AST Weld-in Roll Cage BMW E46 Touring V4 NASCAR door

The AST Weld-in Roll Cage BMW E46 Touring V4 NASCAR Door Bars is a full roll cage for the BMW E46 with 5-door Touring bodywork. On top of the V3 level, this Weld-in E46 Touring V4 NASCAR has an extra diagonal brace and a harness bar, making the rear section noticeably more rigid and giving your harness a fixed mounting point.

The cage is designed and built by AST Roll Cages in Spain, for drivers who are permanently converting their Touring into a drift or track car and deliberately choose a welded-in construction over a removable one.

Key benefits

• NASCAR door bars: instead of the usual single door bar, several curved tubes run through the door. This gives more protection in a side impact and at the same time makes it easier to get in and out.
• Eight welded mounting points: the structure is welded to the bodyshell in eight places, so the forces are spread over a large part of the body.
• Extra diagonal brace and harness bar: exactly what the V4 level adds to the V3 build, providing more torsional rigidity and a fixed anchorage point for the belts.
• E355 steel: the main hoop has a diameter of 45 mm, while the rest of the structure uses 40 mm tube.
• Gussets and reinforcement plates: included in the kit, they spread the load at the points where the cage is attached to the body.
• Custom-made for each car: the foot plates are made of 3 mm steel and designed specifically for this chassis.
• Complete weld-in kit: including bolts, washers and 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. AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that it fits your car exactly. Have the welding-in carried out by an experienced welder, as the eight welded mounting points together determine how well the structure ultimately does its job.

A V4 weld-in cage with NASCAR door bars combines a rigid rear structure with the roomiest entry of the entire range.

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

The V4 is the point at which a weld-in cage feels complete without you having to go straight to the heaviest specification. You get the extra diagonal and the harness bar, and the NASCAR door bars ensure that, despite all that tubing, you can still get behind the wheel comfortably. For a Touring that frequently goes on and off a trailer, that makes a difference every time you head out.

Frequently asked questions

What is the difference from a standard door bar?

On this Weld-in E46 Touring V4 NASCAR, the door is fitted with a set of curved tubes instead of a single straight bar. These absorb a side impact over a larger area and leave space free in the middle, so getting in and out remains easier than with the standard version.

What exactly will I receive?

You receive the unpainted weld-in kit with gussets and reinforcement plates, the bolts, washers and nuts, the documentation, the fitting instructions and a sticker set. The cage arrives untreated, so you can choose the finish yourself.
