Size/Fitting guide

This JP Renault Megane MK2 Half Cage is made for this shell specifically, so the feet and the tube runs are already right.

Made from CDS (cold drawn seamless) tube, the standard material for competition cages and the one most regulations are written around.

Approval and eligibility

This cage is listed as Road & Track. Check that against the regulations for the championship or class you run in before you buy, because eligibility varies by discipline and by year.

If a cage needs signing off for competition, the paperwork usually has to follow the car, so keep the certification with the logbook. Worth understanding before you commit: what a roll cage actually does in a crash.

Bolt-in or weld-in?

Bolt-in cages mount on spreader plates through the floor and sills. No welding, no permanent change to the shell, and they can come out again. That makes them the sensible choice for a road car, a track day car, or anything you might sell on standard.

Weld-in cages are welded straight to the shell. You get a stiffer car and a better load path into the structure, which is why the sharper end of stage rally and circuit racing runs them. The trade is that it is permanent, it wants a proper fabricator, and the interior usually has to come out to do it.

For most people the deciding factor is the regulations. Check what your class requires first, then pick on practicality. If you are between the two, tell us what you compete in and we will point you at the right one.

Fitting the JP Renault Megane MK2 Half Cage

A bolt-in cage mounts on spreader plates through the floor and sills. It can be fitted without welding, and it can come back out, which matters if the car is a road car or a lease-return shell.

Fitment is listed as stripped interior. Plan the interior strip before the cage arrives, it is usually the longer job of the two.

Dry fit the whole cage before anything is permanent. Check door and window clearance, seat position, and that you can still get in and out in a helmet with a harness on.

Pad every tube within helmet reach with FIA-rated padding. In a road car without helmets, a bare tube next to your head is a genuine hazard, so plan the padding at the same time as the cage.

JP Renault Megane MK2 Half Cage questions

Is the JP Renault Megane MK2 Half Cage a direct fit?

It is built for this shell, so the mounting points and tube runs are already correct on a standard car. Previous accident damage or a non-standard interior can still change what is needed.

Can I fit the JP Renault Megane MK2 Half Cage myself?

A competent home mechanic can fit a bolt-in cage. It needs care over the spreader plates and the torque on the mounting bolts, and it is a two-person job to get the main hoop in.

Will it pass scrutineering?

It is listed as Road & Track. Check the current regulations for your class, and keep the certification with the car. If you tell us what you compete in we will confirm before you order.

Does it affect my insurance?

Yes. A cage is a notifiable modification. Tell your insurer before the car goes back on the road, and be specific about the cage type, because some insurers treat bolt-in and weld-in differently.

Do I need harnesses as well?

A cage with a harness bar is designed to mount harnesses properly. If you are fitting harnesses at the same time, see our harnesses, and make sure the mounting angles suit the seat you are running.

How much weight does a cage add?

A rear cage is the lightest option, a full multipoint cage the heaviest, and material choice moves it again. T45 saves weight over CDS for the same strength, which is why it costs more. Weight gain is usually worth it for what the cage does to shell stiffness.

Can I still use the back seats?

Depends on where the backstays land. Check the design listed above, and tell us how you use the car if you need it confirmed.

Is the JP Renault Megane MK2 Half Cage paint finished?

Cages are normally supplied in the manufacturer’s standard finish. If you need a specific powder coat colour, ask us before ordering because it usually adds lead time.

Send us your car details and what you compete in, and we will confirm the JP Renault Megane MK2 Half Cage is the right build for it.

Roll cage specification and fitment guide

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

Type	How it fits	What it means
Bolt-in	Bolts to mounting plates on the floor and sills	Removable. No welding. The usual choice for a road car or a track day car
Weld-in	Welded directly into the shell	Permanent and stiffer. What most competition classes require

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

Configuration	What it is	Typical use
6 point	Six mounting points	Rear cages and lighter installations
Multipoint	Eight points minimum	Full cages. What most championships ask for

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

Material	What it is	Why you would pick it
CDS	Cold drawn seamless steel	The standard. Strongest value, heaviest of the three
T45	Carbon manganese alloy	Higher strength for the weight, so a lighter cage. Costs more
25CrMo4	Chromoly	The lightest for a given strength. Specialist welding, top of the range

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

Design	What it adds
Single fixed diagonal	The simplest rear brace
Cross diagonal and harness bar	Adds a harness mounting point
Multipoint cross diagonal and harness bar	A fuller structure
With door bars	Adds side impact protection, and makes getting in harder

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.
