Spacers here... what's my new offset?
Okay fellas - I just got spacers in to convert my 110 to 114.3 (thanks Kim!). I just need to know what offset wheels I should be looking at now.
I can measure the spacers if you need to get it accurate. I'm basically just curious if I should be shipping for 'Honda' +40mm offset wheels now or what?
I found a few that I like a lot... but they are all 17". Are 17's too big to fit under there or no? I have a pic on my desktop of a silver FB with photo-shopped 17's on it that look AMAZING. I'd like to go with that look if they can fit. Thanks for the assist guys.

Lol, sorry mang... they look good though! I'm also wondering if I'll need a center ring for them so the wheels dont shimmy.
BTW, 5 litre eater - I ALWAYS wanted my liscense plate to say '5ltretr' since all my buddies are into Mustangs.

The spacers are 1 1/4" thick, or 31.75 millimeters. I think I remember reading that we are supposed to be using a 20mm offset now. So, do I add the 31mm to make a total of 51mm? That's impossible to find.

Offset also has to include the wheel width or else it makes no sense. Seeing as it is figured from an immaginary center point on the rim then it is + or - in mm.
Stock 110 mm rims are +17 on a 5.5" rim, or 137.5 mm whell width divided by 2 is 68.75 to the center, then add +17 for stock offset. this is 85.75 or about 3.5 backspacing. That is the figure you should be using as your baseline then add your spacers and Bob's your uncle. approximately 136.75 backspacing.
Remember wider wheels will need to be worked out carefully taking in your fender position.
ie: A 7" wheel width is 175 mm, divide by 2 is 87.5 mm plus 40 mm offset is 127.5 mm backspacing before your spacers.

Great info man! To understand fully: If I want to run a 7.5" wide rear rim, I need to get my overall offset/backspacing spot-on so that I dont rub.
That said, what amount of backspacing would bring the wheel flush to the fender? There has to be a genereal measurement, right? That would be from the hub face to the edge of the fender, yes?
A 7.5" width is 190.5mm / 2 = 95.25mm. Add 40mm offset of the wheels I want, and I have 135.25. On top of that, I need to add my wheel spacers at 31.75mm for a total of 167mm or 6.6" of backspacing. Is that right?
If so, 6.6" backspacing would stick out beyond my wheelwells Ah-la Durango Mexico style? To correct that, I need to lower the offset on my rims to 28-32 (depending on the backspacing measurement you might provide to get them flush with the fenders) OR buy rims that are not as wide, saving myself an extra 7.75mm (.3")?

The problem with 20 year old fenders is they tend to vary a little due to wear, rust, repairs, parking etc, you'll need to measure your own car yourself. Also are you planning on rolling the lip.
The math you have done looks right, and yes the measurement is from the hub face to the fender lip, but remember to make sure the inside edge also can still turn to lock and clear the suspension.
You can go inboard about 12 mm of the stock 110 wheels safely but check this yourself manually. You may find you can go further.

Thanks a lot Aaron. Are you on spacers too? If so, what is the correct offset range for you? I think I'm still a bit confused actually.
I measured a 2 1/4" backspacing from the face of my spacer to the edge of the fender.
That means that to run a 7.5" wide wheel, I need to run an offset of ________ to be flush with my fender? The math is really giving me a headache now. Aussie, if you can help, I'd love it.

Well logic is telling me that 2.25" or 56.25 mm, removed from the total wheel width of 187.5 mm for 7.5" leaves a total of 131.25 mm or 5.25" backspacing on your choice of width. 2.25" plus 5.25" is 7.5". Now to change this to offset, zero offset is 93.75 mm, plus your 31 mm spacers your total is 124.75, meaning you need a wheel with an offset around 6.5 mm to reach to 131.25 mm ideal.
Note if you took your measurement to the outside of the fender lip you will have tires to this point, hopefully you took the measurements to the inside edge only.
Again I stress check many times before purchasing, math is only as accurate as the measurements and other unseen factors.

I run 205/50's on 15 inch Konig Monsoons
they rub during hard cornering
not to mention small popping sounds when you have the steering wheel at it's stop
none of this occurs when I have the stock 14's on
so with 17's do make sure as mentioned to have the measurements down
my suspension is stock btw..not lowered here
oem 14's< 15's 16's 17's much greater weight

93.75 is zero offset, add 31 mm to backspacing for the spacers, now the backspacing is 124.75 mm, this leaves 62.75 mm or about 2.5" on the outside of the hub. This is a wheel with offset of 31 mm, negating the spacers exactly.
Sorry about the Fubar....lol, that 6.5 has been bothering me all day....

Thanks for the tip Scott - and BTW, I'm not lowered yet, but I will be by the time I get the rims settled on.
Thanks for the help guys, I REALLY appreciate it.
