What Does Each Tube Do In a Roll Cage?

A quick guide to what each tube does in making the roll cage as strong and safe as possible.

A post gusset – Improves strength as the cage A pillar can be welded to the screen pillar (not applicable to all models).
Dash bar – Improves rigidity and side-impact strength.
Door X bars – Upgrades single door bar for significantly improved side impact protection; improves door aperture stiffness.
Front cross – Improves lateral stiffness of strut tops and bulkhead.
Hoop to A pillar tube – Designed to improve support for A pillars at roof level.
Hoop cross – X section now required by the latest regulations to improve roll over protection.
Lower rear stay – Triangulates loads from the rear struts so improving rigidity.
Mid rear stay – Adds further stiffness to rear section; improves side impact strength.
Rear strut brace – Improved bodyshell stiffness enhances handling by feeding suspension loads into the base of the roll cage; can be used or seat harness mounting in some models.
Rear X – Stronger than the simple single diagonal tube. Gives additional strength to rear damper mounts.
Roof cross or roof ‘V’ – Increases roll cage rigidity and safety in the event of a roll over; essential in later model rally cars.
Screen pillar support – Important for latest generation saloons with a steeply raked windscreen to provide additional support to the top of the A pillar/roof section. Now required by the latest FIA regulations.
Seat harness tubes – Needed for wrap-over seat belts. Safety improved with shorter belt length and better belt angle.
Single roof diagonal – Lighter than a full roof cross but provides less protection – acceptable for race cars.
Triangulation tubes to front struts – Allows the front suspension loads to be fed into the whole cage structure; provides protection for occupant’s feet. It also improves side impact protection and increases the load capacity of the ‘A’ pillars/lateral hoops.
Tunnel brace – Improves side impact protection and supports the main hoop in the event of a roll over.

What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
