ChampCar Tech Desk

Official channel for ChampCar technical questions, interpretations, and VPI requests.

Before you submit a ticket

The Tech Desk is for rules clarifications and technical questions. It is not a post race tech line, a place to protest results, or a place to fish for how other teams built their cars.

Most questions can be answered by reviewing the current BCCR Rulebook. Please read the applicable section before submitting a ticket.

If your question is already covered clearly in the BCCR, your ticket may simply be answered with a reference to the rulebook section.

VPI request checklist

For all Vehicle Performance Index (VPI) requests you must include:

  • Year, make, model, and trim level
  • Engine size and engine horsepower
  • Drive type: FWD, RWD, AWD, or 4x4
  • Transmission type: automatic or manual
  • Car weight and all factory options that affect performance
  • A link to the vehicle on automobile-catalog.com or another site with full specifications if it is not listed there

Requests that do not include all required info and research will be denied without review.

2021-01-01 - Roll Cage Tabs

Q.
Looking to add tabs to connect my A-Pillar bars to my A-Pillar. I would like to make the tabs ~10" long. However 3.2.11.2 states tabs can be 6" max length with max 2 tabs in any 36" of tube. If this is the only tab in 36" of tube can I make it 12" long or do I need to make two separate 6" plates that are say 1/4" apart. Either way is fine, just want to make sure I'm not taking the rules outside the spirit of their design.

A.
Please use two separate tabs per side, max 6" each, to attach your A pillars to each side of the car.


2022-01-23 Update
Per our BCCR:
3.2.10.2.The total number of mounting points does
NOT include welded tabs connecting any
hoop to the body. A “tab” is defined as being
not greater than 3/16” thick steel plate, no
longer than six inches (6”), and a maximum of
two (2) tabs may be placed within any 36” of
tube.

Additional tabs and/or tabs exceeding allowable dimensions will be charged materials points
