This is from the FAQ about wheel offsets:

Front:

16x6.5 = +55mm (e.g. stock) [minimum of +50mm]
17x7.5 = +52mm (e.g. Mugen MF10)
18x7.5 = +50mm [minimum of +48mm]
18x7 = +48mm
18x8 = +53mm (e.g. WORK MEISTER S2R)

Rear:

16x7.5 = +65mm (e.g. stock) [minimum of +60mm]
17x8.5 = +59mm (e.g. Mugen MF10)
18x8.5 = +55mm [minium of +50mm]
18x9 = +60mm (e.g. WORK MEISTER S2R)
18x9.5 = +65mm

The way I see it, and what I am requesting clarification on is:

1. If a rim is 1" wider than stock with the exact same offset, the outer face of the rim will sit exactly .5" further from the vehicle.
2. Considering the Prodrives (since that is what I am looking at) the front rim is 7.5" wide - that puts the outer face of the rim .5" further from the vehicle. The offset on that rim is 48mm, stock is 55mm. That puts us another 7mm from the vehicle or approximately .28". Therefore, we can expect that the rim's outer face will sit about .78" further from the vehicle than stock.
3. The Prodrive rear rim is 8.5" wide - that puts the outer face of the rim .5" further from the vehicle. The offset on that rim is 54mm, stock is 65mm. That puts us another 11mm from the vehicle or approximately .43". Therefore, we can expect that the rim's outer face will sit about .93" further from the vehicle than stock.

I guess what I don't understand is why for a wider rim, the offset isn't greater to help keep the tire/rim tucked. If there is clearance inside, I would think that would be desirable. At least maintaining the stock offset would make it so that you only came out .5" (in the case of the Prodrives). Can somebody (Jim) shed some light on this for me??

Yellow Streak,

I am the author of the wheel offsets you found in the FAQ.

I stand by the specifications except for the last two rear wheel offsets.
They would be better off as:

18x9 = +65mm
18x9.5 = +70mm

To answer your question...yes, a higher offset is desired. The problem is that there are not alot of wheel companies that cater to our extreem offset. Sure you can get custom made wheels with perfect offsets, but get ready to spend some serious $$$.

7.5 width, +48mm (front)
8.5 width, +54mm (rear)

Yes, the dimensions you mentioned will make the face of the rim stick out more than stock.
But, some persons like the face of the wheel to be flush with the fender. There are limitations, when you start rubbing though.

I am running similar offsets on my lowered s2000.
18x7.5 +48mm, 225/40/18 T1-S
18x8.5 +50mm, 255/35/18 T1-S

The face of the rim is flush with the fenders. Lucky for me that the T1-S does not have monster tread width, because I would be rubbing. The offsets on my wheels are not perfect, but they do not rub even though my car is lowerd (tight 2 finger gap)...and they look good.

 

The wheel/tire is pretty flush with the fender.
Again, the offset is not perfect...but these are for the street/show.
You get the best dry weather performance out of your stock wheels and tires anyhow (with the exception of using 205/55/16 and 245/45/16 R compounds).

 

Unicron,

in case you want to add them, the Volk CE28n sizes are:

front: 17x7.5 50mm
rear: 17x9.0 63mm

Thanks,

Ted

 

Phantom-

Thanks for the info - I appreciate it.

I am going to lower my car with the stock wheels/tires first and see if that gives me the look I want. If not, I will have to decide on something different.

Excuse me for butting in. I am looking for the S2000's stock rear wheel offset. Did you guys say that it's 65mm??? I was looking into putting them on my Prelude. I am not sure if they are going to fit now??? I thought that my Prelude's offset is 45mm, but I heard it from some that it's 55mm??! Either way, 65mm is too much of an offset I guess!!!

Well, since the rear wheels of the S2000 won't fit the front of my Prelude, I might just put the same setup of the S2000, front wheels up front and rear wheels in the back!!! That should work right!!?

 

MugenDriver,

Do you have both an S2000 and Prelude?

I think it would be better to use 4 front s2000 wheels on your prelude.
