15"x6.5"
Rota Subzero i believe. A friend of mine is selling the set to me, I like the idea of keeping 15" so i can use the new tires i got.

Couple of my favs:

And all the rest:

I think it should go good with my faded black paint job, and primered hood.

Mmmm....those look damn tastey. :D Did your friend have those on a Subaru? Do you know what the offset is?

No, he bought them for his 5 lug conversion but never used them.

I'll try to get an offset.

One of the pictures you showed me had an offset shown on them I think. It was in teh 40's I think.

Mmmm...ya, it's that last picture and it looks like it says 40 even. I'm not sure if they're going to work for you. You'll want an offset between
48-52 mm ideally.

This is off I-club and explains a lot about rims and tires:

Here is some general wheel info pulled from our site (www.tirerack.com) concerning wheels. This should help people truly understand the issues involved with upgrading wheels.

Offset - the most common question

Image


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.

Zero Offset
The hub mounting surface is even with the centerline of the wheel.

Positive (Subaru Offsets)
The hub mounting surface is toward the front or wheel side of the wheel. Positive offset wheels are generally found newer cars, including your Subaru. The recommended offset of replacement wheels on the WRX (and most modern Subarus) is between 48 and 52 mm for best results without vehicle modification or added stress on axles.

Negative
The hub mounting surface is toward the back or brake side of the wheels centerline. "Deep dish" wheels are typically a negative offset.

If the offset of the wheel is not correct for the car, the handling can be adversely affected. When the width of the wheel changes, the offset usually changes as well. If the offset stays the same while you add width, the additional width would be split evenly between the inside and outside. For most cars, this won't work correctly due to clearances. This is why larger wheels (with greater width) usually have lower offsets - this pushes the wheel more outward.

Performance Benefits of Alloy Wheels

While many people choose alloy wheels for their beauty, there are equally important performance benefits to be derived including...

Reduced Unsprung Weight Compared to Steel Wheels
This is one of the most critical factors affecting a vehicle's road holding ability. Unsprung weight is that portion of a vehicle that is not supported by the suspension (i.e. wheels, tires and brakes) and therefore most susceptible to road shock and cornering forces. By reducing unsprung weight, alloy wheels provide more precise steering input and improved "turning in" characteristics.

Improved Acceleration and Braking
By reducing the weight of the vehicle's rotational mass, alloy wheels provide more responsive acceleration and braking.

Added Rigidity
The added strength of a quality alloy wheel can significantly reduce wheel/tire deflection in cornering. This is particularly critical with an automobile equipped with high performance tires where lateral forces may approach 1.0g.

Increased Brake Cooling
The metals in alloy wheels are excellent conductors of heat - improving heat dissipation from the brakes - reducing risk of brake fade under demanding conditions. Additionally, alloy wheels can be designed to allow more cooling air to flow over the brakes.

Plus Sizing

Image



Plus sizing your wheels and tires is the best way to improve both the performance and appearance of your vehicle. By using a larger diameter wheel with a lower profile tire it's possible to properly maintain the overall diameter of the tire, keeping odometer and speedometer changes negligible. By using a tire with a shorter sidewall, you gain quickness in steering response and better lateral stability. The visual appeal is obvious, most wheels look better than the sidewall of the tire, so the more wheel and less sidewall there is, the better it looks.

nabisco breaks it down a bit further into wheel widths and what you should use for the width.

Please people, do not just quote random specs- offset is directly related to rim width- you can certainly use a +55 6.5" wide rim on most late model Subarus, but you cannot use a +55 8" wide rim! Offset Nirvana is within a few millimeters of:

Width .... Offset

6.5" ....... +53 to +55
7.0" ....... +50 to +53
7.5" ....... +47 to +50
8.0" ....... +43 to +47

Anything within sighting distance of these ranges is happiness for your wheel bearings. I reserve the right to be corrected on the ranges, but they are about 95% accurate ;).

Thats probably a user prefference. I preffer more sidewall vs rim, I dont really care for super low-profile tires.

Anyhoo... anyone know what the stock width and offset of the stock 15" alloys are? Im going to contact the seller and have him clarify the offset, that 40 could easily be a 48 or a 46 if the hand writing is sloppy.

I believe that's right, everyplace that sells 15x6.5 have the offset at 40 rota does list that size wheel as 38 though, also the stock wheels are 15x6 with an offset around 53-55 according to this thread http://bbs.legacycentral.org/viewtopic. ... els+offset

did i hear right faded black paint job thats what paint i am getting i think those rims would look CRAZY good i would get a bigger rim thow

well, black wheels definitely ARE a current fad. Every ricer's getting into the jdm style. :)

Take what Thawa posted and minus 2 from every number for a better fit on our cars.
