Tube by Tube

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). view image

Dash bar

Improves rigidity and side impact strength. view image

Door X bars

Upgrades single door bar for significantly improved side impact protection; improves door aperture stiffness. view image

Front cross

Improves lateral stiffness of strut tops and bulkhead. view image

Hoop to A pillar tube

Designed to improve support for A pillars at roof level. view image

Hoop cross

X section now required by the latest regulations to improve roll over protection. view image

Lower rear stay

Triangulates loads from the rear struts so improving rigidity.
view image

Mid rear stay

Adds further stiffness to rear section; improves side impact strength.
view image

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. view image

Rear X

Stronger than the simple single diagonal tube. Gives additional strength to rear damper mounts. view image

Roof cross or roof 'V'

Increases roll cage rigidity and safety in the event of a roll over; essential in later model rally cars. view image

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. view image

Seat harness tubes

Needed for wrap-over seat belts. Safety improved with shorter belt length and better belt angle. view image

Single roof diagonal

Lighter than a full roof cross but provides less protection – acceptable for race cars. view image

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. view image

Tunnel brace

Improves side impact protection and supports the main hoop in the event of a roll over. view image
