The Audi MK1 TT – Bolt In Half Cage is cut and bent for this model, which is what keeps fitting time down and the fit tight.
Made from CDS (cold drawn seamless) tube, the standard material for competition cages and the one most regulations are written around.

Approval and eligibility
Check the regulations for your championship or class before ordering. Eligibility varies by discipline and changes year to 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 Audi MK1 TT – Bolt In Half Cage
Bolt-in means it goes in on mounting plates rather than being welded to the shell. Easier to fit at home, and reversible if the car changes hands.
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.
Audi MK1 TT – Bolt In Half Cage questions
Is the Audi MK1 TT – Bolt In 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 Audi MK1 TT – Bolt In 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?
Check the current regulations for your class before ordering. Tell us what you compete in and we will confirm suitability.
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 Audi MK1 TT – Bolt In 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 Audi MK1 TT – Bolt In Half Cage is the right build for it.
