The FC Fitment guide is getting JUST TOO LONG....

I've been compiling a list for some time now of what will fit on an FC...

SO.. IF you got wheels.. PM me with what they are, the size and offset, the tires size and brand, if you have completely stock suspension, or WHATEVER you did to the car to get the wheels to fit (wide fenders, Spacers, Coilovers Etc)

Include comments about how they fit as well, like are they flush, is the speedo off, how close are they to the suspension, do the dust caps fit... (mine didn't!!!!) Etc...

I'll get it compiled and post it so that people can just rummage through it, should cut down on the mucking about and all the guess work cause if someone else is running it, then, you know it will fit!!

ppl should post you pics of the wheel VS fender.

So ppl will see if they like or not the offset

Not looking for another big assed thread..... Just lookin for a list with comments....

Stock fenders and rear suspension.
Tokico blues up front.

17x8 TSW Hockeheim R's
235x40x17 with 5mm spacer up front(about 5 mm of spacing from spring)
245x40x17 in back.

the front tire aspect isn't stock but it is on the rear which reads the speedo

Any post without offsets will be useless.

18x7.5" Volk LE37T
215/40-18 BFG KDW tires
+48 offset
Clears my KYB AGX/Eibach suspension with ST sways by a mile.

Centercaps fit on the rear, but not the front because the stock front wheel dust covers stick out too far for the centercaps.

Speedometer is off, but not by much...When it says 60, I'm really doing about 63.

I bought these wheels for a different car, or else I'd be rolling 17X8.5 or 9" +35 wheels...there's plenty of room for more width under my fenders.

I realize that an 18" wheel with a +48 offset should be "iffy", but they really do fit fine.

Dude.. OFFSETS

YF19

Advan Battle Version Sierra II's
F: 17x8+35 - 225/45/17
R: 17x8+35 - 225/45/17

Also have:
- stock struts
- eibach springs
- 5mm spacers

Notes:
I'm using 5mm spacers because since the tires are wider than the wheel itself; and it expands and flex and all that, it's a little close to hardware to my liking. I just used a spacer to give it a little more breathing room. On a hard compression, i did scrape the front fender lip. In hind sight, I should remove the front spacers.

Riax Seca 16x7

42mm offset

205/55/16 tire, it all fits perfectly. (I'll have to see whats going on with I do a suspension though !)

Ronald E. Jacques

Mine is stock body and suspension except for sway bars.

Konig Incident wheels
16x7+40 offset F+R
205 55r16 front tire
225 50r16 rear tire

TitosToy

anyone here with some comparison with the 4-lug pattern or will the fitment be the same as the 5-lugs?

Madrx7racer

how do I find the offset ?? mine are discontinued wheels from ADR

RETed

It's either stamped, etched, or embossed on the inside (usually).
Inspect all parts of the rim to see if you can find some numbers.
If not, they are a piece of ****.

You can also:
Lay the wheels face down on a protected surface. Lay a level or other straight item like a 2x4 or something across the back of the wheel from lip to lip. Measure from that board to the mating surface of the wheel. Thats your offset.
Offset is one of those counter-intuitive things. The more offset, the farther the hub of the wheel is from the back of the rim, which moves the tire INWARDS. So if your tires rub on your fenders, they need more offset. If they rub on the struts, they need less offset.

RETed

I'd just like to warn people, that this method is not a true measure of offset.
With different lip profiles, you could be off as much as 5mm on the offset!
What the above describes is a true measurement of "backspacing".
Backspacing and offset are two different ways of describing the same thing - the position of the mounting hub relative to the wheel dimension.


-Ted

Ronald E. Jacques

Thanks Ted for that clarification. I was only suggesting that method in the case where there is no other way of determining offset, as stated by Madrx7racer. Its better than nothing!

RETed

No, no problem.
I find the idea of not compensating for the lip profile kinda dumb in the first place.

I mean what if you run into a rim with no indication of true offset???
I guess you can always measure backspacing and tell the next owner that, but that's a stupid alternative. :P
Yeah, "offset" gets real confusing sometimes!

All your high quality wheels have the offset engraved, punched, or embossed on the wheels.
If is your rim doesn't have this, throw them away?

Measuring offset is simple. First do the above meathod to find backspacing (straight edge across the back of rim lips, then measure down to hub mating surface). Now measure the rim width. Just a side note, rim width and height will alway be higher and wider then the size of the wheel. EX: a 17X8" wheel will most likely be over 18" in dia and at least 9" wide overall from lip to lip. Wheel sizes are rated were the bead of the tire seats. OK, back to offsets. Take your over all width, divided by two and subtract that from the back spacing measurement you took. Now multiply that by 25.4 to convert to mm.

EXAMPLE:

17X8" wheel. You measure 9" wide (outer edge to outer edge/lip to lip) and you also measured a 5.75" backspacing (backside lip to were it mates with hub).
9" (total rim width) divided by 2 = 4.5
5.75" (back spacing) subtract 4.5" = 1.25"
1.25" X 25.4 = 31.75mm
Your offset is +31.75mm

If half your overall rim width is larger then the back spacing then your back spacing will be negative. If half of overall rim width equals backspacing then you have a 0 offset.

Using backset, instead of offset, is usually the easiest way to determine wheel fitment

YearsOfDecay

Fitment will be the same regarless of lug pattern

jon88se

For the 4 luggers out there who want some aggressive looking wheels, any setup that fits an S13 will bolt onto an RX-7. Same bolt pattern/offset...
