Wheel backspacing.

Crazy thought - say you buy some wheels (say... 17x10") that have a 22mm backspacing. Won't fit, sticks too far out, blah blah blah.

What's stopping someone from bringing the wheels to a machine shop, and having the back of the mounting face cut in something like... 13mm, to give you a 35mm offset?

Just went and looked at the back of a wheel I've got in the garage.

Amazing idea, I must say!

Obviously they'd have to machine it perfectly flat so it doesn't create any problems...but I think that would be an awesome idea that I've yet to hear of! :)

never though of that but i think it would work! as sawbladz said the only think i could think would be a problem was if you machined off too much material and you might have a problem with integrety. Would it matter on what kind of material/ method the wheel is created (cast might be harder?)

Give it a shot with some sawblades first and see what happens and then I would try on some other wheels and let us know how it works!

Also, if you removed the material solely from the hub mounting surface you would have less clearance for the brake calipers.

I thought about that - obviously, before you go and yank a full centimeter off your wheel, you'd want to ensure everything has proper clearance, first.

As for the structural integrity, I don't think the thickness of the hub is going to have as much to do with it, as the design of the wheel itself.

It's an idea, that's all :) I'd like to see how much meat there is in the hub of a +24mm offset wheel (like a Mustang wheel ;))

you could take a look at two identical rims with different offsets and see if the manufacturer did just that or had a totally new cast made...

sounds like more trouble than its worth to me...but i dunno.

I had a feeling you were looking at Mustang wheels. lol They look great, are cheap and are a great width. Just a little too low in the offset. Figit brings up a good point. I would like to see some wheels in person to see how they change the offsets on the cast 1 piece wheels.

I think if the hub was overly thick and there was extra clearance for calipers, it could work. I wouldn't be the first to try it though.

I had considered that with my front TSW's I used to have. They were 20mm, and I wanted about 27-28mm, so I could run a wider tire. A professional wheelman near my home, told me you need at least 7mm of thickness from the lug nut seat, to the inside edge of the hub disk. $30.00 per wheel. Not bad, just never got around to doing it.

The wheels on the KAAZ D1 drift 240sx have had this done. I think they said they cut off 5mm or so. So, if they can do it you can do it.
