AST Bolt-in Roll Cage BMW E34 Touring V4

The AST Bolt-in Roll Cage BMW E34 Touring V4 is a full roll cage for the BMW 5 Series E34 with 5-door Touring bodywork. This Bolt-in E34 Touring V4 builds on the V3 with an extra diagonal brace and a harness bar, making it the highest specification in the bolt-in range.

The cage is designed and built by AST Roll Cages in Spain, for drivers who are building their E34 Touring into a fully fledged competition car and want to mount the harness system on the cage.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. Settle on your final seat position before you start, as the harness bar needs to sit at the right height behind your shoulders. The six foot plates are welded to the bodyshell, and that work should be left to a specialist fitter.

The V4 is the most complete bolt-in cage for the E34 Touring: diagonal brace, harness bar and door bars in a single structure.

Why choose this Bolt-in E34 Touring V4 roll cage?

If you use a racing harness, you want the shoulder straps anchored to the cage rather than to the bodyshell. The V4 makes that possible with a harness bar and also reinforces the main structure with an extra diagonal brace. AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that all those bars fall into place in the Touring without any improvisation.

Frequently asked questions

What is the harness bar for?

The harness bar on the Bolt-in E34 Touring V4 is the mounting point for the shoulder straps of your racing harness. As a result, those straps run to the cage instead of to the bodyshell.

Can I take the cage out of the car later?

The cage is supplied in sections and joined by connecting sleeves, so it can be removed. The six foot plates, however, remain welded to the bodyshell.

What is the delivery time?

The standard delivery time for this roll cage is 15 to 35 working days.
