AST Weld-in Roll Cage BMW E21 Coupé V5

The AST Weld-in Roll Cage BMW E21 Coupé V5 is a full roll cage for the BMW 3 Series E21 with 2-door coupé bodywork. This Weld-in E21 Coupé V5 is the most comprehensive specification in the range: the complete set of bars, with nothing left for you to add later.

The cage is designed and built by AST Roll Cages in Spain, for drivers who want to get the maximum out of their E21 in one go and have no intention of ever cutting the cage open again for additions.

Key benefits

• Complete set of bars with everything from the V1 to the V4 in a single structure.
• Maximum torsional rigidity for a compact classic that was never designed for it at the factory.
• Eight welded mounting points permanently spread the load across the bodyshell.
• E355 steel, 45 mm for the main hoop and 40 mm for the rest of the structure.
• 3 mm steel foot plates, custom-designed for each car from a laser scan.
• No extra work later on, because all the bars are in place from the initial build.
• Supplied unpainted with gussets, reinforcement plates, mounting hardware, documentation and a sticker set.

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. Allow for extra labour hours with this version: the more tubes, the more welding, and the interior has to come out completely.

The V5 is the complete set in one go, so you never have to cut the cage open again to weld in extra bars.

Why choose this Weld-in E21 Coupé V5 roll cage?

Welding extra bars into a cage that is already in the car is expensive and messy. If you know you will end up wanting everything anyway, the V5 works out cheaper than putting the car on the lift twice. You also get the most rigid structure AST designs for the E21 Coupé.
