Default Difficult Question for wheel Experts: Getting "Custom" wheels made...

I've got a small question that i'm wondering if maybe someone here has a good idea about...

In case you havent been to the members gallery lately, i'm working on "restifying" (restore/modify) a 1970 Subaru FF-1 coupe. You can read more about it here:

http://forums.nasioc.com/forums/show....php?t=1351744

If you read through there, you can see I have a little issue with wheels...

A little background for those not knowledgeable about 1970's and 1980's Subarus. They have a VERY unique wheel bolt pattern - 4x140. Only two makes have ever used that bolt pattern, Subaru in those years, and some models of Pugeots. Here is a nearly complete list of EVERY wheel ever actually made in that bolt pattern: http://www.ultimatesubaru.org/80s/wheels2/wheels.html

As you can see, not much to choose from. Plus, anything other than the 13" Subaru wheels and the 14" and 15" Pugeot wheels pretty much are extremely rare and hard to even find... The only "new" production wheel that I can get are 15" Superlites via here: http://www.packracingproducts.com/
The problem with those, and the Pugeot 15" wheels that i'm currently running with 205/50/15 Hankook Ventus tires, is that they are far too wide for the rear fenders, and the Pugeots and 15" Superlites have an offset of +20! Waaay too low!

Here is a photo of the current 15" pugeots and tires and the fender issue...



Here is a picture showing the current gap between the wheel and the suspension...



Now i'd be willing to "tweak" the fenders a little to get tires to fit, but right now it would require whole-scale cutting and adding new fenders to do so. Plus, the tires just look too big on the car right now anyhow...

I have looked up 14" and 15" tires that are availible to see what I might want to run, and I have come up with a couple good options:

Right now, I have Hankook Ventus HRII's in 205/50/15. They were a cheap tire and what I could get at that time. They work great though. Their specs are:

Hankook Ventus HRII 205/50/15, Section width - 8.3", Tread width - 6.7", Diameter 23.1"

I found a good option for 15" wheels that is slightly smaller and may help with clearance, but might not be small enough...

Khumo Ecsta SPT 195/45/15, Section width - 7.7", Tread width N/A, Diameter - 21.9", Weight 17lbs, Cost - $90.00

I think those would work well with a 15x6 wheel with a +35-40 offset wheel, should clear the rear fenders better, and clear the suspension good enough too.

However, for 14" tires, there seem to be better options...

Yokohama ES100 185/60/14, Section width - 7.4", Tread width - 6.4", Diameter - 22.7", Weight 17lbs, Cost - $75.00 (These should clear everything fine with a ~+35-40 offset wheel)

Dunlop SP Sport 8000 195/55/14, Section width - 7.7", Tread width 6.9", Diameter 22.4", Weight 16lbs, Cost - $99.00 (Might still clear fine, also cost more and have less diameter but a higher cost)

And I also found this option... Kind of crazy being race tires (not 100% slicks, but R-compounds) and are on BLOWOUT through Tirerack for $59.00

Khumo Ecsta V700 185/55/14, Section width - 7.6", Tread width - N/A, Diameter 21.9", Weight 18lbs

I really dont plan on driving the car that much, and at $56.00 a tire thats just insane cheap for a sticky tire that would be fun to drive around! (I probably wont drive the car in the rain either, so no biggie there)

The wheel has less than 2.5cm (about 2.35cm) of clearance from the suspension. So a simular 6" wide wheel with say a +50 offset would HIT the suspension (being that offset is based on milimeters). An offset of around +35-40 seems to be about right IF I used a narrower tire.

As for the fender clearance, right now the rear tire sticks out about 2cm from the fender, but will need between 3-4cm less width in order to fit (3cm would be with a bit of fender rolling/tweaking but not cutting, 4cm would be clearing without any modification probably)

Now, according to my not-so great estimates, running a +35 offset 6" wide wheel with a 7.7" or less section width tire would clear the suspension fine and bring the tire aproximatly the 2cm inwards to the fenders...

In order to get clear of the fender (~3cm), the 6" wide wheel will need aproximitly a +40 offset wheel with a 7.4" section width or less... A 5.5" wheel with a +45 offset would also work with that simular section width of tire AND bring the tire in even closer under the fender.

Idealy, i'd use some other wheels/tires to check these results... But I think the best option would be to find out which wheels are availible and with what offsets.


So basically, my question is...

Does anyone know of somewhere I can have custom 4x140 bolt pattern, 14x6"(or 14x5.5")or 15x6"(or 15x5.5") wheels made with a +35-40 offset?

...mebbe ya could get someone to custom some hubs in a bit easier pattern....they will likely be needing replacement at some point, anyway???

....and god bless you for taking on this challenge......were I closer, I'd LOVE to help with it

....and on a thought.....some of our international members may have more of these older cars and thus access to wheels than those of us in the US

I've seen some 14" speedline/enkei-like wheels on Japanese cars, but those are even still very hard to find in Japan I presume... They were only actually made back in the day.

Custom hubs is not really an option either, and would cost as much as having custom wheels made I presume...

Only steel wheels though... But the price is right (aparently ~$80 each for custom wheels)

I've seen in my truck mags where they simply TIG the stud holes over machine flat and then drill new holes... I have no idea of what other clearence issues you might have with that though...

Those Stockton Wheels seem like the proper way to go though... good luck man..

if you're that close to rubbing with a +20mm offset you will be rubbing on the suspension with a +35mm for sure if you kept the same width tire.

that is as close to the suspension as I'd want to go.

if you need more fender clearance your only real option is a narrower wheel with a similar offset and a narrower tire.

All right, I think the big thing to do now is pick the tires so I can figure out what offset I need for the wheels... So the big question is: Go with 14" or 15"?

For 14" tires, I will definatly go with the Khumo V700's that are on closeout at Tire Rack (Khumo Ecsta V700 185/55/14, Section width - 7.6", Tread width - N/A, Diameter 21.9", Weight 18lbs). The smaller rotational diameter will make fitament easy, as will the narrower section width. I don't know the tread width though because Khumo doesn't list their tire tread width (although it is a less accurate form of measurement).

For 15" though, I've got it narrowed down to 2 choices...

1) The Khumo SPT 15" (Khumo Ecsta SPT 195/45/15, Section width - 7.7", Tread width N/A, Diameter - 21.9", Weight 17lbs, Cost - $90.00) It has the lowest weight i've found, plus isnt too expensive, AND has the same diameter as the 14" V700's which will make for a nice lower profile on a 15" wheel.

2) The Advan A043 15" (Yokohama Advan A043 185/55/15, Section width - 7.5", Tread width - 6.6", Diameter - 23", Weight 21lbs, Cost - $109.00) This is actually a specialty tire for the MR-S. Its good because its narrow for a 15" tire but not too narrow, probably has a better chance of clearing everything than the Khumo... However, its taller than the Khumo (almost the same diameter as my current tires) so there might be more clearance issues there. Its also the most expensive option.


I'm still not sure which one I want the most right now, but I think i'm leaning towards the V700 due to the price... Thoughts?

Tire Rack used to have some Kosei K1 Racing wheel blanks that were un-drilled that they could drill pretty much any bolt pattern in. Not sure what diameter/width/offset combinations they might still have, but it wouldn't hurt to contact Luke and see if they still have anything like that. They were pretty reasonably priced and pretty light as well.

Have you checked CCW? I know several autoxers get custom wheels made by them. They may be able to help you out. Link

Ouch, pretty expensive... But theres nothing in 14" or 15", 16" is the smallest they have.

f I had a larger budget, and was going to widen the fenders significantly, i'd probably go that route. Their "classic" style wheel is ideally what I was looking for.

How about this setup? This could be done for cheap via Stockton Wheels...

Heres those CCW wheels in what the 16" would probably look like. I'm not sure I can get a narrow enough 16" tire though...

u have rust around the wheel wells so u may want to consider flaring! if u going to up the performance, then definitely consider Kodiaks!

I wonder how well of a SCCA D/E mod car that could be turned into?
