Custom Cages Hillman Avenger Historic T45 Roll Cage Kit

This Hillman Avenger Historic T45 Roll Cage Kit is made for this shell specifically, so the feet and the tube runs are already right.

Made from T45 tube, a higher strength alloy steel that gives the same strength as CDS at lower weight.

Hillman Avenger Historic T45 Roll Cage Kit specification

Approval and eligibility

This cage is listed as MSUK Compliant. 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 Hillman Avenger Historic T45 Roll Cage Kit

A weld-in cage is welded directly to the shell. It is stiffer than the equivalent bolt-in and it is what most stage rally and circuit regulations expect at the sharper end.

Fitment is listed as weld in. Trim removal is limited to what the tube runs need.

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.

Roll bar padding is not optional on tubes near the driver or passenger head. Budget for FIA-rated padding when you order the cage, not afterwards.

Hillman Avenger Historic T45 Roll Cage Kit questions

Is the Hillman Avenger Historic T45 Roll Cage Kit 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 Hillman Avenger Historic T45 Roll Cage Kit myself?

Only if you can weld to a proper standard. A weld-in cage is structural, and a bad weld is worse than no cage. Most people have these fitted by a motorsport fabricator.

Will it pass scrutineering?

It is listed as MSUK Compliant. 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 Hillman Avenger Historic T45 Roll Cage Kit 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.

If you need the Hillman Avenger Historic T45 Roll Cage Kit confirmed against your shell, sunroof, or the regulations you run under, send us the details and we will check before you order.
