with all the work we're doing on Papa Smurf, one of big pieces of the development is tying the roll cage to the rear and front suspension points, plus doing tubing to strengthen other points around the car.
Would like to see how people run the tubes from the roll cage, through the fire wall or window, through the engine compartment area, into the rear trunk to the shock towers. We have things in the way there, but will move around if needed.... Thanks! |

That style cross brace in the halo will collapse inward on roll over ask me how I know (IMG:style_emoticons/default/sad.gif)
Here's a FIA legal one https://www.customcages.co.uk/roll-cages/porsche-914 |

If I were doing the chassis, I would cut the current "roll cage" out altogether. I know its a pain in the ass, but there are way too many compromises in said "roll cage".
There is no lateral brace connecting the a-piillar bars at the door bar intersection and the main hoop door bar intersection. This will lead to a collapse inward should you take a hit in the door bar. The door bars will simply fold the cage up like a wet noodle. That looks like an Autopower type cage. Very old and poor design. Once you pull the dash out of the car you can push the a-pillar bars further out to properly support the front of the car. Then build a proper dash bar supports and triagulates the door bars, with the A-pillars, and the strut tower bars. You will want to go through the firewall and connect the shock towers to the a-pillars, and you want to come down to the base of the a-pillar bars to keep the front of the car from folding into your feet. As for the rear suspension you want to connect the rear shock towers to the main hoop and connect the rear suspension mounting points to the main hoop. The rear suspension mounts flex terribly and tying them into the roll cage will make the car more comfortable to drive. |

Side bars were added to meet SCCA requirements. The rear braces go through the rear window and attach to the shock towers. |

Check out my F-914 build in my signature. I have Chris Foley's roll cage that I added to.

That cage is of questionable legality for SCCA and NASA, probably PCA and POC as well.

Without a full width main hoop crossbar that cage is not legal for SCCA Club Racing.
