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.

2023-02-25 - Early E36 sway bar end links

Q:
At impound on Sunday morning an issue was raised with our car about having the M3 front sway bar end links. I was pretty sure I used the same end links that came with the car when I built it, so I did a little digging. It sounds like the early E36's had end links that dropped down from the strut, just like the M3s.

Here is a forum post about it:
https://www.bimmerforums.co.uk/threads/e36-differences ... ost-485528

"As far as the "early" 1992 325s.... The 1992 325i/325is built before June of '92 use all the same front suspension mounting locations as the later cars, but the struts, spring diameters, and strut mounts are all a little different. Also, the swaybar attaches to the strut body with a droplink, which is how it is configured on all E36 M3s, rather than to the control arm, as it does on all other E36s. The rear is the same as other E36s."

I completely understand that this forum post should in no way be official proof of the end links being legal for my year of E36, at least there is some discussion about it. Is there anything you need from me in order to get an official ruling?


A:
You are absolutely correct.

For legacy recording of information:
PN 31351134582 is for e36 325i and 325is USA spec cars up to 10/91, Chassis sub-code CB33/43 (sedan) and BF 33/43 (Coupe).
The above PN are therefore considered original equipment for any M50 powered e36
