AST Weld-in Roll Cage BMW E30 Touring V4 NASCAR door

The AST Weld-in Roll Cage BMW E30 Touring V4 NASCAR Door Bars is a full roll cage for the rear-wheel-drive BMW 3 Series E30 with 5-door Touring bodywork. Instead of the standard door bar, this Weld-in E30 Touring V4 NASCAR has several curved tubes in the door, plus the extra diagonal brace and harness bar of the V4.

The cage is designed and built by AST Roll Cages in Spain, for drifters who run close together and want both more side protection and more room to get in and out.

Key benefits

• NASCAR door bars: several curved tubes in the door instead of a single straight door bar.
• More side protection: the load in a side impact is spread over several tubes.
• More room to get in: the outward curve towards the door makes it easier to get in and out.
• Harness bar: a fixed anchor point for the shoulder straps.
• Extra diagonal brace: keeps the main hoop in shape.
• Eight welded mounting points: permanently welded to the bodyshell for maximum rigidity.
• Unpainted weld-in kit: with gussets, reinforcement plates and complete mounting hardware.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. The NASCAR tubes extend into the door, so the door cards have to be modified or replaced. The welding is permanent and should be carried out by a specialist.

The NASCAR door bars give you two things at once: more steel next to your hip and yet easier entry.

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

In drifting, side contact is the rule rather than the exception. The curved tubes in the door keep the cockpit open and spread the impact, while also creating room exactly where your shoulder would otherwise hit a straight tube. Combined with the harness bar of the V4, you get a complete, fully functional safety set-up.
