ChampCar Endurance Series

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.

2021-01-03 - C4 Corvette Roll Cage

Q.
I am building an 89 Corvette I plan to race in ChampCar Endurance Series. As I am designing the roll cage I can see that due to the configuration of the car I don't think I can do a traditional main hoop, since the floor comes up directly behind the driver seat.

Question is can I attach the door bars to the floor behind the driver seat as shown in the attached picture? And if so is this the preferred method for a C4 Corvette cage to be designed?
C4 door bar example


A.
Looks good.
Base plate needs to be bigger to center the door bars on the plate. Definitely prefer the single bend door bars vs. the reverse bend.
