On King Motorsports' web site, it says that the Mugen MF-10s come in +43 and +50 offset, which is better for the ITR? What difference does it make?

 

50mm offset is the same as stock offset. You can use up to a 225/45 tire with this rim type.

43mm offset pushes the rim "out" by 7 mm relative to the 50mm and makes the tires stick out more - but you can only run a 215 width tire.

I'm not sure if there is a huge track width difference between the two.

You can also think of it like this: A 43 mm offset rim is like a 50mm offset rim with a 7mm hub spacer.

Mugen rims

 

Don't mind this incorrect post...please read my other reply

Stock 15X6
+50mm

Mugen MF-10's 16X7
+43mm
+50mm

The +43mm offset pushes the tires farther out of the wheel well, the outside lip of the rim will be 1.25" farther out of the wheel well than the stock rims, gives you a +14mm(total) larger trac, and (correct me if I'm wrong)also places more weight on the inside of the tires, gives you a slight increase in negative camber...more for track use, I own a pair of these.

+50mm offset keeps the rim relatively inside the wheel wells, but from the stock rim the rim will stick out of the wheel well 1" farther. More for street driven applications.

Hey...if I'm wrong, someone correct me, but this is the information that I have accumulated over the last year and believe to be correct.

Are you sure on the 1.25" further extension?

I would think that it would be the 7mm (.2756") + .5" (1/2 the extra tire width) for a total of .7756" further out per side...

 

...now I understand more about offset: http://www.tirerack.com/wheels/tech/offset.htm

Looks like I had a few things off...

The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. The offset can be one of three types.

whats the offset of the jdm itr 16" rims?

 

I don't see how the smaller offset pushes the rim out. I would think if there was a larger offest it would mean the middle of the rim was closer to the middle of the car .. someone edumucate me

 

Look at the drawing a few post up. The higher the offset the more you can push the wheel inside the well and the smaller the offset the less you can push it in.

 

So for a street setup +50 would be ideal? I don't want the wheel to be wide enough that it sticks out? Will I be happy with a +50 MF-10 if I decide to go to the track?

 

...why if you're selling the car?

 

50+ offset will be more than enough.

 

Would 215/45 on a 16x7.5 tire rub?

 

What offset?

 

The extra 7mm would help on the track. Same idea as one would use wider tires in that matter.

But usually the concern is more towards the clearance issue...ie. if you are planning to use a larger brake caliper, then the +43 offset MIGHT clear the caliper without the use of spacers.

 

You have to consider the measurement is relative to the mounting face of the hub.

 

Not sure, Kosei K1 16" is the wheel.... I'll see if I can find it.

 

It also depends on the width of the rim.

 

with +50mm offset you can always use spacers

Here, I know it's another board...but I did a huge post on offset...explanation's there, pros and cons of different offsets, etc, etc

Hope that helps.

Sticking out. And +40 should work fine.
