AST Weld-in Roll Cage BMW E46 Compact V1

The AST Weld-in Roll Cage BMW E46 Compact V1 is a full roll cage for the BMW E46 with 3-door Compact bodywork. This Weld-in E46 Compact V1 consists of the main hoop with backstays and is permanently welded to the bodyshell at 8 points.

The cage is designed and built by AST Roll Cages in Spain, for drivers who want to start with a clean base frame and build up their Compact step by step.

Key benefits

• Permanent connection: eight welded mounting points join the cage directly to the bodyshell, with no play.
• E355 steel: 45 mm main hoop and 40 mm for the remaining tubes.
• Custom-scanned: the bodyshell is digitised so that every tube fits neatly.
• Lightweight base frame: 71 kg for a complete structure with backstays.
• Plenty of interior space: getting in and out stays easy because there are no door bars yet.
• Complete weld-in kit: including gussets and reinforcement plates.
• Supplied unpainted: you choose the colour and finish yourself.

The lightest step towards a welded-in cage in the E46 Compact: main hoop plus backstays, 71 kg.

Why choose this Weld-in E46 Compact V1 roll cage?

A welded cage is more rigid than a bolt-in cage, because the forces are absorbed directly by the bodyshell. AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that it fits your car exactly. If you later want more tubes around the driver, V2 to V5 are the logical next steps.

Frequently asked questions

What is the difference between weld-in and multipoint weld-in?

The Weld-in E46 Compact V1 is attached to the bodyshell at 8 welded mounting points, whereas a multipoint weld-in cage uses 10 and therefore spreads the forces over more points.
