for the ones who would like to use the set in csm here's a quick way to do it:
install the carset to a fake temporary directory. for example: c:\temp\
create a new folder in your carset map and choose any name you like.
copy all the files except de cars directory and the uninstall.exe to that carset directory
download
this file and rename it to .csm
place in inside the carset dir, and happy racing
ps.
don't try to change things like tracks specific wads etc.. because that is already working this way.
csm mainly uses the swap function for most files in this carset, and if you adjust the same settings by hand it'll probably confuse csm.
mister csm 0.972 is not that smart you know...
oh sidenote.. if you normally don't use the 9.6 patch, and you still want to play it, then move the cars dir from the install to your gp4 root dir.
don't worry... you can't ruin anything if you don't have the 9.6 patch installed.
otherwise its not necessary
