Custom Cages weld-in kit
Custom Cages is British roll protection's institution: the weld-in kits and FIA-homologated cages — T45 steel the signature — that turn shells into race cars, with the paperwork motorsport's scrutineers actually recognise.
History
Custom Cages built its UK operation into Europe's volume roll-cage authority: weld-in kits (pre-bent, notched tube sets per chassis, fitted by the builder's welder), full FIA-homologated cages carrying certification through national ASN or FIA registration, and the material ladder that made the firm's name — CDS as the honest baseline, T45 carbon-manganese steel as the premium signature offering strength at reduced weight, the specification serious rally and race builds default to.
The institutional role matters as much as the tube: cage certification is motorsport's least forgiving paperwork, and Custom Cages' homologation library (per-model certified designs across the rally and race fleet) plus scrutineering recognition across European ASNs makes the brand's documentation part of the product — a certified cage travels with papers or it's just pipework.
For buyers the cage market is really a shell market: cages sell inside the cars they were welded into, kit purchases are new-build decisions, and the diligence is documentary — certification papers matching the cage's plate, installation quality (weld inspection), and damage history, because a crashed cage is scrap by rule and by sense.
Palmarès
Protecting British and European rally and race champions across three decades — the cage record: rollovers walked away from, scrutineering passed on paper the first time, and the shells that raced because the certification existed.
What to check before you buy
Papers make the cage: a certified Custom Cages installation carries documentation (homologation certificate, cage plate matching) — verify the paper trail against the physical plate, because certification transfers with evidence, not with anecdote. Inspect weld quality throughout (installer skill decides a weld-in kit's actual strength), corrosion at foot-plates and gussets, and any impact evidence — damaged cages are condemned, not repaired, in every serious rulebook. Material identity (T45 versus CDS) affects value and weight honestly. Kit purchases for new builds: confirm the current-rules design for your exact shell and series before ordering.
Did you know
- T45's aerospace lineage — carbon-manganese steel from British aircraft tradition — made it cage-building's premium word: strength without the weight penalty.
- A cage's certification plate is its passport: scrutineers read the numbers before they admire the welding, and paperless cages die at pre-event checks.
- Weld-in kits democratised proper cages: pre-bent, notched tube sets meant a competent local welder could install certification-grade protection.
