I have a Fit Base with 15" steel wheels. I was wonderin if there is an easy way to get a list of other brand cars, that have the same bolt pattern, and offset, etc.
Either 15" or 16"
I heard that some Miatas have wheels that would fit. There must be others.

 

Mini.

You're talking about OEM wheels only? There's lots that are 4x100 hub pattern, you have to watch out for hub bore, which needs to be 56.1 or greater or you're going to have to run spacers that clear the hub lip. You have to especially be careful with Toyota and Mazda, some of the 4x100 wheels are 54.1 hub (INCLUDING MIATA) and will require a spacer to clear the hub or drill out the wheel hub to 56.1.

Here is an exhaustive list of OEM hub specs for pretty much every car up to 2008, you can probably assume that hub sizes by manufacturer haven't changed a ton if the model line is continued and hasn't had significant changes. ALWAYS MEASURE BORE AND LUG SPACING BEFORE PURCHASE.

^ Beat me to it...

And yea, for no hassle/no fuss the only other OEM manufacturer that has "direct fit" stuff is Mini wheels. They come in a dizzying variety of styles too and are usually cheap on mini forums.

 

If you are ok with 15inchers, look into civic SI 7 spoke alloys I ran mine on our Fit for a few weeks, i thought it looked pretty classy. the off set is slightly out more but didnt have any problems with that. The tires i had from my civic were too small for our 09 Fit sport but i think if you have a gen 1 Fit the tire od is smaller than the second gen. stuff.

 

Classy you say? Not bad for $800 shipped for American Made wheels....

mmmmm...
