AST Bolt-in Roll Cage BMW E30 Sedan AWD V2

The AST Bolt-in Roll Cage BMW E30 Saloon AWD V2 is a full roll cage for the all-wheel-drive BMW 3 Series (E30), the 325iX, with 4-door saloon bodywork. This Bolt-in E30 Saloon AWD V2 supplements the basic structure with two front reinforcement bars running to the bulkhead and is designed specifically for the all-wheel-drive E30 (325iX).

The cage is designed and built by AST Roll Cages in Spain, for 325iX drivers looking for a gain in torsional rigidity, as the front end takes extra punishment with all-wheel drive.

Key benefits

• Front reinforcement bars: two bars run through to the bulkhead and bring the front end of the 325iX into the structure.
• Specifically for all-wheel drive: the cage is designed around the different transmission tunnel and floor of the all-wheel-drive E30.
• FIA homologation: AST states homologation number 5348, valid for the BMW 325iX according to FIA Appendix J.
• Six bolting points: bolted onto six foot plates in 3 mm steel that are welded to the bodyshell.
• E355 tubes: 45 mm main hoop, 40 mm for the rest of the structure.
• Supplied in removable sections: connecting sleeves split the cage into sections that fit through the door opening.
• Complete and unpainted: includes reinforcement plates, 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. The front bars run along the dashboard to the bulkhead, so fit the cage before the interior goes back in. The six foot plates are welded to the bodyshell and only then is the cage bolted onto them, so welding is part of the fitting process.

On a 325iX, the front end works hardest, and that is exactly where the V2 steps in with two bars to the bulkhead.

Why choose this Bolt-in E30 Saloon AWD V2 roll cage?

The 325iX sends power to the front axle, which puts more load on the strut towers and bulkhead than on a regular E30. Extending the cage to the bulkhead makes that area part of the safety structure. AST digitises the bodyshell with laser scanners and designs the cage in 3D, so the bars run along the dashboard without making the car impractical to drive.

Frequently asked questions

Which E30 is this cage intended for?

The Bolt-in E30 Saloon AWD V2 is intended exclusively for the all-wheel-drive E30 (325iX). It does not fit a rear-wheel-drive E30 saloon; AST supplies a separate RWD version for that car.

What does the V2 add compared with the V1?

The V1 stops at the main hoop with braces. On top of that, the V2 has two front reinforcement bars that run through to the bulkhead and bring the front of the car into the overall rigidity.
