google a good tire size calculator or find one referenced here somewhere and find the best match for what you are trying to do. If you are going for better performance than the lower profile you picked for the fronts would be the way to go, but the 255/40 would prolly be a better match for the rear with a slightly smaller overall diameter as well. But all in all the difference may be small enough not to matter, either way. The calculator would let you know for sure.

The calculator will tell you what is the diameter of your current tire and let you know what the diameter the tire you are interested in. Here are a couple I like:
http://www.4lo.com/4LoCalc.htm
http://www.miata.net/garage/tirecalc.
I think if you try them out you'll see what I mean. Lower performance means shorter sidewall. Shorter is basically stiffer so it deflects less than a tall sidewall when cornering, so shorter is more direct handling, more performance. Think low profile = rubber band, and high profile = monster truck tire. Shorter sidewall also means you feel the bumps more tho, so there is a penalty.
I hope this helps, and the half bottle of wine I just had with my turkey doesnt interfere with the reply
Cheers!

^ I agree, I would not recommend those sizes.
When I picked up my 350Z wheels they had 225/45 (OE for Z) on them.
Having the lower profile on the front sucked big time!!
With your rear selection it will be even worse than what I experienced.
FWIW, this the calculator I like.
It charts all the variables at once.

On the front, just one comment on the size you highlighted. The load bearing index is lower than OEM. Along with the lower profile, it is highly possible that the tire will get damaged with any significant hit. (I learned this the hard way in the past, always wondered by my tires would get sidewall bulges when going over any pothole or dip at any significant rate of speed).
How about 245/45 for the fronts?
