AST Multipoint Weld-in Roll Cage BMW E30 Sedan V1

The AST Multipoint Weld-in Roll Cage BMW E30 Saloon V1 is a full roll cage for the BMW E30 with 4-door saloon bodywork. This Multipoint E30 Saloon V1 forms the basis of the multipoint range: a main hoop with backstays that is welded to the bodyshell at ten points. The cage is made for the RWD version, i.e. the rear-wheel-drive E30, and not for the all-wheel-drive 325iX.

The cage is designed and built by AST Roll Cages in Spain, for drivers who want to start with a light, fully welded base frame and build up their car further step by step later on.

Key benefits

• Ten welded mounting points spread the forces over a much larger part of the bodyshell than a bolt-in cage.
• More rigid bodyshell, as the tubes are integrated directly into the structure of the E30.
• Low weight of 71 kg for the complete weld-in kit.
• Custom-made on the basis of a digital measurement of the E30 saloon bodyshell.
• Expandable foundation on which the heavier versions in the range build.
• Complete package with gussets, reinforcement plates and all the mounting hardware.
• Supplied unpainted, so you decide the colour and finish yourself.
• Choice of rear anchorage: when ordering, you specify whether the cage is anchored in the rear suspension area or at the wheel arch.

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. Bear in mind that a weld-in cage is permanent: the interior and trim have to come out before the welder can start.

Ten welded mounting points instead of six bolting points: the most direct way to make an E30 saloon more rigid.

Why choose this Multipoint E30 Saloon V1 roll cage?

A bolt-in cage transmits its forces via six foot plates. This multipoint version does so via ten welded mounting points, spread across the floor, the B-pillars and the wheel arches. As a result, the cage works as a structural part of the car rather than as a separate frame, and you can feel that in the steering response on track.

Frequently asked questions

Does this cage also fit an all-wheel-drive E30 325iX?

No. The Multipoint E30 Saloon V1 is designed for the RWD version, the rear-wheel-drive E30 saloon. For the all-wheel-drive 325iX, AST offers separate cages with different routing around the front axle.

What exactly will I receive?

You receive an unpainted weld-in kit with all the tubes, gussets and reinforcement plates, plus bolts, washers and nuts, documentation, fitting instructions and a sticker set. The tubes are bent to size based on the laser scan of the E30 saloon, so all that is left for you to do is fit and weld.

Where is the roll cage anchored at the rear?

That is up to you. When ordering, you specify whether the cage is anchored in the rear suspension area or at the wheel arch, and AST builds the cage around that choice.
