205/50/15 on 9.5"

thanks for the comments. Just asking 4000GT, don't jump out the window.
Let's put things in context:

I'm using 7.5" with 195/50/15 semi slicks at the front and 8" 205/50/15 kuhmo mx "normal" street tires at the rear. It was an experiment for the last autocross I participated and I liked how the car handled so it stayed.

Not seeking the ultra stretched looks, it's just that I found this enkei 9.5 rims that match exactly my big lip 8" rears, so I was thinking on putting the 8" at the front and the 9.5 at the rear (with overfenders) and use 205's all around.

So.. Let me change the question: what tire size would be the optimal if i use 9.5's at the rear without making the car to "heavy" to handle for my 4ag 20v?

your comments will be really appreciated

thanks!

here's a pic of my current setup.
