AST Bolt-in Roll Cage BMW E30 Coupé AWD V4

The AST Bolt-in Roll Cage BMW E30 Coupé AWD V4 is a full roll cage for the all-wheel-drive BMW E30 (the 325iX) with 2-door coupé bodywork. This Bolt-in E30 Coupé AWD V4 includes everything from the V3 and adds an extra diagonal bar and a harness bar, the most extensive level in this bolt-in range. Please note: this is specifically the AWD version, intended for the 325iX and not for the rear-wheel-drive E30.

The cage is designed and built by AST Roll Cages in Spain, for 325iX drivers who compete seriously and want to mount their harness system on the cage in line with the regulations.

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. For this version, the interior behind the front seats must be almost completely stripped; the rear seat cannot stay in. AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that it fits your car exactly.

The AWD V4 is the most extensive bolt-in level for the all-wheel-drive E30 325iX: door bars, front bars, an extra diagonal and a dedicated harness bar.

Why choose this Bolt-in E30 Coupé AWD V4 roll cage?

A harness system is only as strong as the point it is anchored to, and the harness bar of the V4 gives you that fixed point at the right height behind the seat. The extra diagonal bar keeps the main hoop in shape if the car ends up on its roof. Anyone using the 325iX as a serious competition car will end up with this version.

Frequently asked questions

Exactly which E30 is this cage intended for?

The Bolt-in E30 Coupé AWD V4 is made for the all-wheel-drive E30, the 325iX, with 2-door coupé bodywork. If you drive a rear-wheel-drive E30, you need the RWD version; the two are not interchangeable.

Why a separate harness bar?

This version has a cross bar behind the seats to which the shoulder straps are attached within the prescribed angle. Mounting to the original body points rarely meets that requirement in competition.

What is the delivery time?

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