That's not uncommon with FLY, Scalextric, NSR. Can happen with any car that's held down with a screw. The screws get overtightened, stress from being dropped during shipping, etc. Will not affect the performance of that car. The boiling water and magnet thing....worth trying(?)....I guess...but probably not going to work.
I do have two of the chassis in stock, will post a link as soon I create one.
It becomes a 'problem' when the screws are so tightened that the cracks connect to screw holes and etc. That usually will not happen with FLY, Scalextric as the screw will pull out of the chassis before the cracks really get started.
On NSR chassis there's not much plastic so the cracks do quickly expand to problem size.
Carrera screws are such that it would take a tremendous jolt to cause this to happen.
NINCO. Current screws should not be a problem. The old t-bars, still used on older models, don't crack the chassis but do themselves break this allowing the cars to bang around in the box.

I've had it happen on a few brands. The worst one I had was a Scalextric GT40, and the screw ripped out of the chassis. The plastic was split and misaligned for half an inch in two directions, and the car still ran great. I really thought the car was doomed, but it wasn't a problem at all.
I've had this problem on a few cars and usually a little sanding with a sanding stick gets rid of any bulge that might cause the chassis to bottom out. I also applied some liquid plastic cement that effectively sealed the cracks in the plastic.
Thanks for the replies! Yes, it is image distortion in the picture. The wheels are straight, on my "bling block".
Just got a bunch of Fly Ferrari 512s' in today, and lo and behold, another chassis crack. This one reaches all the way to a front screw hole. Hasn't contacted the screw hole yet, so I'm going to have to find an epoxy to fill the chassis with.
