These are the wheels that I'm planning on putting on my FC eventually. On the one site that I got the picture from, it's got a table with all of the fitments and offsets for most cars. I just want to make sure that the ones they have for the FC are right.

Front 17 x 8.0 with a +37 offset (215/45-17 tires)
Back 17 x 9.0 with a +37 offset (235/45-17 tires)

Here's the chart that they have for Mazda cars:

Well,I'll give the changes based on the stock 16" x 7" +40 offset.
The front will be @ 3/8" closer to the strut, tire will be close if not hit. The outside will be @ 5/8" closer to the fender.
The rear will be in @ 7/8" more, and out 1 1/8" more.
The front tires will be @ 1/4" lower, and the rears will be @ 1/2" higher. The difference in height would be @ 3/4" front and rear.
I know tire/wheel sizes have been discussed previously. I would search to see what sizes/offset will clear the front suspension.
Hope this helps.

 

So are you saying that they wouldn't fit? What would have to be done to make them fit?

 

Above was a response from "Ted".

 

Okay... so then they wouldn't... what would have to be done to make them work with the car...?

 

If they do present a slight problem, a thin spacer would bring them away from the suspension.

 

It's too tight up front.


-Ted

 

How tight is too tight...? Would a spacer like Turbonut said work?

 

At least 5mm or about 1/4".
SSR SP-1 "Professors" - big bucks!


-Ted

 

So it's about a 1/4" too tight up front... would a spacer fix that?

And yes, they're expensive *** wheels...that's why I'll be saving for quite a while. But I love those wheels, and I'm going to get them, even if it takes a long time.

Baller wheels for a big baller...

 

do they offer a different offset you can use for the front? you need to push them out just a bit, the offset is very close to stock but you are adding wheel/tire width significantly so the offset needs to be compensated. a small spacer will work, just make sure you have enough thread engagement on the lugs...worst case is you need a small spacer and longer lugs.

 

Spacer will work, but watch the stud thread engagement - it's going to be at the limit.


-Ted

 

They don't offer any other offset unless I get the 16's, and I really don't want the 16's. With a single spacer I would still be safe to just drive around regularly correct? There's not going to be any chances of my wheels popping off the stud just driving down the road will there?

 

Make sure the lug nuts go on at least 5-6 times.
If not, you're going to have to get longer studs.


-Ted

 

Okay.

So if I do need to get longer lugs then... where would I have to go to get these? How much do you think they would cost? And how hard is it to put them on? I read an article in Sport Compact Car about them changing the studs on their S13, and it didn't sound all that hard, but just wondering.

You can get the ARP studs for late-GM applications.
Make sure they are 12mm x 1.5 threads - ARP only make one set for this thread pitch.

I think they are about $10 for 5 or each wheel?


-Ted

 

get 17x8 +35 and 17x9 +43, perfect FC offset

 

I find those offsets a bit too much "inside".
I prefer +25 to +30 on an 8" rim up front, and +20 to +30 on the rear with 9" width.


-Ted

 

Isn't there a site where it shows the offset and what rim size would fit with the size tires, w/without coil overs? This is another question that comes up every week or so. I'd sure hate to be the one spending a lot of money on rims and tires and getting the wrong offset because someone *thinks* but doesn't know but speculating . When it finally arrives, "Faawwwkk!!! It doesn't fit!!!!"

 

So for $10 per wheel, I would have longer studs, the add a spacer and the wheels would work fine?

 

oh god

 

Oops, $12.

Yep, that'll work.

Sarcasm... said it for people just like you.

 

Thanks for all the help.
