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.

2021-11-22 - SFI/FIA seat back with sliders

Q.
We are installing an FIA/SFI fixed back seat and are mounting it on sliders. Rule 3.3.4 says, in part, that a seat back brace is not required for any “ permanently mounted “ seat. Assuming we use the correct hardware, will our seat meet the definition of permanent and therefore not require a rear seat back brace.

A.
We do not consider a seat mounted on sliders as permanently mounted as many of the slider systems we see are not up to the task. We do not want you to mount a back brace to your FIA seat but we do want a brace to be within 3" of the seat at all times. So your brace can be adjusted along with the seat when the seat is moved forward.
