The Official FC Wheel Fitment Thread
FRONT WHEEL (To show lowering)
DISTANCE FRONT WHEEL HAS LEFT
REAR WHEEL
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.

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.

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.

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.

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.

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.
