Fill and drill wheels

[Shaun @ Tru6]

I can get these older Can-Am wheels, 10x16s for a good price. They are 2 piece wheels with bolts hidden behind fingers. Bolt pattern is 5x5" which is off just enough from 5x130 that they won't work. The backspace is also too small.

I would like to:
Fill the 5x5 and redrill with 5x130

Fill the barrel holes and either bolt in or weld in the center section with a larger backspace

Can this be done safely? Any recommendations on who can do it?

There is a wheel shop near me that routinely welds/re-drills lug patterns, but they are typically for the ghetto sleds. Not sure I would trust this procedure on something that goes fast and corners hard...what about adapters?

[Geronimo '74]

I'd suggest adapters too.

offset inserts?

[techweenie]

I wouldn't do it. Redrilling/filling is the easy part. Lots of machine shops can do it. Few will because of the liability. The wheels are not hub centric and will give you balancing headaches.

Offset is too low for spacer/adapters. If you can disassemble and raise the offset to accommodate adapters, you can get them custom made to be hub centric in & out. But by then you're into the setup for a buttload of money.

One other option is rotate and drill. Leave the 5 holes as they are, rotate and drill 5 new holes in between the existing ones. Small color coded caps can be used to cover the old holes.

That's a good idea, there's certainly a lot of meat in there, the center section is quite thick. Weighed a wheel today, comes in at 17 pounds.

also thought of modifying the hubs to take a 5x5" stud pattern. I imagine a machine shop could do it easily and might be stronger/safer than modifying the wheel center. Then I only have to move section in the barrel.

[Shaun @ Tru6]

Bill, I don't think custom hubcentric adapters will be more than $100 per side, so with moving the center in the barrel, still way under 9x16 Fuchs in price, and really want the 10x16 for the 265/45s. Another good idea, thanks. spaces will add 2-4 pounds though at each side, the only downside.

Looks to me ,like those wheels use a sleeve/cylinder style lugnut, rather than the ball seat or cone nut---only about 3mm or so between the diameters,which is only half that at the bolt hole radius.I would drill and sleeve the wheel to fit the chosen lugnuts. That style holds the wheel on with a big flange or washer on the nut,and the drive
is via the cylinders or lugnuts rather than the usual tapers. --Safe.--- Nice looking wheel.
Do it.

[Shaun @ Tru6]

That's a good possibility Bob.

I'm thinking more and more to modify the hubs. Take them to a machine shop with the wheel, or just the center and have them modify the hubs for both spacing and adding a hubcentric ring.

Then I would only have to get the center moved which should be easy for any good wheel shop.

I know this doesn't help much, but do whatever it takes. Those wheels are awesome. I love the stuff that's a bit more obscure. Good luck. Show pics when mounted please!

Shaun, it's your car so do as you want.
The wheels are removable - they change - do you ever think you may need to fit a spare some day or move to rain tires? Or go back to stock to sell the car?

Mod the wheels and other stock wheels still work - mod the hubs and only one set of wheels will work (or add multiple sets of 5x5 for all your wheel needs , sounds like a $$ answer)

I have seen where the mounting holes are drilled oversized and an offset (filler/locating) plug is used.

I like the idea of rotating and drilling the best.

Technically, if you fill and drill there may be issues where the welded "fill" section has different strength compared to the cast wheel center. Stress risers over time could be an issue. For a street wheel you would likely not have any issues. Tracking them would be a different story.

Now, You could weld the holes up, then rotate and drill new ones. Have the best of both worlds. Might as well weld a hub-centric ring and machine them to fit while you are in there.

Call Tru design out in Colorado that does the weld up 17" fuchs with the 7s (vs 6s at Lindsey). I bet he can do some crazy stuff, is familiar with porsche wheels and knows 3 piece wheels so he could adjust the off set with a spacer.

[Shaun @ Tru6]

THanks All, and agreed, filling, rotating and drilling was my original intent. I like the idea of welding on a hubcentric adaptor.

Going to a local shop on Wednesday. Thatcher also gave me these guys: Wheel Adapters, Wheel Spacers, Hub Rings, and much more! | Motorsport Tech

One way or the other, I'll have these on the car at 5x130 and safe for DE. I do need to get them done as I'm doing a custom 10 inch flare fitted over the wheels.
