ChampCar Tech Desk

The tech desk is used to ask technical questions and is not to be used as a post race tech line or to phish for how others built their cars. Please reference the BCCR as most questions submitted to the TechDesk can be answered by reading the BCCR. You can download the BCCR here:
VPI requests require the year, make, model, trim level, engine size, engine HP, Drive type (FWD, RWD, AWD, 4x4), auto or manual transmission, car weight, and all options. Your request will not be answered if you do not include all of that information. You must use for all of your information submitted. Include the link to the automobile catalog so we can quickly reference the data. If your car is not listed on that website, please link any website that has the info. If you do not include your research info above, your request will be denied.
Thank you.

2020-02-27 - Bolt-in Roll Cage

If a bolt-in roll cage has had all seams welded (i.e. not bolts used anywhere)pass tech, assuming all other requirements are met (i.e. tubing size and thickness/ design/ sufficiently sized spreader plates, etc)?
I do not have a specific vehicle to assess, but it is a question I've been asked about older SCCA/NASA cars and whether they can be brought up to modern safety standards.

I would prefer to approve modified bolt-in cages on a case by case basis. 
If you have a modified bolt-in roll cage you should confirm that the tubing diameter and wall thickness is in compliance with current rules and then confirm all design components are compliant.
