I havnt got the game yet but do I have to download layouts from websites or are they already in the game? Thanks!

Be nice if you didn't shout and spam all over the forum - one post could have done for both your questions - one of which has been answered, but just in case...

sets - these go in LFS/data/setups folder

layouts - look in this forum for the Files section, then Autocross Layouts - or if you can't be bothered looking for it, or use the search function, then look here. Will require that you have a S1 license to use them.

Also use the FAQ section and read the manual.

Any more questions can be asked on a post you've already opened.

I can recommend the karting tracks, particularly the bigger one (National IIRC) on Westhill, but for access to that you have to upgrade to at least S2 licence.
