So the higher the offset, the less a wheel will stick out.
The lower the offset, the more a wheel will stick out.

This is correct.

Lol!! I thought I\'d grasped it!

Guess it\'s not quite that simple, just found this tho which explains a few things:

Offset is the distance from the wheel center to its mounting surface. To find offset, plug the rear wheel spacing and width into this formula:



Offset = Rear Spacing â€"_Total Wheel Width
                                                  2


If you have a "positive" offset, the mounting pad is in front (or outboard) of the rim centerline. This situation most commonly occurs on front-wheel-drive applications. To picture this more accurately, think of the convex design of many wheels found on front-drivers; the center of the wheel sticks out further than the edges of the wheel. If there\'s a "negative" offset, the mounting pad is behind (or inboard of) the rim centerline. This is typical for most standard rear-wheel-drive vehicles and "reversed" rims. Sometimes, this style is referred to as a "deep-dish" wheel.

For example, an 8-inch wide, 3-inch-rear spacing wheel would have a 1-inch negative offset. Conversely, if the same 8-inch wheel had a 5-inch rear spacing, it would then have a 1-inch positive offset. Finally, if the same wheel had a 4-inch rear spacing (which is exactly half its width) then the wheel would have what\'s known as a "zero offset."

In wheel-measurement designations, the diameter is listed first, followed by the width. A 16x7-inch wheel has a diameter of 16 inches and a width of 7 inches. Diameter is measured where the tire rests, not from lip to lip.

I know someone whose just got these and is making them fit (not on an FD) - thats the spirit though and it will be cool

That offset calculator is exactly what we need  Nice find Lee, it\'s good that it confirms my calculations too

12" wide with a -3 offset, madness!  You could have small dogs using them as treadmills!  What car is that going on?  And for what application? :cool

[J4P RX]

Im not sure what car, but I think an S14.  Its still madness though and its going to be a fair bit of work.

My drift team are all kind of having width/offset wars at the moment with everyone trying to outdo each other.  A few people running negative offsets now with wide rims.  I think Pazza has 15x9 negative something on his corolla with a 185 tyre stretched onto a 9 inch rim.  Pretty mad but looks very cool!

Glad the offset calculator helped as this thread going back and forth just started confusing me.

Yeah thanks Lee, I was getting pains in my brain trying to work this one out!

Hope you get ya rims soon Chris as they look loverly in the pics.

Work rims only seem to come in 12" widths!! On an S14, interesting.... are they running wider arches??

[J4P RX]

Not yet, but its going to have front and rear or its never going to work.  Itll be done in Japan before the car is sent over.

Ive noticed a distinct lack of decent wheels in the UK.

They are all narrow like 7 inches with Nasty +50 offsets.  Im sensing opportunity, but have no idea how to makes wheels :p

Hi Mate....dont know whether this is of interest to you..but i have a nice set of rims avail in the vendors parts for sale section.ultralites....really really nice rims and great quality...would be great to get some of you guys on to them as they r a really nice rim!And not many people have them on rx\'s yet!

Cheers Matthew

Dustbin lids and some sticky back plastic? I could even print some proper Volk stickers - no one know.... :rollin

[chrisBoid]

Final spec sorted and ordered, after Rays got back and their spec matched up with my calculated spec

FRONT Volk GT-C Face 1 18 x 9.0J +30 offset (61mm dish)
REAR Volk GT-C Face 2 18 x 9.0J +17 offset (61mm dish)

Plus 4 centre caps and 4 sets of locking wheel nuts.

.....and rest.....

Roll on January.

[Initial-D]

Well done mister - bet your glad thats sorted!

Good news for me too as Shin\'s got my wheel nuts and center caps aswell! Drinks all round lol!!:D

[Prospec M/S]

Hi Ben, Chris,

Sorry for make you waiting so long time.
Ben, I have got lock nuts and 2 centre caps somehow, and waiting for another 2 centre caps....
I will post what I have now at first in a few days.
Chris, 3 of wheels are ready to ship now, and waiting for last 1 wheel.
Please please do not ask me why Rays do such a way of business..... :rolleyes:

Anyway, slowly but definetly things are getting sorted out.

Regards,

Shin

Thanks for the update, I thought they\'d gone missing in the post for a minute!

[chrisBoid]

These look great in the metal. (more and bigger pics in the members ride section).  If they don\'t fit then I\'ll make them fit!
