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 welding the cage in, because the harness bar has to match the height of your shoulders in the bucket seat.

The extra diagonal and the harness bar turn the V4 into a cage that is ready for a harness and hard track work.

Why choose this Weld-in E46 Touring V4 roll cage?

A harness is only safe if the shoulder straps are anchored to a solid bar at the right height, and that is exactly what the V4 provides. The extra diagonal also keeps the structure square, so the cage does not flex under load. AST digitises the bodyshell with laser scanners and designs the cage in 3D. If you compete, check the regulations of your own organiser beforehand.

Frequently asked questions

Can I attach a harness to this cage?

Yes. The Weld-in E46 Touring V4 has a dedicated harness bar behind the seats, intended as a mounting point for the shoulder straps of a multi-point harness.

How reliable is the fit on an E46 Touring?

AST digitises the bodyshell of the 5-door Touring with laser scanners and then draws up the cage in 3D. As a result, the foot plates and tubes end up in exactly the right place; they are supplied together with the gussets and the mounting hardware.

What is the delivery time?

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