AST Weld-in Roll Cage BMW E30 Sedan AWD V4 NASCAR door

The AST Weld-in Roll Cage BMW E30 Saloon AWD V4 NASCAR Door Bars is a full roll cage for the all-wheel-drive BMW E30 (325iX) with 4-door saloon bodywork. This Weld-in E30 Saloon AWD V4 NASCAR builds on the V3 and adds an extra diagonal bar and a harness bar, with NASCAR door tubes in both doors instead of the standard door bar.

The cage is designed and built by AST Roll Cages in Spain, for drivers who use their 325iX seriously on track, in drifting and in rallying, and want a permanently welded-in structure with a high level of specification.

Key benefits

• Extra diagonal bar gives noticeably more torsional rigidity than the V3 in the same family.
• Harness bar provides a fixed, correctly positioned mounting point for the shoulder straps of your harness.
• NASCAR door design with several curved tubes in the door instead of the standard door bar.
• More side protection, because the curved tubes cover a larger area of the door.
• More room to get in thanks to the shape of the NASCAR door tubes.
• Eight welded mounting points spread the forces across the bodyshell of the E30 saloon.
• Designed around the 325iX, the all-wheel-drive version of the E30.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. Have the welding done by an experienced welder, as the eight welded mounting points and the gussets must sit in exactly the right place in the bodyshell. AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that it fits your car precisely.

A V4 weld-in cage with NASCAR door bars gives the all-wheel-drive E30 Saloon extra side protection without making it awkward to get in and out.

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

The V4 sits at the point where rigidity and usability strike a good balance: you get the extra diagonal brace and the harness bar, but keep a cage you can get in and out of every day. The NASCAR door bars actually make the latter easier than with a straight door bar. Because the cage has been designed specifically for the 325iX, it runs clear of the front driveline.

Frequently asked questions

What is the difference between NASCAR door bars and a standard door bar?

On this Weld-in E30 Saloon AWD V4 NASCAR, several curved tubes sit in the door instead of the single standard door bar. This gives more side protection and more room to get in at the same time.

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

No. This version has been designed around the all-wheel-drive E30 (325iX). If you drive a rear-wheel-drive E30 Saloon, choose the RWD version.

What exactly will I receive?

You receive the unpainted weld-in kit with gussets, reinforcement plates, bolts, washers and nuts, documentation, the fitting instructions and a sticker set. The cage is intended for track and competition use; always check the regulations of your own organiser.
