I dont think i can do that, sorry. It's because, as far as i now, the track layout of Autocross tracks is not in smx files. And that's where the spectator takes the tracks from.
LfS Spectator lets you watch races without beeing on the actual server. You can see where people are and what they do on an upside down view of the track.
To watch the races on a certain server, this server must be registered in Victors relay server, so that the server data can be transmitted. In case you want your own Server to be watchable, you can do this here: http://www.lfsworld.net/?win=hosts&whichTab=insim_relay
Now, when you started the LfS Spectator, just click "Get Server List" to receive a list of the available servers, including the number of drivers on that server. Just select one and click "Spectate" - done.
Changes include a new "look", smoother car movement, ability to set a frame rate (for low cpu usage or smooth graphics) and zoom out to fully visible track.
The download includes the .smx files for all tracks. As usual, please read the readme.txt before posting questions
Expect a minor update in a few weeks, when suggestions made in this forum can be realised.
Edit: for best visual quality (font) use fsaa for OpenGL
Or, since max wheel lock is not only a property of the car, but also of the type of controller you use, maybe an option could be added in the controls menu?
like a "max. lock multiplier", which someone with joystick could set to 1, where his mates whith wheel can set a value of 2 oder 1.8 oder something like that..
