Hey guys, I'm interested in buying these wheels for my white sedan.
18''tenzo-r passion 5 (wheels)...bolt pattern is 4/100 & 4/114.3. How easily would these fit? Would I need spacers or any other "mumbo jumbo"?

 

SS sedan or LT Sedan?
I imagine that you have an LT, since you have the four lug rims listed, but to assume just makes an ass of u and me

 

It's a LT

 

18"s fit fine on any Cobalt. In my opinion 18"s look kinda small on our cars, even when lowered. I have 18x7.5 Enkei WDMs on my SS 2.4, and while I plan on keeping 18"s for sustained performance, i'd really love to go with a 19x8. Even with a .5" wider wheel than stock, it still wouldn't hurt to get some spacers to make it more flush with the fenders/quarter-panels....but i'm not gonna bother with it right now. I envy two of my best friends with Focus's that threw on 18x7.5 wheels and it looks perfect b/c their cars are so damn small, lol.

But you could actually go as big as a 20" wheel as long as it isn't super wide and you use the correct profile tire (30 or 35). But I say go 18" or 19" if you want to keep it a daily driver.
