AST Multipoint Weld-in Roll Cage BMW E21 Coupé V5 NASCAR door

The AST Multipoint Weld-in Roll Cage BMW E21 Coupé V5 NASCAR Door Bars is a full roll cage for the BMW 3 Series E21 with 2-door coupé bodywork. This Multipoint E21 Coupé V5 NASCAR is the highest specification, with the complete set of bars, ten welded mounting points on the bodyshell and several curved tubes in both doors instead of the standard door bar.

The cage is designed and built by AST Roll Cages in Spain, for drivers who are building up their E21 without compromise and don’t want to discover later that a bar is missing.

Key benefits

• Complete set of bars: the highest specification in the range, with no need to add anything later.
• NASCAR door bars: several curved tubes in the door, for greater side protection and more room when getting in than with a straight door bar.
• Ten welded mounting points: permanently welded to the bodyshell, the most rigid connection available for this model.
• Structural benefit: on a light classic like the E21, a full cage makes a noticeable contribution to how settled the car feels on track.
• E355 steel: main hoop with a diameter of 45 mm, the rest of the structure 40 mm.
• 71 kg weld-in kit: despite the complete set of bars, the kit remains light, according to the manufacturer’s figure.
• Supplied complete: gussets, 3 mm steel reinforcement plates, mounting hardware, 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. Expect the longest build time of the entire range: the complete interior and both door cards have to come out, and the cage is welded to the bodyshell at ten points. That choice is final, so decide on your seat, harnesses and steering wheel position beforehand. AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that it fits your car exactly.

The complete set of bars plus NASCAR door bars: the pinnacle of the AST Roll Cages E21 range.

Why choose the Multipoint E21 Coupé V5 NASCAR?

Extending a cage later means welding again in a car that has already been built up, and that is more expensive and messier than getting it right in one go. V5 gives you everything straight away: the complete set of bars, the NASCAR door bars and ten welded mounting points. For an E21 that will spend the rest of its life as a competition car, that is the most logical choice.

Frequently asked questions

How does V5 differ from V4?

V5 has the complete set of bars and is therefore the highest specification in the range; V4 has the extra diagonal brace and harness bar, but not yet all the bars. The NASCAR door bars, the material and the ten welded mounting points are the same in both versions.
