AST Multipoint Weld-in Roll Cage BMW E30 Coupé V1

The AST Multipoint Weld-in Roll Cage BMW E30 Coupé V1 is a full roll cage for the BMW E30 with 2-door coupé bodywork. This Multipoint E30 Coupé V1 is the entry level of the multipoint range: a main hoop with braces that is welded to the bodyshell at ten points. Important: this is the cage for the rear-wheel-drive E30. A separate cage is available for the all-wheel-drive 325iX.

The cage is designed and built by AST Roll Cages in Spain, for drifters and track drivers who are building up from a bare shell and want to give their E30 the most rigid possible foundation right from the start.

Key benefits

• Ten welded mounting points instead of the eight on a standard weld-in cage, so the forces are spread across more points in the bodyshell.
• More rigid bodyshell that lets the suspension do its job, which you will notice in calmer and more predictable handling.
• Permanent connection to the bodyshell, without the play that can develop over time with a bolted joint.
• Custom-scanned, as AST digitises the E30 bodyshell and draws up the tubes in 3D.
• Kept light at 71 kg for a full structure, thanks to E355 steel in 45 and 40 mm.
• Complete package with gussets, reinforcement plates, bolts, washers, nuts, documentation, fitting instructions and a sticker set.
• Spacious interior, as the V1 does not yet have door bars and you can get in and out easily.
• Available with anchorage in the rear suspension area or at the wheel arch, which you choose when ordering

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 cage welded in by an experienced welder, with the interior stripped out and the battery disconnected; the gussets and reinforcement plates are welded in at the same time, in the positions specified by AST.

Ten welded mounting points instead of eight: the V1 is the lightest way to make an E30 bodyshell truly rigid.

Why choose this Multipoint E30 Coupé V1 roll cage?

Anyone building up their E30 step by step wants a foundation that will not get in the way later. The Multipoint E30 Coupé V1 gives you exactly that: the full structure with main hoop and braces, permanently welded in at ten points, without the extra bars you may not need yet at this stage. The steel and the fit are identical to the heavier versions, so you are building on the same foundation.

Frequently asked questions

What is the difference from a standard weld-in cage?

A standard weld-in cage is welded to the bodyshell at eight points. This Multipoint E30 Coupé V1 uses ten, supplemented by gussets and reinforcement plates. As a result, the load is spread over a larger area and the bodyshell becomes more rigid.

What exactly will I receive?

You receive an unpainted weld-in kit: the tubes of the structure, gussets, reinforcement plates, bolts, washers and nuts, documentation, fitting instructions and a sticker set. You do the painting yourself after welding.

Does this cage also fit a 325iX?

No. This cage is custom-made for the rear-wheel-drive E30 Coupé. The all-wheel-drive 325iX has a different floor and tunnel and requires a separate cage.

Where is the roll cage anchored at the rear?

You specify this yourself when ordering. You choose between anchorage in the rear suspension area and anchorage at the wheel arch, and AST builds the cage accordingly.

What is the delivery time?

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