2010 GS wheels spacers
I have a 2010 GS and I would like to make the wheels more flush with the fenders. I know this would require a wheel spacer on each wheel to push them out and make them more flush. But has anyone done it? If so, what size spacers were used? Could someone calculate this for me? Previous cars I have had members who are experience with offsets and such calcualte this. I have no such knowledge thou.

How GM with all their resources and engineers has set up the wheel offset on GS is optimum. You will think it is perfect then you will hit that huge pot hole at speed and bam! You may end up with reduced suspension travel, tire rub, at worst cracked fenders. Spacers also put extra stress on wheel bearings, front or rear. Naturally this will also change the handling dynamics to the detriment of the design.

I personally HATE using spacers. To address what you are asking why dont you just get 345s for your rears. I did this on my old Z and it made a huge difference to me and I got a lot of good feedback and compliments. Its not cheap though. I dont have any pics with 345s in back but can someone post pics of 325s and 345s. It looks much better.

JCBARR25- I would be curious to know what tire sizes you are currently running.
I think the factory offset is pretty good, what I do see is guys buy lower profile tires than stock, you lose the sidewall height and it makes the whole wheel tire combo look off to me.
Lowering the car can also get rid of the gap you are looking at.
Man I wish they made air ride for a C6 so I could have the best of both worlds

If you look close the old 325's are on the chrome GS wheels. The new 345's tires are on the black spyder wheels.
If my understanding of tires are correct, the 345's are 20 mm wider which is about .788 inches wider.

Even while using the same wheel?? I thought that as long as the wheel was the same width, it would not change depsite tires

IMO: I would not do it. I saw it done once and the person made a fast turn at an intersection, hit a bump, and tore up both front fenders 
Flush was not a good choice with the wheels turned outward.

If you drive the car regularly, having the tire flush with the fender lip is going to cause rubbing, and possibly fender damage. If it's a show car or very seldom driven normally, you might get away with it. Spacers will add stress to your wheel bearings, and alter your suspension geometry and alignment as well, so many people who drive their car enthusiastically will avoid spacers at all costs. IMO, spacers are for show cars or display vehicles.
And yes, a wider tire will protrude more, even on the same size rim. The sidewall bulges out past the rim.

You are going to do what you want to do, but these folks here that are telling [not] to put spacers on you GS are not giving you bad info. They are trying to prevent you from making a mistake.
As others have told you ... Lower your GS slightly with the adjustment bolts, and you will see that you don't need any silly spacers behind your wheels.
Your car ... Do what you want

As Turbo6GTA said, expand your search to include all wide-body cars. If memory serves, some people on here have achieved their desired results on wide-bodies with 1/4" spacers.
I agree that GM sets the wheels on these cars too far inboard which results in a sunken in look, especially on the narrow body cars. Yes, you want to avoid a "hella-flush" setup with lowered suspension if you do not want to rub when actually driving your car, but there is still room to play with on all C6s (and C7s IMO).
For reference on how GM addresses this issue vs other manufacturers, check out Porsche, Audi and even the new Ford GT350. They all locate their wheels further out for more of a flush look. Lots of people like it, some don't, some don't even notice.

Well I am not going for a hellaflush look. Just some better looking stance. I don't track the car so how I am not gonna be putting the car thru stress or hrs of hard driving. I appreciate the opinion on not doing it but this is the same with any other mod. GM didn't do LT headers on the car, yet lots of ppl do it. GM didn't do tons of mods ppl do. I just can't justify buying new wheels when I actually like this set of wheels. I just want a more aggressive offset look. Longer studs and spacers has worked for many ppl not just in corvettes but other cars. There is always risk with any mod.
Looking for GS wheels pics mainly to see how it would look. Idk if the Z06 wheels are similar concave as the GS.
