First Look: Full Containment Door Bars

Written by Adam Doyle on Apr 3, 2026

We've been working on a third door bar option for the V2, and the first mockup is on the chassis.

The new option is the full containment door bars, or full door bars for short. They sit alongside the existing Easy-Entry and Standard door bars. The mockup in the photo below is on V2 chassis #002.

What "Full Containment" Means

The full containment door bars come higher up than either of the other two options (and slightly higher than the full door bars of V1). Where the Standard door bars give you two horizontal tubes at door height, full containment adds a third horizontal bar to better enclose the occupants.

The point of all that extra tubing is side intrusion protection. Full containment is the most protective configuration we've designed for the Goblin. If side impact protection is high on your list, this is the option that gets you there.

How They Compare

The graphic above puts Standard on the left and full containment on the right. Standard, previously called the Double or Mid door bars, is the configuration most similar to the door bars of V1. Two horizontal tubes at door height give you protection across the most common side impact zone.

Full containment takes the same idea and keeps building on it. The added tubes raise the protection envelope above where the Standard bars sit, so you're getting structure higher up. More tubing, more coverage, more enclosed feel from inside the car.

The third option, not shown in the graphic, is the Easy-Entry door bars. As the name suggests, Easy-Entry is the most forgiving configuration when it comes to climbing in and out of the car. The tradeoff is that it leaves the side of the car more exposed than either Standard or full containment, so you're trading some protection for a much easier daily-driving experience.

The Tradeoff

The same tubes that give you the protection also make it harder to get in and out of the car.

With Easy-Entry, getting into the Goblin is something most builders can do without thinking. With Standard, it's a step-over but still manageable. Full containment is a real climb. You're stepping over, ducking under, and folding yourself into the seat in a way that takes practice the first few times.

The full cage option compounds this. Pair full containment door bars with the full cage and you've built yourself a serious car to climb into. Pair them with the T-top and the situation is more forgiving, since there's no horizontal cage bar above your head to clear.

For a track car or a hill climb car where you're geared up and committed to the run anyway, full containment makes a lot of sense. For a daily driver where you're getting in and out a dozen times a day, they probably don't.
