Love Cadillac’s attitude on their racing pages:

IT ISN’T SO MUCH A WILL TO WIN AS
IT IS A REFUSAL TO FOLLOW.
Where do you go when you’ve proven you can build one of the world’s most acclaimed production cars, the 556 horsepower Cadillac CTS-V? To the racetrack, to make it even better. This season, Cadillac joins North America’s top production-based race series, the Sports Car Club of America World Challenge. Our competitors are going to get very used to watching these taillights.

The CTS-V Racers are prepared by Pratt & Miller

The V Racer colors are probably done using a vinyl wrap.  That makes it quick and easy to get the same effect every time,  after repairs, etc.

I would like to see Cadillac offer a wrap like this as an option for Customer Cadillac CTS-V Coupes.

Yes, I know it is not a conservative look  for a road car, but this is the sort of thing that some Customers might enjoy.

And it certainly would be remarkable to pull up next to one at a stoplight.
