AST Multipoint Weld-in Roll Cage BMW E46 Touring V4

The AST Multipoint Weld-in Roll Cage BMW E46 Touring V4 is a full roll cage for the BMW E46 with five-door Touring bodywork. This Multipoint E46 Touring V4 builds on the V3 with an extra diagonal bar and a harness bar, and is welded to the bodyshell at ten points.

The cage is designed and built by AST Roll Cages in Spain, for drivers who do serious competition work and want to attach their harnesses to the cage instead of to the original mounting points.

Key benefits

• Extra diagonal bar keeps the main hoop square under load, so it cannot distort into a parallelogram.
• Harness bar gives your four-point or six-point harness a fixed mounting point at the right height.
• Door bars and front reinforcement bars from the V3 and V2 are fully included.
• Ten welded mounting points on the bodyshell, more than on a standard weld-in cage.
• E355 steel, 45 mm main hoop and 40 mm for the other tubes.
• Gussets and reinforcement plates spread the load across the body panels.
• Unpainted weld-in kit with bolts, washers, nuts, documentation, fitting instructions and a sticker set.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. Settle on the final seat position before welding, because the height of the harness bar depends on the driver’s shoulder height and cannot be corrected afterwards.

The V4 adds the two bars that are most useful in the car: a diagonal that keeps the hoop square and a harness bar for your belts.

Why choose this Multipoint E46 Touring V4 roll cage?

AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that it fits your car exactly. As a result, the harness bar and the diagonal sit in precisely defined positions, not somewhere the welder has to improvise on the spot. For competition use, always check the regulations of your own organiser yourself.

Frequently asked questions

What is the harness bar for?

This bar is where you attach the shoulder straps of your harness. That way the straps run at the correct angle and are not anchored to the car’s original mounting points.

What is the difference from the V3?

The Multipoint E46 Touring V4 has the same door bars and front bars as the V3, but adds an extra diagonal bar and a harness bar. This makes the structure more rigid and better suited to competition use.

What is the delivery time?

The standard delivery time for this roll cage is 15 to 35 working days.
