I was in a rush posting yesterday and it occurred to me that there maybe issues just dumping a KN5 into another car folder, such as animations. Here's the full car folder as that maybe easier and cause less errors. Although obviously up to you if you'd rather not use it.

@ukzz4iroc - see above, sorry for confusion
Hi @GIBBONS - I tried this as a fresh install and get the same effect as I did when I copied your kn5 over the 'original'. Dashboard is borked and the rims have strange effects going on. It's not right. Thanks for trying.
