ChampCar Tech Desk

The tech desk is used to ask technical questions and is not to be used as a post race tech line or to phish for how others built their cars. Please reference the BCCR as most questions submitted to the TechDesk can be answered by reading the BCCR. You can download the BCCR here:
VPI requests require the year, make, model, trim level, engine size, engine HP, Drive type (FWD, RWD, AWD, 4x4), auto or manual transmission, car weight, and all options. Your request will not be answered if you do not include all of that information. You must use for all of your information submitted. Include the link to the automobile catalog so we can quickly reference the data. If your car is not listed on that website, please link any website that has the info. If you do not include your research info above, your request will be denied.
Thank you.

2020-03-20 - Aero pan

What are the width limits of an aero pan? Is it the extreme widths of the car like a wing? Is it the width or the rocker panels? Or is it the width of the punch welds?

If you are paying points for non-oe rocker panels as an aero device or have OE rocker panels, the flat panel can be attached to, but not replacing the OE floorboards and extend horizontally to the vertical edge of the rockers. It cannot extend beyond the single plane vertical edge of the non-oe or OE rockers.

If you do not have rockers and are not paying points for aero rockers then the flat tray cannot be extended beyond the OE pinch welds.

If you are in doubt submit descriptions and photos of your flat tray mounting for approval to avoid surprise points at tech inspection.
