Well, i want some new rims... maybe someone can help me with some questions...

1 - How much will a 1" larger rim (low profiles, 40 or 45s) effect performance? I know smaller diameters spin faster, but im not sure how 1" will effect the cobalt..

2 - Konig Hotswaps - Im going to do some searching, but if anyone likes to post pics of there crap, i wanna see! Any reviews would be cool too while i look around the forums.

3 - Lowering springs - How does the fitment of the stock 18s with lowering springs look? Some cars, with smaller tires that are lowered, look kinda funny... Not sure if the cobalt has this look or not, which is why i may want the 19s with the lowering springs...

Any ideas or pictures would be awesome... Mind you, i am doing searching as well, but new updated information is always welcome..

And above all... how much does the ride change with larger rims / lowering springs / both?
