AST Multipoint Weld-in Roll Cage BMW E46 Coupé V4

The AST Multipoint Weld-in Roll Cage BMW E46 Coupé V4 is a full roll cage for the BMW E46 with 2-door coupé bodywork. This Multipoint E46 V4 is the heaviest build in the range and adds extra diagonal bars and harness bars to the V3, permanently welded to the bodyshell at 10 points.

The cage is designed and built by AST Roll Cages in Spain, for drivers who want to stiffen their E46 Coupé to the limit and attach their harnesses to the cage.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. Decide on the position of your bucket seats before the harness bar is finally welded in, as its height determines the angle of your shoulder straps. Because AST digitises the bodyshell with laser scanners and designs the cage in 3D, the harness bar also ends up exactly where it belongs.

The V4 is the end point of the range: everything from the V3, supplemented with extra diagonal bars and a harness bar.

Why choose this Multipoint E46 V4 roll cage?

Anyone who uses their E46 Coupé seriously wants both torsional rigidity and a correctly mounted harness. The V4 solves both in a single structure and saves you separate brackets and compromises later on. If you are already building with the future in mind, this is the version you will not need to revisit.

Frequently asked questions

Can I attach my harness to this cage?

Yes, that is what the harness bar is for. The Multipoint E46 V4 has this bar as standard, so the shoulder straps do not need to be attached to the bodyshell.

Is the V4 much heavier than the lower versions?

The stated weight is 71 kg (manufacturer’s figure), the same as the rest of the range.
