Default understanding offsets....

I'm a bit confused....

So i have 15x7's et 40mm. And they are kind close to the edge of the fender, but not much.

Now konig makes a RWD, deep dish Rewind that is et 0mm and 15x7. 40mm is about 1.5 inches. So would switching over to this version just mean that they would stick out 1.5 inches away from the car? 1.5 inches really isn that big of a deal, and would really only add a small bit of poke to the car.

The reason i ask was that i have seen some nice 20mm and 25mm wheels, and i kinda want a bit of the euro-poke look. Would these work. Could i even get away with the 0mm konigs with the huge lip?

the deep dish konigs:

ZERO OFFSET
The hub mounting surface is even with the centerline of the wheel.

NEGATIVE OFFSET
If the hub mounting surface is on the brake side of the center line of the wheel, it is considered a negative offset or "deep dish".

POSITIVE OFFSET
The hub mounting surface is on the street side (the side you see) of the center line of the wheel. Positive offset wheels are generally found on front wheel drive cars and newer rear drive cars.

The offset of a wheel is what locates the tire and wheel assembly in relation to the suspension. More specifically, it is the measured distance between the hub mounting surface and the center line of the wheel.

yah....i know what an offset is....i'm just a bit confused as to why i couldnt throw some 20mm instead of 40mm cause the 20mm is tiny.

For example:

15x8 et20

middle line is at 4 inches. With the offset, the hub is at 4.78 inches.

15x7 et40 (my current wheel)

middle line is at 3.5 inches. With the offset, the hub is at about 5 inches.

15x7 et0 (konig rewind RWD)

middle line is at 3.5 inches. With the offset, the hub is at 3.5 inches.


did i get that right so far? If so....an et20 on a 15x8 would actually have a skinnier track than my current wheels. So i could go as low as probably 15 or so...right? And if you keep the 7 width...but lower the ET substantially, you only get about 1.5 inches of track on both sides....whcih i think would be totally fine aesthetically.

I know a lot of this would cause rubbing with bigger wheels....but with low-pros on 15s it really would be that big of an issue.

You could certainly try, but you're probably gonna rub like crazy. Moving the hub mounting face closer to the centerline pushes the rim further out. My 17x7 ET 37 OZ Superleggeras will rub with 215/45-17 tires, so I couldn't imagine pushing them out another 17mm. That would probably be pretty dangerous, and could quite possibly tear off your fender trim if you were to hit a big bump, unless you plan on using seriously high spring rates to keep suspension stroke to a minimum.

Oh, and also--bump steer would be unbearable. One little bump on one side of the car would rip the steering wheel out of your hand! It'd be very nervous at high speeds, as well.

ahhhh i knew i was forgetting something. I remember having that problem when running negative offsets on my RC cars in races...hahaha

I would probably rub with the 15x7 et0's.....but what about the 15x8 et20 which has a skinnier track. Are there any issues there?

man you're confusing me I asked my wheel whore buddy your question, waiting for him to ge back to me, i don't wanna say the wrong thing.


i think 15x8 et20 will poke quite a bit, since our stock offset is like et48

15x7 et30 would be pokeage, but perfect as well as 15x8 et35. anything lower would go to far outside. unless you run stretched rubber.

so i think the et0 will be crazy poke

hahah yah the et0 was an extreme example to make the point. I was more thinking et25-35.

Maybe flame suit on.....but what are opinions on 10mm spacers?

from my buddy:
yes, they would poke out 40mm more, but the back of the hub might not allow for brake clearance, so you may need spacers on top of that

10mm spacer would work on a wheel with a higher offset to push them out closer to the fender, but if you already have a wheel at et25 or et35, you won't need spacers. I personally think a et38 would sit perfect. I'd use spacers only on wheels with et40 or higher (or unless they didn't clear the brakes)

Hm... y'know, maybe you could go for a more aggressive offset in a 15" or 16" if you went to a tire that was on the narrow side. For example, a 15x7.5 with a 195 section width tire. That way, the sidewalls would pull in quite a bit, possibly keeping it from rubbing.

hey ivan, what would you think of me adding 10mm spacers to my et40's. They wont rub as my tires are tiny....im realy just wondering about what you think of spacers. I would remove them for track days....but what about just for the street?
