AST Bolt-in Roll Cage BMW E30 Sedan AWD V4

The AST Bolt-in Roll Cage BMW E30 Sedan AWD V4 is a full roll cage for the all-wheel-drive BMW 3 Series E30, the 325iX, with 4-door saloon bodywork. This Bolt-in E30 Sedan AWD V4 has front bars, door bars, an extra diagonal brace and a harness bar, and is designed for the all-wheel-drive E30 (325iX).

The cage is designed and built by AST Roll Cages in Spain, for 325iX drivers who compete and want a structure in which bodyshell, cage and harness system work as a single unit.

Key benefits

• Harness bar: your four-point or six-point harnesses are anchored to the cage instead of the bodywork, so the angle of the shoulder straps is correct.
• Extra diagonal brace: the main hoop is braced within itself and holds its shape better in a rollover.
• Door bars and front bars: everything from the V3 is included, supplemented by the extra bars.
• Specifically for all-wheel drive: designed around the different floor and transmission tunnel of the all-wheel-drive E30.
• FIA homologation: AST states homologation number 5348, valid for the BMW 325iX according to FIA Appendix J.
• Six bolting points: bolted onto six foot plates in 3 mm steel that are welded to the bodyshell.
• Complete and unpainted: including connecting sleeves, reinforcement plates, bolts, washers, nuts, documentation, fitting instructions and a sticker set.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. Before fitting, fix the seating position of your bucket seat, because the harness bar needs to sit at the right height behind your shoulders. The six foot plates are welded to the bodyshell and the cage is then bolted onto them, so expect some welding.

The V4 includes everything a 325iX needs for competition use, right down to the anchor point for your harness.

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

A harness is never stronger than the point it is anchored to. With the shoulder straps attached to a harness bar on the cage, the angle stays correct and an impact does not pull on thin sheet metal behind the seat. The extra diagonal keeps the main hoop in shape. AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that all the bars in this 325iX end up in the right place.

Frequently asked questions

What is the harness bar for?

The harness bar is the anchor point for the shoulder straps of your harness. On the Bolt-in E30 Sedan AWD V4, your harness is therefore anchored to the cage instead of the parcel shelf, which gives much better load absorption.

Does this cage also fit a rear-wheel-drive E30?

No. This version is made for the all-wheel-drive E30 (325iX). If you drive a rear-wheel-drive E30 saloon, choose the RWD version of this cage.

What is the delivery time?

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