New wheels/tires, do I have it right?

Hey all,

Looking into my new wheel purchases and I'm thinking:

18x8.5" Et 35 w/ 245/40/18
18x9.5" Et 33 or 43 w/ 275/35/18 (thinking 43 is too wide?)

The rear offset is what I can't figure out. I've seen both and they seem ok but if anyone has any input that would be great. Also if anyone could comment on tire size it would be much appreciated.

Currently running on stock suspension (stock height), will most likely be going with a ST coilover set down the line. I do not want to roll the fenders or have any rubbing issues obviously.

Thanks.

35 offset will stick out more than 43. You will be fine with the ET 35 front and rear without any rubbing.

Great thanks. I'm assuming spacers wouldn't be needed in this set up?

Yes ET 35 front and back for a conservative setup.

Also, you should really be running 235/40/18 fronts and 265/35/18 rears to maintain proper proportions.
