Roll cages are not sized to you. Every one we sell is made for a specific car, so the first filter is your make, model and year. After that you are choosing four things: bolt-in or weld-in, how many mounting points, which material, and which approval you need.
Start with the regulations, not the cageWhich cage you can use is decided by your championship or club, not by preference. A cage that is wrong for your class is an expensive thing to find out about at scrutineering. Check the regulations first, then filter.
Bolt-in or weld-in
Bolt-in is the practical choice for a car that is still road registered, or one you might want to return to standard. Weld-in is stiffer, because the cage becomes part of the shell rather than something bolted to it, and it is what most competition classes require. It also means cutting trim and carpet and it is not coming out again.
Mounting points
A rear cage protects the driver from behind and gives you somewhere to mount harnesses. A full multipoint cage adds the front hoop and the roof. If you are fitting harnesses and nothing else, a rear cage with a harness bar may be all you need, and it is far less intrusive to live with.
Material
For most road and track day cars, CDS is the right answer and the price difference is better spent elsewhere. T45 and chromoly earn their money in competition where the weight saving is worth paying for, and where the class allows them. Check your regulations, because not every class accepts every material.
Design
Door bars are the trade-off worth thinking about. They are a real gain in side impact protection and they make climbing in and out considerably harder, which matters more than people expect in a car you use often. If the car is road driven, try getting in over a door bar before you commit.
Approvals, and what our labels mean
These are the exact terms you will see on our products, and they are not interchangeable.
AFIA Approved, and FIA / Motorsport UK HomologatedCarries an FIA homologation. What international and top-level national competition requires.
BMotorsport UK Nationally HomologatedHomologated for UK national competition.
CMotorsport UK Homologated (installation approval required)Homologated, but the fitted installation itself has to be approved as well. Factor that into your timescale.
DMSUK CompliantBuilt to the Motorsport UK specification.
ENot for competition useTrack day and road cages. Not accepted for competition.
Fitting and finish
Our cages are manufactured in the United Kingdom and supplied in bare metal, with powder coating available as an option. Bare metal is the standard because most people want to paint or coat it to match the car, and because a coated cage still has to be prepared where it welds.
Get a weld-in cage fitted properlyA weld-in cage is a structural part of the car. It wants fitting by someone who does it regularly, and where the approval says installation approval is required, it has to be signed off as well. Bolt-in cages are within reach of a competent home fit, but read the instructions before you start rather than after.
Before you order
Check the exact model and year against the product. Our cages are listed to specific variants, and a Focus Mk3 cage is not a Mk2 cage. Some are listed as rear cage only, which is easy to miss when the title otherwise matches. If your car has a sunroof, a different roof pressing or a factory option that changes the shell, tell us before you order.
Tell us the car and the championshipMake, model, year and exactly what you are competing in, or whether it is track days only. The regulations narrow the choice more than anything else, and we would rather work through it with you than have a cage come back. Call 0115 989 3488 or email Sales@GSMPerformance.co.uk.
All specifications read from our own product data across the roll cage categories, checked 2 August 2026. Approval wording is quoted as it appears on our products. Always confirm against your current championship regulations, which change.
