in high-performance race cars: triangulated members so loads travel through struts in pure tension or compression, rather than bending or torsion.

We reference the suspension hard-points of the Chevrolet C5 Corvette, preserving its proven geometry — particularly the zero scrub radius at the front — to optimize response, steering feel, and stability under load. Unlike the factory C5, our design omits anti-dive geometry to keep handling consistent under braking and corner loading with the mid-engine layout.

Our Build Process

Model. Test. Weld.

  • Define suspension hard-points, engine mounts and occupant space early, so the geometry supports both performance and ergonomics.
  • Apply virtual torsional, bending and impact loads in the digital model, then iterate member sizing and bracing until targets are met.
  • Only then hand-fabricate the frame, weld it with precision, and match it to the body — every tube and fixture aligned to the virtual model.

Racing structural theory, artisan build quality. This is structure you can feel, built with purpose.
