In my opinion, there are a few problems with some of the current included cars in the mod:
1- AT Racing uses completely different skins between its driver 1 and driver 2 and that way it will be confusing for the broadcast to know they are from the same team. I think team identity is lost this way.
2- GT Omega is using the number 1 in their WT car but they should use the number 0 instead, because the number 1 should be reserved to the champion driver only.
3- Flying Finns car is too bright, probably because of wrong alpha channel.
That's just my opinion.
