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.

2020-08-17 - Droop Limiters / Spring Retainers

Q.
I would like to know the point value for Droop limiters.

Cable, chain, strap etc used to limit the suspension extension and keep the spring in place.

A.
Most teams that are running cars without captured springs that are using non OEM hardware or components to hold the spring in place are using this rule:

4.7.5. Hardware, fasteners, and materials used to attach things to
other things (nuts, bolts, screws, rivets, duct tape, bailing
wire, zip ties, JB Weld, etc.) are open.
