DISTANCE REAR WHEEL HAS LEFT

Through my crude measuring (via a 6 inch steel rule and a popsicle stick) I have determined that my lowered car (of unknown inches) by the previous owner has about 15mm in the front and 35mm in the rear (rough estimates) to the outside of the car's body limits. This is not taking into consideration tire size at all. I think the front tires are already barely rubbing the fender liner.

I am on 205/60s on the stock 16x7 +40.

Remember, I'm going for 17x8s all around.

So what can we determine from this? Am I doing something wrong? I can't see how a +35 in the front or rear would fit...

First, there’s no need to hurt your brain so hard, as wheel fitment has but been all tried out and there are solid guidelines to follow. There’s been a TON of people who have done the work for you. 17X8 35 225/45/17 fit fine period. Now, to ease your brain of your math. Using what you stated, stock is 16X7 40mm with a 205 section tire. A 17X8 35mm offset will be 5mm out farther due to offset and another 12.7mm out farther due to the wheel being another inch wider (half an inch each side, 12.7mm is 1/2"). Now you have a total of 17.7mm more wheel/tire (225 is only 1 inch wider then the stock 205) sticking out which is only 2.7mm (tiny amount) off from your CRUDE measurements. Now, another factor your missing is the fact that our wheels do not travel straight up and down, there is a camber curve, meaning the wheels gain negative camber while it is compressed tilting the wheels inward thereby gaining space from the outer tire to fender. Yes, even McPherson struts have camber gain within its stroke.

In summery, YES 17X8 35mm offset and 225/45/17 wheels fit fine on MOST Fc's. Worse case you pinch or roll the fender a tad or if you have strut contact get a tiny spacer either problem is rare with this fitment.

That seems to work for the rears, but for the front I come dangerously close to the inner fender. Are you sure I wont rub? Thanks for you help, I guess I did alright for a popsicle stick!!

do you know what kind of springs you have?

Nope. Any way to tell? They are magentaishpurple in color.

It's all here:

You can go to a 225/45/17 on a 17x8 25mm offset, 30mm is about perfect and that's what I use and have never rubbed on anything.

Some lowering springs (Tein, Tanabe) offer LESS inside clearance, so a 17x8 35 with a 225 probably won't fit, as it's really close to the suspension on a stock car.

You sure?
205 / 55 / 16 is the stock tire size.
If you are running 205 / 60 / 16, it's significantly taller than stock.
That would explain the rubbing...

It looks that way from the pictures, too tall tires.

+150
17x8, 25-35 offset, with 225/45/17. its by far the safest choice. after you have that mounted you can check your clearances, and maybe get wider tires next time. the offset is just fine. F and R.

18x9.5 +35 all around..88 TII..stock suspension..would this fit my FC with rolled fenders? thanks!

I'm positive. The tool who had the car before me mustv'e got a deal or something. Thank you for clearing that up Ted, good to hear I'll gain some room.

Not up front...
You need like a 1" spacer to clear the insides.
Rears are fine.


-Ted

I thought a 9.5 +24 fits up front on stock suspension so he would only need a 10mm spacer?


right? didnt the mustang cobra 17x9.5 wheels fit for someone in +24 offset up front?

?

the stang wheels are 17x9 +24. 9.5 on the same offset is pushing it. it will probably fit with a 245, but i couldnt guarentee it.

the worst fitment ever...

let the hating begin....

i fucking love it saw the thread on ZT, fucking keep hurting them justin, hahhah

btw i got the fenders, thanks bro.

Seriously, you guys actually dig that fitmit?

~Mike...........

Yes, yes we do.

way beyond factory mazda specs.... disgusting. and way unsafe.

that is the DEFINITION OF FITMENT

Oh my, where to start...

Hit the smallest bump and the wheels will hit the fenders, turn the wheel much at all and the tires will rub on the fenders, those wheels are way bigger and heavier than is needed to fit those tires, making the acceleration, braking, handling and ride quality all much worse, plus the tires don't actually fit on the wheels.

That's the definition of NON-FITTMENT.

ooookkkkk...
its a show/drift car. you know he isnt driving like that
calm down~

my oh my!


hold the phone!


Justin! Thats actually detrimental! Cut it out!

Hahahahahaha, that car looks so useless.

What does it do, sit there looking broken?

Get 275s all the way around on it, put some power in it and drift it that way!

Well if it's a car that'll never move, why put it in here as an exaple of "fittment"? It was never said that it'll never move under it's own power, so I thought that some of the flaws of that "fittment" should be pointed out.

This thread is for cars that work.
