AST Weld-in Roll Cage BMW Z3 Roadster V3

The AST Weld-in Roll Cage BMW Z3 Roadster V3 is a full roll cage for the BMW Z3 with 2-door roadster bodywork. This Weld-in Z3 Roadster V3 builds on the V2 and adds door bars, which for the first time give the side of the car real protection as well.

The cage is designed and built by AST Roll Cages in Spain, for drivers who use their Z3 on track often and do not want to skip side protection.

Key benefits

• Door bars absorb side impacts, which is where an open car is most vulnerable.
• Front bars to the bulkhead are retained from the V2.
• Eight welded mounting points make the cage and bodyshell a single unit.
• A stiffer platform for the suspension, noticeable on a short wheelbase such as that of the Z3.
• E355 steel with a 45 mm main hoop and 40 mm for the rest.
• Custom-designed foot plates in 3 mm steel, not universal sheet metal.
• Complete weld-in kit with gussets, documentation and a sticker set.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. Bear in mind that door bars make getting in and out tighter, as they narrow the entry. Before final fitting, check that you can get in and out comfortably wearing your helmet and harness.

The first version that no longer leaves the sides of your open-top Z3 unprotected.

Why choose this Weld-in Z3 Roadster V3 roll cage?

AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that it fits your car exactly. With door bars every millimetre counts, as they have to fit between the seat and the door without restricting your freedom of movement. 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 Weld-in Z3 Roadster V3 is made for the open Roadster. AST does not offer a cage for the Z3 Coupé, so owners of the closed version cannot use this product.

What about the fit?

AST scans the bodyshell of this model with laser scanners and then designs the cage in 3D. So rather than a universal tube kit, you get a structure laid out around the welded mounting points of the Z3 Roadster.
