Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. Expect a fully stripped interior: with this many tubes, you need plenty of room to work, and an experienced welder is no luxury. AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that it fits your car exactly.

The V5 is the end point of the weld-in range for the E46 saloon: every bar AST designs for this body style is included.

Why choose this Weld-in E46 Saloon V5 roll cage?

Having bars welded in afterwards means paying twice: once for the steel and once for stripping the car again. If you go for the full package straight away, the structure is right first time and you have the most rigid foundation available for this body style. For competition use, it is also the version least likely to run up against the limits of the regulations.
