If you think of it, we can build it, we can fab it.

One-off metal fabrication for drift, JDM and time attack cars. Cages, exhaust, panel work and everything the catalogue doesn't sell. Cut, formed and welded in the greater Sacramento area.

Built for cars that get used.

Drift cars and track cars are the specialty. That's what rolls through the door most weeks and that's what the shop is set up for. Past that, we'll take on any car and any project, from a full build down to the one bracket nobody makes.

Everything is measured, tacked and fitted in the car. Nothing gets ordered off a shelf and forced to line up. Bring the shell, the parts and the idea.

  • DriftAngle kits, cages, radiator and cooling relocations, bash bars and the repairs that come after contact. This is what the shop does most.
  • Everything elseJDM builds, time attack cars and any track project, plus swap mounts, custom piping and the one-off brackets nobody sells. Any make, any class.

What the shop builds

Fabrication in steel, stainless and aluminium. TIG and MIG, mandrel bends, formed and dimple-died sheet. Below is the everyday list. The one-offs are the reason to call.

Custom roll cages

Weld-in multi-point cages built around your shell and your seating position. Notched and fitted in the car, tied into the strut towers and rockers, with door bars, halos and harness mounts placed where they protect the driver instead of where they're easy to reach.

  • Multi-point
  • Door bars
  • Harness mounts
  • Cage tie-ins

Exhaust

Mandrel-bent stainless, TIG welded and back-purged. Merge collectors, V-band joints so the car comes apart in the paddock, and hangers routed to clear the cage, the tunnel and the ground.

  • Stainless
  • V-bands
  • Merges
  • Full systems

Firewalls

Sheet metal firewalls, transmission tunnels and rear bulkheads formed to the chassis, riveted and sealed. Made to keep heat, fuel and fumes out of the cabin and to pass tech without an argument.

  • Sealed cabin
  • Tunnels
  • Dimple-died panels

Trunk enclosures

Boxed rear compartments for fuel cells, pumps, surge tanks and coolers. Sealed away from the driver, panelled in aluminium and still serviceable with a rivet gun between sessions.

  • Fuel cell boxes
  • Pump mounting
  • Aluminium panels

Battery housings

Relocated trays and enclosures built into the chassis or the rear structure, braced against the loads a track car actually sees, with the terminals covered and the cut-off where a marshal can find it.

  • Relocations
  • Braced mounts
  • Cut-off wiring
