Center bore - Can it be enlarged by a dremel?

omarmipi · 02-27-2005, 03:10 PM

I am looking into getting some oem miata or BMW wheels and I know that they have a smaller center bore then the sentra. I wanted to know if I can bore the center out with a dremel or other rotary tool. Would there be any problems if the bore wasn't perfectly circular? I had some miata rims on a sentra before but it cost $60 to get it bored out with a CNC lathe machine.

$60 for all four? That's cheap, I wouldn't screw with it myself to save $60. It wouldn't have to be perfect since it's toward the center of the wheel, and since the weight is placed on the studs. I don't know how much metal you're going to have to remove, you'd probably burn up a dremel trying to do that. Mine has a flexible spline sleeve that links the motor to the arbor, and I've burned it in half a few times using cutoff discs with it. An air powered die grinder would be tedious unless you've got an awefully big compressor to keep up with it.

i'd just take it to a machine shop and they can pop it on a lathe and enlarge the bore. If you don't do it perfectly round, you'll jack up the balance of the wheel.

I had thought about doing the same thing as well, but then I thought some more and realized it was not a good idea. Honestly, $60 is cheap, and you'd need a lot of sanding drums, rough stones, etc. - probably $15 worth of cutoff stuff, plus with the added aggravation, you know you'd probably just F something up

thats cheap! I took my rims to a rim show to ask them to enlarge 2 rims, he charged me 95 bucks per tire~!!! Those bastards

But what places do you go to get this process done?

lol, i tried doing this with corrado g60 wheels, then I realized i would have been there for a while. Trust me when i say that i live by my dremels.

I looked up some machine shops on the yahoo yellow pages and called around. Most people said that they had never done anything like but the one I went to hadn't done it either.

You need to call some wheel repair shops, not machine shops. Did you try your local Wheels America?
