Hey! Good to see some more progress on the Challenger, I only have a few things about the new bumpers.
The concept lightbar actually had the Dodge writing on it, the difference was the reverse lights were next to the license plate rather than on the actual light bar.
Now before you read the next part I have to ask, is the entire front of the challenger the bumper? If so then I'd maybe either want you to look up some more images of the Hellcat bumpers or maybe look at the 2015 Challenger that was featured in Horizon 2 recently.
I'm in no position to tell you how you should make the custom parts for the challenger, but if you want to make these changes then they would certainly go appreciated.
