Mods not appearing after putting into respective folders

[Lesthegringo]

Hi all

I've just downloaded the McClaren MP4/20 and it's clear that the contents of the download are supposed to go into the contents folder, which I have done.

Unfortunately, like with other mods I've downloaded, they are not appearing in game. I went to VSC in the car selection menu , and the only car in there is the Jordan, and in the McClaren menu it shows the MP4/13 but not the MP4/20.

I accept it is probably my fault, if anyone can advise on what I should be doing I would be grateful!

Cheers

Les
