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.

2019-11-28 - BMW Bumper Covers

BMW 3-Series bumper covers

Rule 4.7.6. Replacement of OEM Parts /

Tech interpretation and enforcement of BMW 3-Series bumper covers is that E30’s cannot use E36 covers.  E36’s may use aftermarket E36 M3 replacement cover but must remove lower “lip” or pay 10 points as a splitter.

The 1994 E36 BMW came from the factory with all the M tec (M3) bodywork which makes the M3 bodywork legal for the E36 platform.
