Enkei RPF1s 18x8.5 or 18x9?

:
Mazdaspeed 6 GT
If I purchased these wheels would I need the 30 offset or the 40offset?

Also They have a 18x9 with a 35 offset will that not fit the car?

I am just wondering because they are pretty light around 18 lbs the only thing Is I really wanted bronze wheels but I dont see any I like. And these are more performance oriented.
 
If you're going with performance, just do a 18x8 with 245's. The extra rim width won't really do much as far as gaining you extra space for wider tires. In theory, it'll only be extra weight. Unless you want to do 255's on a 8.5", then you'll need a higher offset.

Of course, if it's also for looks, then a 235/40/18 on the 8.5" +40 should be adequate to satisfy form and function.

K thanks.. Yea its for looks and function. I already saw the 18x8s and the have a small lip but the 18x8.5s the lip looks more defined on them.

I was worried about the offset though Also will it rub? I plan on running 235/45s/18s and possibly Autoexe Springs or Mazdaspeed coilovers possibly.
