well on that note,
it is the opinions of many here that wheels like what you posted earlier are not well suited for the kind of cars we drive. I for one probably acted a little hastily in picking up the flame thrower instead of helping you, my appologies.
I understand that it is your car and money and you can do with it as you please, but you may want to go another direction when looking for wheels.
18x10 is a fair size out back. if you go much larger than that width wise you will most likely need to roll the fenders.
19's will fit aswell but if you eventually start making any power you will tend to find traction in short supply.
