Could you point me towards a tutorial video for this please.... sorry I'm a complete noob.You either have to rename/remove the original data.acd, configure CM to use the unpacked data instead of the data file or re-pack the data folder to an updated data.acd.
There are a few cars I'd like to modify this way so it's worth my time learning the procedure. Also I presume I'd need to keep the original data file for any online races to prevent mismatches?
