Can I get wheels machined for 5/8 studs? Anyone done this?

My 8.8 has Moser axles in it with 5/8 studs that look like they screw in then have nuts on the back of the flange to keep em in place. Do they make 1/2" variants of these? or Can I get my wheels machined to fit over these studs? Ive been looking online and I cant even find 5/8 tapered lugs even if I could get em machined though...

its always something
 
depends on what type of wheel it is i think. i dont think they make a tapered 5/8 lug nut. so you would have to drill out the rims and also put a flat counter bore big enough to accept a 5/8 lug nut. other option would be to pull your axles out send them to moser and have them drilled for 1/2 studs with the same bolt pattern. strange also does it think its about $120 or so. takes about a week or 2.
 
If you look at roundy round stuff i think you can get 5/8 tapered. Call or look up Allstar Performance. What wheel do you have? Most "racing" use a shank lug that's 5/8 O/D/ which doesn't sound like what you have. Plus if you have a tapered seat 1/2 now, and you drill it to 5/8 you won't (most liely) have anough clearance left to re-apply the taper to the new hole...again dependoing on what wheels. Having the axles redrilled or even selling those and buying new ones might be a better option. I'd love 5/8 stids for my 4 lug fox!
 
Well, right now ive just got a set of the summit brand prostars, but it looks like those will be up for sale.

The reason I asked is because I wanted to be able to run a set of street tires as well, probably an 18" Saleen wheel package. Ill prob just get a set of Weld RT-S which come with 5/8 holes.
 
I've never looked at a summit star are they solid rims? If they are solid I don't see why you couldn't just drill and ream the holes to a .6875 to slip fit over the studs and then use a regular washer and 5/8 nut like you would on a weld pro star. The Street tire deal you would have to find one with a big enough opening to fit the 5/8 nut and washer in but I don't see why the same wouldn't work. As long as the holes aren't sloppy I don't think it would be a problem.

Depending on the power level of your car I'd probably just pull the axles and send em out to get 1/2-20 holes put in em. Probably spend less money then selling/trying to modify the wheels.

I might be able to modify them at work on one of the cnc machines I don't think it would be that hard honestly. I'd probably spend more time picking up the holes and making sure the bolt pattern was on center then putting the actual holes in.
