I am at a loss on these cars. they have yellow tail lights. What car has that? I have not noticed the LOD issue yet but I would not hold my breath for an update as these cars were supposed to be released many months ago.Just a heads up to anyone using the current beta version of Chivas' Group 3 cars, bad physics or not, you might want to consider going into the LOD.ini file in the data folder and erasing the LOD3 data, or deleting that LOD from the car's folder entirely. It can cause the cars to turn solid black at a distance that looks awful during a race.
They will probably fix that later on considering it's an early release but for now it may be worth doing if you've noticed it and weren't sure what to do about it.
