AST Multipoint Weld-in Roll Cage BMW E46 Sedan V5 NASCAR door

The AST Multipoint Weld-in Roll Cage BMW E46 Saloon V5 NASCAR Door Bars is a full roll cage for the BMW E46 with 4-door saloon bodywork. This Multipoint E46 Saloon V5 NASCAR is the most complete cage AST designs for this car: the full set of bars on ten welded mounting points, with doors filled with curved tubes in NASCAR style instead of the standard door bar.

The cage is designed and built by AST Roll Cages in Spain, for teams and drivers who are building their E46 saloon into a genuine competition car and do not want to compromise on any part of the safety structure.

Key benefits

• Full set of bars: every element AST designs for this body style is included, from the main hoop and braces to the diagonals and harness bar.
• Ten welded mounting points: the highest number of mounting points in this range, so the load is spread as widely as possible across the bodyshell.
• NASCAR door bars: several curved tubes per door spread a side impact over a larger area than a single bar.
• Practical entry: despite the number of tubes, the curved shape keeps the door opening accessible.
• Highest rigidity: thanks to the full bar layout and the ten mounting points, the cage acts as a closed frame around the cockpit.
• Custom scanned: AST digitises the E46 saloon with laser scanners and develops the cage in 3D.
• Complete package: weld-in kit with gussets, reinforcement plates and all mounting hardware.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. This is the most labour-intensive level to fit: the car must be fully stripped and all ten welded mounting points must be clean and easily accessible before you start. AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that it fits your car exactly.

Everything AST designs for the E46 saloon, on ten welded mounting points and with NASCAR door bars: the range for this car goes no further.

Why choose this Multipoint E46 Saloon V5 NASCAR roll cage?

This is the cage for a car that will never go back on the road. You get the full bar layout, the harness bar, all the diagonals and the most substantial door version, anchored at ten points in the bodyshell. If you do not want to have to add to it later, start here straight away. The cage is supplied unpainted, so you can finish it in your project’s colour scheme after welding it in.

Frequently asked questions

Is this the most comprehensive version available?

Within this range, yes. This Multipoint E46 Saloon V5 NASCAR combines the full set of bars with the highest number of welded mounting points and the NASCAR door version, whereas lighter versions leave out bars step by step.

What do NASCAR door bars mean in practice?

The door contains several curved tubes instead of the standard straight door bar. As a result, a side impact is absorbed over a larger area and you are left with more room to get in and out of the car.

What is included?

An unpainted weld-in kit with gussets, reinforcement plates, bolts, washers and nuts, documentation, fitting instructions and a sticker set. The cage is intended for track and competition use; always check the regulations of your own organiser.
