We don't just service Porsches

We manufacture for them.

We build our own hardware in-house. We design, fabricate, and powder-coat it ourselves — chromoly bolt-in roll bars, seat and sub-belt mounts, transmission mounts, and the diagnostic tooling we use every day. Engineered for a specific chassis, finished to a standard we'd put in our own cars, and 100% bolt-in: no cutting, no welding, fully reversible.

  • 4130 chromoly bolt-in roll bars — 981 · 987 · 996 · 997 · 991 · 992
  • Seat adapters, side & sub-belt mounts for proper harness geometry
  • Transmission mounts & precision chassis hardware, engineered to fit
  • Designed, built, and proven in Bellevue — not drop-shipped

Proven where it counts

We don't sell theory.
We build what holds up.

Our parts and our builds get sorted on lapping days, not in a catalog — because the only proof that counts happens between corners. From Thunderhill to The Ridge, if it carries the Cantrell name, it's been tested where it has to hold together.

"We've spent two decades earning the right to put our name on a part. Every roll bar, every build, every lap — it carries the Cantrell name because we'd trust it under our own car."
