AST Multipoint Weld-in Roll Cage BMW E46 Sedan V5

The AST Multipoint Weld-in Roll Cage BMW E46 Saloon V5 is a full roll cage for the BMW E46 with 4-door saloon bodywork. This Multipoint E46 Saloon V5 is the most comprehensive specification in the multipoint range and comes with the complete set of bars, from the bulkhead at the front to the rear anchorage.

The cage is designed and built by AST Roll Cages in Spain, for drivers who get the most out of the bodyshell of their E46 saloon and do not want to weld in extra bars later.

Key benefits

• Complete set of bars, the highest specification AST supplies for this multipoint family.
• Maximum torsional rigidity, because the front section, roof, sills and rear are all tied into a single structure.
• Harness bar and diagonal bars from V4 are retained and supplemented by the remaining reinforcements.
• Door bars on both sides for side protection of both driver and passenger.
• Ten welded mounting points on the bodyshell, spreading the load over a wide area.
• E355 steel with a 45 mm main hoop and 40 mm for the remaining tubes.
• 3 mm steel foot plates, designed and manufactured specifically for the E46 saloon.

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. Because of the number of tubes, this is the most involved version to fit; expect a fully stripped interior and an experienced welder.

V5 leaves nothing out: every bar AST designs for the E46 saloon is included in this kit.

Why choose this Multipoint E46 Saloon V5 roll cage?

Welding extra bars into a finished car later on usually takes more time than doing it right in one go. This Multipoint E46 Saloon V5 gives you the complete structure straight away, with ten welded mounting points and custom-designed foot plates. For a car that is driven hard and often, that is the safest and, in the long run, the cheapest route.
