    Some of you might think this is a no brainier, I did, when I started thinking about my wheel upgrade 20's all around for me especially since that's what it came with.
    - Hear we go, from my reading one thing you do to improve handling / breaking is to reduce un-sprung weight, (the weight that is not supported by the suspension). Since there are so few performance parts for the SHO the easiest way to do this is light weight wheels. My very quick and completely non scientific research tells me in general 19 inch wheels are a few pounds lighter, then the exact same wheel in a 20 inch. there are also a lot more styles to choose from and seem to be a few dollars cheaper.
    - My understanding is 19 or 20 will both work with all the SHO break packages and I am a substance over style kind of guy so can anyone tell me a reason NOT to use the lighter 19 inch wheels, or some reason I should use the 20's. This is a long way off but I like to plan ahead. As always thank in advance for all your advice.

    From my experience the 19's are less available now that was a couple of years ago so maybe the market is better now. I personally think the 20" fill in the wheel wells better without being overly obtrusive. A lot of styles during my research some weren't available in 19 so selection is limited. I am talking about the wheels themselves not the tires. Check TireRack.com they have a vehicle wheel tire finder that even has a link to put vehicle with color and it will give a visual of how a wheel pattern would look....the tire on that link is generic but you can get a decent view of how wheels would look.

    The numbers have shifted, on Tire Rack there are 100 - 19 inch wheels and 24 - 20 inch wheels, not one of the 20 inch wheels is under 22 pounds. I have been using Tire Rack so far its the only one I have found that includes weight of the wheels. Now there are other light weight wheels out there but some of those are very expensive, I am not spending 6K on wheels.

    Check the weight on the tires also. Going smaller on a wheel will force you into a bigger tire. The weight might offset, then you to spend more money on 19" tires. Try some springs if you want better handling or better yet, some Megan coil overs. Don't let tire rack consume all of your time. There are all of other places that sell wheels with the 5 x 114.3 pattern. Use tire rack as a reference.

    -Very good point about the tires that is the different perspective I was looking for, not sure if they have tire weight listed but I will look.
    Megan's are not for me, way more adjustment then I need or want to deal with, I am going to do springs before wheels most likely. That being said the stock rims are ugly and very heavy, if I could get 40 pounds of un-spring weight off the rotating assembly that would do a lot of good. I try to look at other Tire sites but Tire Rack is the only one that has the weight as a search parameter an makes it easy to search. I was in a tire shop the the other day and asked "How much do they weigh" he shrugged and said "I don't know, Not much".

    When you go to 19s you will need more sidewall. More sidewall equals more flex. You may have a better ride but it may feel looser in the corners or making abrupt steering inputs.

    Less sidewall less flex but you will have a harsher ride due to the tire having less room to flex.

    I wouldn't say that all 19 inch wheels are going to be lighter than 20s. It depends how and what they are made with.

    Two people can be 6 foot tall. One 300 lbs the other 150. They are the same height, but built diferently.

    Very true, but I have seen the exact same style rim have as much as a 2-3 pound difference in weight. I could be wrong which is why I am asking but I think the reduction in weight is worth the increased size in sidewall. For the record I am not saying I want 19 inch wheels but when you have a budget the selection and price range is a lot better when you include 19 inch rims.

    Get some carbon fiber rims. Those are sure to be light.

    Good advice: Thank You, and I guess it was my fault for not being clear, I am looking for an affordable rim. That was one of the reasons I was looking at 19 inch, more choices lower prices.
