As we're getting close to the end of the year, we will aim to finalise the rulebook soon, hopefully by Christmas. This will give you at least a couple of months to work on your first entries. Calendar and information on CFD testing will follow early next year.
Pre-registration is open here:

You can now contact me at chris at khamsinvirtualracecarchallenge dotcom (or through PMs). As we get closer to the start of the season, I'll strongly encourage everyone to submit a copy of their car to me if there are any doubts or concerns about compliance with all of the rules. Similar to previous years, there will be points penalties if the entry submitted for the points-scoring rounds doesn't comply with the rulebook.
A new version of the rulebook is available here: http://www.mediafire.com/view/vdmx76qx5 ... rdraft.pdf
The updated guide files will follow a little later. The main rule changes:
K1.2 - Thin parts may now be 10mm thick instead of 20mm, and wording was included governing the leading edge.
K2.6 - Examples have been given for how bodywork may intersect the suspension volumes. The suspension volume parts have been changed slightly in that they now extend outwards all the way to the wheel, but the region inboard of that hasn't been changed.
K3.1 - Front crash structure area requirement is now at a plane 700mm forward of the front wheel centerline. Changed minimum area to 24000mm^2 and added constraint of no less than 100mm wide or high.
K3.3 - Added rule specifying a single curve must be formed when the diffuser surfaces are intersected with a plane normal to the X-axis, with an exception made for exhausts, if these exit inside the diffuser.
K4.2 - All outlet surfaces must be located at least 600mm rearwards of the rearward-most point of any cooling inlet surface.
Added to the list of options for rules on the sidepod area - a rule specifying that the side impact structure parts (supplied) must form part of the car, with some freedom on positioning. I would welcome any feedback on this rule, for the moment this is just an option. Still undecided on which of these rules, if any, we will use.
Also I'd like to hear if there are any rules in there which are particularly confusing or complex, since we would like to make the rulebook a bit easier to understand compared to 2014.

These will be included in future releases of the guide files if we go ahead with this idea.
