Time to loose some weight?

I've been thinking about getting a new set of EC-7 wheels and shed some wheel weight, about 5 pounds per corner.

I know option A is safe, no rub. I think option 2 is about the same as what I'm currently running, just a bit wider towards the inside on the rear if my math is correct...and I think C may be pushing it on the front offset. What's your opinion?

I plan on mounting 275/40/18 all around.

My options are:

A. F:18x8.5" ET35 - 20.10 lbs, R:18x9.5" ET58 - 20.65 lbs

2. F:18x8.5" ET35 - 20.10 lbs, R:18x10" ET43 - 21.95 lbs

C. F:18x9.0" ET42 - 20.75 lbs, R:18x10" ET43 - 21.95 lbs

4. F:18x9.0" ET42 - 20.75 lbs, R:18x9.5" ET58 - 20.65 lbs

(Options 2 and C have a more concave rear wheel, which I really like)

I'm currently running:

F:19x8.5" ET45 - 26ish lbs, R:19x9.5" ET50 - 28ish lbs

Go option 4, will fit perfect on the car, don't worry about the fronts. You could do a 9.5" on a +40 and be fine.

Won't tuck too much. CTS-V rear wheels are a 9.5" wide on a +56et offset...

Do the 18's clear Brembos? It looks like you want to stay with a staggered setup right? If so then my vote would be 4.

If I had to do this I would do a 18x9.5 +43 all around with a 3mm spacer up front. Then I can do 275's on all 4 corners and able to rotate tires.

if you want to do 275s all around why not just do 9 or 9.5s all around. if you do 9 up front and 10 in the rear, or 8.5 up front and 9.5 in the rear with 275s all around, your front tires are going to look larger then the rears, and that just doesnt look right.

there are the nurburgrings, and 18x9.5 et 40mm is a perfect offset for 9.5 and 275s all around. they are 20lbs each too, and clear the brembos.
