I am looking at a set of used rims, they are 17x7 with 40mm offset and 17x8 with 45mm offset. I tried looking up old threads on offsets, but couldn't find much info to help me. Could some one help me, will these fit? I do not have coilovers.

Don't get those offsets.

To elaborate a bit, those offsets (and widths) will make the wheels look sunken in and generally crappy. I'm generally not a sizing/offset nazi like some on the other 240 boards can be, but I will say that offsets that high = bad.

For an S14 i'd lean towards 17x8 front 17x9 rear, and around +25 or lower offset.

Don't quote me on this though, I'm certainly not an expert in the wheel sizing department :)

On this forum, no one that I can think of.

On other forums (zilvia, etc.) I can think of quite a few, but I won't name names :)

msaskin is right on +25 offset for the front rims especially if ur considering a big brake upgrade in teh future. On the back +35 offset and up is the way to go . 17x8 and 17x9 is good unless u got huge amount of power hehehe. :)

offset has nothing to do with brake clearance. the only thing that determines brake clearance is the design of the specific wheel.

if you get coilovers try to go lower. +20 all around should work. anything above a +25 and you'll run into some problems.

On some part ur right but still get +40 offset and above will not fit any big brake kits. I know that cuz my friend has a s13 and change rims a cuople of times.. due to change of brake from stock to z32 then to brembo GT brake.

Design of a wheels is also a factor thats why there is only a few wheels that is available with offset options.:)

what? that just comfused the hell out of me. there are thousands of wheels with "offset options" just not cheap honda wheels. offset has NOTHING to do with brake clearance. my 0 offset wont clear anthing other than Q45's (maybe) but stock 15x6 +40 wheels will clear Z32's fine. clearance is determined by the desing of the spokes, not the offset.

We'll gets what we have to buy 3 exact same rims with different offset just to clear those brakes. Cuz we love the design of the rims so much, don't want another kind of rims.So how many rims u have bought to satisfy ur beautiful mind.

what is offset? all i know is that my wheels say "offset: 0" on the back, and i used to have wheels that said "offset:+20" and before that +42... yes i understand offset.

either your english is terrible, or im just retarded, because "We'll gets what we have to buy" makes no sense to me.

if the same wheel in a different offset fits differently, its because as the offset was changed, the design of the spoke was changed as well. if you have 2 wheels with the EXACT same spoke design, offset will be irrelevant in their fitting/not fitting over Z32's.

That is wrong. If you have two wheels with identical spoke design AND width but different offsets, it's totally possible for one to clear Z32's and one not to.

Do a search around on just what offset is and it'll make sense.

ok, let me reword. if the whole spoke/face where the wheels touches the hub is exactly the same, as in a lower offset just moves the whole center in, increasing the lip the same amount as the offset is decreased, the brake clearance will not be changed.

if the offset is lowered by effectly machining spacers onto the hub portion (lip stays the same, the mounting surface just moves back) then the brake clearance will be changed.

Sort of. In effect, the spoke design would be changing slightly since the spokes would be more "bent" inwards, which may be enough to make it clear brakes, but I see what you're getting at.

This is correct.

Generally with a wider wheel and lower offset (or same width and lower offset) the spoke pattern/design remains the same, and the lip on the outside of the spokes is increased. This is similar to the first situation you described.

Wide lip wheels are design to be wide lip. When changing example decreasing offset, lips dont increase. I don't know any wheels design that when u decrease a offset the whole spoke design follows the change resulting for the lips to increase. If u give me a brand and model wheel that do that i would consider ur point. IF that happened this whole offset thing will be very confusing. The only way u can tell if the wheel fit the car with or without bigbrakes kit will be by trial and error. :)

any mesh wheel. the offset determines the lip.

SSR reverse, full reverse.Enkei 92's

the lower the offset, the larger the lip. no mesh wheels clear z32's, no matter what the offset.

"the spoke design would be changing slightly since the spokes would be more "bent" inwards"

i said without changing the spoke desing. youre describing what FN01RC's do, as the offset decreases the spokes curve inward. im saying just sliding the entire spoke section towards the inside of the wheel. youre saying that the changing spoke design is making them clear, not the offset change, exactly what ive been saying all along.

Gotcha. It's still tricky to think about, but it's making more sense :)

I guess it all depends on the wheel choice...when it comes down to it clearance is really a tricky subject...at best it's guess & check unless you can find someone with your setup to see.
