Before I read it I thought they meant with the next Cadillac GTP. After I read it I double checked the date

I saw it on today's Racer.com mailing list - but I wasn't sure what to think of it.
Now that I've had a chance to 'process' it a little bit, I'm still not sure I know what to think of it!
We'll see.

I don't recall seeing the actual weight, but NASCAR cars have a good bit of ballast to get them to the weight requirement.

Honestly they're not actually all that heavy. 3300lb is 1495kg. V8 Supercars are 1395kg and built quite similarly so I suspect there is a heap of ballast in them.

I wonder how much of an issue brakes will be?

Credit where it is due. That looks and sounds bloody good although mirrors and dive planes will take some time to get used to

Does this mean that they'll have to make the headlight stickers light up?
