Is it? That is something I don't know.
I know a few factory car that come with larger wheels as standard such as the Dodge Viper, but I guess that is in America.
I would of thought it makes no difference in terms of size of the wheel, but sometime laws are weird.

The front tyres/wheels can be a different size to the back, but the tyre size on each side of an axle must match to pass a UK MOT.
i.e. you could have 195/50/15 tyres fitted to the front 2 wheels and have 205/60/16 tyres on the back 2 wheels, but couldn't have a 195/50/15 tyre on one front wheel and a 205/60/16 tyre on the other front wheel.

It's not ideal, but I don't see any major reason why you couldn't. I would suggest it would be best to fit the larger wheels to the rear, but use the same width tyres all round.

big on the front. Think about it a high power car has bigger wheels on whatever axle is driving. Big on front=more traction.
Small in the front. With all things being equal you want to keep weight off the front as much as possible. The smaller wheel means less rotational weight which equates to better wheel HP. Also, the 16x7 would be better suited to the rears as the tyre contact would be slightly larger in the rear and would improve handling.
newtons law mate. Try spinning a golf ball and then a soccer ball. It takes a lot more energy to spin a soccer ball than a golf ball. Less energy spent to rotate a tyre means more energy it has to the road.

Running two wheel sizes isn't an issue, tire size is. Make sure you end up with very similar rolling circumferences via a lower profile tire on the 16's. If your car is ABS it will go MENTAL if you have a large difference in wheel speed front to rear. Found that out the hard way at the drag strip well into 3 figures. Thank goodness for handbrakes.

Just because you have bigger wheels doesnt mean you have more traction :homer:
Damm just because you have a wider tyre does not mean you will have more traction and contact patch that a smaller width tyre.
