I don't know if this thread on the right place here but i got a problem with a tweak i installed. It changed the body and interior of the xrg and xrt into a bmw m3. Now i want uninstall this so i've got the original cars back. Could somebody help me? And sry for the langue, i don't talk english, so...

It's always a good idea to make a backup of any files before you tweak them, for this very reason. There's not really anyway to fix it except to uninstall LFS and reinstall it. If you know which files have been changed you can get replacements from a friend who has an unmodified copy of the game and just paste them in. If not then backup all your setups/replay etc.. and reinstall the game.

Does somebody have the original files of the XRG and XRT, i've installed a tweak on these cars and i don't know how to untweak them :doh:

Please, don't mod them again. It's not allowed too.
At least not online.

[E] Put them in your "LFS\data\veh" folder.
