The perfect images that were used were kindly provided by SiGi from
http://www.esport-racing.de/
You can take the files and copy them into a Murcielago team of your liking.
The wheels should function with every Murcielago that has the standard rims.
You must have activated hi-res wheels ingame to see the rims!
The rims are not "Standalone", this means the rims will appear on all cars of this type if you are driving a race.
Only the textures of the rims have been changed, they have no 3D-depth, this is why they appear so "flat".
Standalone version of the wheelset here.
