4x140 - 5x100 Wheel Adapters


Recommended Posts

Hey guys, So I was reading of the guy here who was making the wheel adapters but the company relocated and he lost access to the mill and lathe.

 

Well, being that it is getting harder and harder to find all the parts and cars that we need to make our cars 5 lug, I have been thinking.

 

I have a friend you is a genius and by the way has his own mill. So I asked about the wheel adapters and he was making the years ago for jeeps when he was into that.

 

He said it was really easy. And said he would make me some, with me wanting to learn how to run the mill myself, he would teach me.

 

I was wondering, if things go well and I can make more, would any of you guys be interested in getting some for our Subies?

 

Chime in and let me know. I know I will be probably making two full sets to start off, so let me know.

if they are built proper then you can almost guarantee you can sell them. problem with adapters is the original studs break because it shifts weight on the outside of the centerline of the hub. since people redrill, why not drill out hubs to heavier studs then make an adapter?

You know there's someone on here making 5x100 rear hubs (which is the hardest part of converting except for moving the handbrake to the rear)

ok, it's more work, but you get better brakes out of it

I'm going to do some research, but,,,how hard would it be to make a new hub that is 5 lug that just bolts on? Take off the old 4 lug hub itself and then make a 5 lug that just bolts on in place?

 

You guys that have had some of the adapters, please comment on durability or problems you may have encountered plus some have mentioned that we need the extra spacing of the rim? Is that true? if so maybe we can make the hub with the extra spacing.

The hub is far more complex than an adaptor. The adaptor just needs some round bar turned down and 9 holes drilled (4 counter sunk). The hub has the spline to deal with.

 

For an MY, yes the stock (Subaru) 5 stud wheel offset is higher than a 4 stud so you need to run spacers or find other wheels to keep the same track. Typically this isn't a huge issue if you go to wider wheels as the offset of the wheels is addressed by the wider wheel size. I don't believe this applies to L-series (Loyale).

wheel adapters will work, just be prepared to do wheel bearings as it will push the rim to a more negative offset because of spacer thickness. i was just asking if there is a way to put a bigger stud in the 4x140 bolt pattern to help hold the adapter on. then use nice beefy 5-lug studs. i used adapters on a 280z, we had only wheel bearing issues. never broke an adapter or stud, even at 500hp

it wont be too negative. i mean if you have say a +45 offset on the rim, and a wheel adapter 20mm thick, the offset off the wheel now looks and acts like a +25. it just moves the centerline out more, which can be good for added tire clearance for lifted cars. no way to correct it really and no need to. it will just widen the track width and give a little more clearance
