Custom roll cages · Minnesota

Scanned. Designed. Welded to
your car.

Your shell is 3D scanned first, and the cage is routed against that scan before a tube is cut. What gets welded in was drawn for your chassis, not adapted from somebody else's.

Process

Why it fits

No two shells are identical, even the same model: seams, pillars and old repairs move things. So the cage starts from a scan of your car.

  1. Scanned cup car shell with its cage modelled in red
    01

    Scan

    The stripped shell is 3D scanned, pillars, floor and roof rails included, before any tube is bent.

  2. Porsche shell scan with a full cage designed against it
    02

    Design

    The cage is routed in CAD against that scan: tie-in points, door bars, seat and helmet clearance, in DOM or chromoly to suit how the car is used.

  3. Finished cage welded into an FR-S
    03

    Build

    Tubes are bent and welded to the model, so the cage lands where it was drawn: tight to the body, clean joints, built to your class rules where they apply.

About

Artsem Vechar

Artsem is an automotive fabricator, welder and builder: roll cages, chassis work, performance modifications and one-off parts. His rule is that every cut, bend and weld should serve a purpose, and look right doing it.

Scanning and 3D design are how he holds himself to that. Fitment is settled on the model, so the shop time goes into building it well.

Pricing

What a cage costs

The numbers up front, so you know where your build lands before you ask.

Shop rate $125 per hour
Cage, MIG welded $6,000–8,000 typical
Cage, TIG welded $10,000–12,000 typical

TIG takes longer per joint, which is the difference between the two. Where your cage falls in its range depends on the chassis and the design.
