AST Multipoint Weld-in Roll Cage BMW Z3 Roadster V1

The AST Multipoint Weld-in Roll Cage BMW Z3 Roadster V1 is a full roll cage for the BMW Z3 with 2-door roadster bodywork. This Multipoint Z3 Roadster V1 is welded to the bodyshell at ten points instead of the eight of the standard weld-in cage, making it more rigid.

The cage is designed and built by AST Roll Cages in Spain, for drivers who, even with the base version, opt for the strongest mounting method AST offers for this model.

Key benefits

• Ten welded mounting points instead of eight: two extra places where the cage transfers load into the bodyshell.
• More rigid than the standard weld-in cage at the same specification level.
• Lower local loads because the forces are spread over more points.
• Especially valuable in an open car, where the bodyshell has to manage without a roof.
• E355 steel, main hoop 45 mm and rest of the structure 40 mm.
• Foot plates in 3 mm steel, custom-designed for each car.
• Supplied unpainted, including gussets and fitting instructions.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. Ten welded mounting points also means ten areas that must be bare and rust-free before any welding is done. Have this preparatory work carried out by a professional.

Two extra welded mounting points may sound minor, but they determine how the cage can transfer its loads.

Why choose this Multipoint Z3 Roadster V1 roll cage?

AST digitises the bodyshell with laser scanners and designs the cage in 3D, so it fits your car exactly. As a result, the extra welded mounting points sit precisely where the Z3 is strongest. The cage is intended for track and competition use; always check the regulations of your own organiser before ordering.

Frequently asked questions

Does this cage also fit a BMW Z3 Coupé?

No. The Multipoint Z3 Roadster V1 is designed around the open bodyshell of the Roadster. AST does not offer a cage for the Z3 Coupé, so owners of the closed version should not order this product.

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

The tube specification is the same, but the multipoint version is welded to the bodyshell at ten points instead of eight. This makes the structure more rigid.

What is the delivery time?

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