AST Bolt-in Roll Cage BMW E30 Coupé V3

The AST Bolt-in Roll Cage BMW E30 Coupé V3 is a full roll cage for the BMW E30 3 Series with 2-door coupé bodywork. This Bolt-in E30 Coupé V3 includes everything from the V2 and adds door bars in both doors, the point at which the cage also starts to protect the driver from the side. Important: this cage is made for 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 compete in events where door bars are often already mandatory under the regulations.

Key benefits

• Door bars on the left and right, the most important step in side protection.
• Front reinforcement bars to the bulkhead, carried over from the V2.
• Six bolting points on six foot plates welded to the bodyshell.
• 45 mm main hoop in E355 steel, the rest of the structure in 40 mm.
• Torsionally rigid unit, as the front, side and main structures together form a closed frame.
• Removable design with connecting sleeves, including all mounting hardware.
• FIA Appendix J as the design basis, with homologation numbers for this model.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. The six foot plates are welded to the bodyshell and the cage is then bolted onto those plates. The door bars run through the door area, so the door card and often the original trim have to make way. AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that it fits your car exactly.

With door bars in both doors, the V3 is the first version that genuinely shields the driver in a side impact too.

Why choose this Bolt-in E30 Coupé V3 roll cage?

Side impacts are the most common scenario in drifting and track use, and that is exactly where a cage without door bars offers little. The V3 closes that gap and also makes the frame more torsionally rigid, because the front section, sides and main hoop now form one continuous unit. For many competition classes, this is the level at which you can take the start without modifications.

Frequently asked questions

Can I keep my original door cards?

Usually not entirely. The door bars of the Bolt-in E30 Coupé V3 run through the space occupied by the original card, so expect modified or replacement door cards on the driver’s and passenger’s side.

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

No. This version is intended exclusively for the rear-wheel-drive E30 Coupé. A separate AWD version of this roll cage is available for the all-wheel-drive 325iX.
