AST Bolt-in Roll Cage BMW E46 Compact V3

The AST Bolt-in Roll Cage BMW E46 Compact V3 is a full roll cage for the BMW E46 with 3-door Compact bodywork. This Bolt-in E46 Compact V3 retains all the reinforcements of the V2 and adds door bars, so the driver is also shielded from the side.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. Bear in mind that the door bars take up space in the door opening, so check in advance how you will get in and out with your seat and harness system.

With door bars added, the bolt-in cage truly becomes a shield around the driver.

Why choose this Bolt-in E46 Compact V3 roll cage?

AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that the door bars run tightly along the sill area without clashing with your seating position. Side impacts are a real risk in drifting; this version tackles that head-on. You also keep the removable construction of the bolt-in range.

Frequently asked questions

What is new in the V3?

The Bolt-in E46 Compact V3 adds door bars to the reinforced structure of the V2. That is the main difference; the mounting at six bolting points stays the same.

Can I take the cage out again later?

Yes. The structure is divided into sections via connecting sleeves, so the cage comes out of the car again in pieces. Only the six welded foot plates remain in place.
