AST Bolt-in Roll Cage BMW E46 Touring V4

The AST Bolt-in Roll Cage BMW E46 Touring V4 is a full roll cage for the BMW E46 with 5-door Touring bodywork. This Bolt-in E46 Touring V4 builds on version V3 and adds an extra diagonal brace and a harness bar, so that the structure forms a closed system and the harnesses get a fixed anchorage point.

The cage is designed and built by AST Roll Cages in Spain, for drivers who use their Touring as a genuine competition car and want the most rigid bolt-in level in this range.

Key benefits

• Harness bar gives the shoulder straps of a racing harness a fixed and correctly positioned anchorage point.
• Extra diagonal brace in the main hoop keeps the cage in shape under heavy lateral loads.
• Door bars in both doors for protection in a side impact.
• Front reinforcement bars running to the bulkhead firmly tie the front section to the main structure.
• Six welded foot plates in 3 mm steel, onto which the cage is bolted.
• E355 steel with a 45 mm main hoop and the remaining tubes in 40 mm.
• Supplied complete with connecting sleeves, reinforcement plates, mounting hardware, instructions and a sticker set.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. The six foot plates are welded to the bodyshell, and only then is the cage bolted onto them. Determine the position of the harness bar together with the seat and the harnesses, as these three need to be matched to one another.

Version V4 combines door bars with an extra diagonal brace and a harness bar, the most rigid level within this bolt-in range.

Why choose this Bolt-in 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 diagonal brace and the harness bar sit exactly where they do the most work, without you losing any seating space. If you use your Touring seriously on the track or for drifting, this is where you get the most rigidity and the greatest harness comfort.
