AST Multipoint Weld-in Roll Cage BMW E46 Sedan V2

The AST Multipoint Weld-in Roll Cage BMW E46 Saloon V2 is a full roll cage for the BMW E46 with 4-door saloon bodywork. This Multipoint E46 Saloon V2 carries over the ten welded mounting points and the main hoop with braces from the V1 and adds front reinforcement bars running to the bulkhead, so that the bulkhead also helps carry the loads.

The cage is designed and built by AST Roll Cages in Spain, for drivers who, in addition to safety, are looking for noticeably more torsional rigidity at the front of their E46 Saloon.

Key benefits

• Front reinforcement bars extend to the bulkhead and tie the cage to the front section of the bodyshell.
• Less flex at turn-in, so the front suspension does what you ask of it instead of the bodyshell flexing along with it.
• Ten welded mounting points on the bodyshell, two more than on a standard weld-in cage.
• E355 steel with a 45 mm main hoop and 40 mm for the remaining tubes.
• Foot plates in 3 mm steel, custom-designed for each car for correct load transfer.
• Complete weld-in kit with gussets, reinforcement plates and all bolts, washers and nuts.
• Supplied unpainted, ready to be finished in your own colour after welding.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that it fits your car exactly. Bear in mind that the front bars run to the bulkhead, so the dashboard and its associated trim must be removed or modified.

With bars running right up to the bulkhead, the V2 integrates the front of the E46 Saloon into the structure of the cage.

Why choose this Multipoint E46 Saloon V2 roll cage?

The difference between V1 and V2 lies entirely at the front. This Multipoint E46 Saloon V2 connects the main structure to the bulkhead, so the nose of the car moves less independently of the rest. On a twisty circuit, you feel this in sharper turn-in and a more stable line.

Frequently asked questions

What is the difference from the V1?

Does the interior need to be stripped?

To weld the cage in, the dashboard, trim and door cards will have to be at least partly removed. Expect to modify the interior parts around the tubes and foot plates.

The cage is built for track and competition use. Check with your own federation or sporting organisation which safety requirements apply to your car, class and championship.
