Very high quality mod, inside and out. I only ran into 1 issue, and I think it's more of a game-wheel limitation rather than anything on the mod-side.
I had the same issue I did with the F40 and Yellowbird, where the cars have 900+ degrees of steering, and my G27 only has 900, and the game alters the steering rate of the in-game wheel, meaning if I put-in 90 degrees of steering, the in-game steering is doing more than 90 degrees, causing it to fall out of that 1:1 ratio.
Would be nice to see a '900 degrees' version, or just an optional file for G27/Logitech wheel users.
I made a mistake with the folder hierarchy, so you have to make a mazda_miata folder manually in AC cars folder and put the files into it. I will update the link with a help of an admin soon so you don't have to do this in the future.
You can find the proper link at AC forum until we can update the link here. Apologies for the mistake.
