Quote from Shotglass :

i think bobs files still use the old setup prefixes eg "XR GT TURBO_" you have to change them to the 3 letter codes to make them work in patch y eg "XRT_"
theres a few tools floating around the forum that will do the job for you if you dont want to rename them manually

Ah yea...I finally realized that after poking around a bit. If I want to change the file names manually is there a list somewhere of what the three letter code is for each car?

Thanks.

I just downloaded bob's extensive list of car set files and put them in my setups folder, but they don't show up in game.

Is there something I need to do to actually import the set files?

Thanks
