Will this work out without any correction being done to the fender or suspension? I found tons of mention with going from 18's to 20's but nothing about a base 16 being swapped for 18's

You shouldn't have any problem.. I'm sure one of the 8th gen guys will correct me if i'm wrong but i don't think i am in this case

^He's switching Wbody Impala SS rims, so they'd have to be the same.

Yes, they typically fit, but some people have had trouble clearing the struts with the tires. It is not typical, you will probably be perfectly fine, but just an FYI.

I provided a link about issues some guys run into changing from 16 stockers to 18 stockers. I will try to find it again. NEVER an issue going from 18 stockers to 16 stockers interestingly.

That's very odd.. I'm curious as to what problems they would have.. cause you would assume GM would compensate for the larger rim with smaller side walls but who knows.

In the past a number of people have reported the tires rubbing on the strut, possibly due to the differing suspension setups between the SS and LS/LT.

Whats odd is that some have the issue, most dont. I say go for it.

my twin bro just put 18s on 2011 ls that came stock with steel 17s no problems what so ever and i must say what a difference a set of wheels make u shouldnt have any problems

Agree, because even if you are one of the unlucky, the fix is not too hard - I am still searching for the link...I have posted the link here before too. A guy named ImpalaJoe at NAIOA had the issue putting 18" LTZ rims on his 07 , and detailed the fix for it (I bought his 07 LT rims from him).

Just out of curiosity, are the LTZ/SS wheels wider than the LS/LT wheels as well? Or just taller?

Wider as well. 225 is the LT width.

That would also have an obvious impact on fitment (possibly)..

Todd, you and I are not getting much done today are we?

Hey, I found my post here which details the issues. And stickied it since it seems I have to look for it every few months.

OP, read this and it provides a synopsis of what you are looking for. You may or may not have trailing arm or strut plate or control arm issues - luck of the draw, though most have no issues. No rhyme or reason. Going from stock 18s to stock 16s is never an issue though, never.
