This weekend i borrowed a set of mustang 4 lug welds, the secondary lug pattern fits perfect all u gotta do is buy Shank type lugs. I also fit a set of stock mustans 4 lugs on but they required the lug holes to be drill out about 2mm bigger then stock placement. Just a little bit of info for anyone looking for cheap drag wheels...

is it safe to enlarge the holes?

if it is, im buying a set of mustang cobra style 5 spokers :D

no, not really. Mustangs are 4.25, supras are 4.5. Lots of aftermarket wheels made for mustangs come with both

Enlarging the holes can be done. I've seen it done.

Some wheels have steel inserts. These can be removed, the holes enlarged centered on the desired bolt circle and larger inserts installed.

Wheels that don't have inserts can be redrilled with slightly larger holes to the desired bolt circle. Then shouldered lugs like the stock MK2 wheels have be used.

There is a limit to what can be done.

yeah, it can be done but its hard to keep the wheel centered with ovalized holes, theres always imbalance issues. People use uni lugs to mount wheels with ovalized holes. They're supposed to be a pita to use

so any idea what a set of these wheels cost? I obviously would not go for the skinny ones up front but it would be nice to have at least a 15x8 all the way around in the draglites....they looked pretty cool on russ's car when he had them on there.

Drilling the holes larger then installing "inserts" is what is normally done in the industry. You can usually do it some 4.25 to 4.5 fitments.

Exactly, the holes are not "ovalized", but a large diameter round hole is drilled in both cases I stated.

Be careful, I would have someone who is a professional do it. You dont want to be traveling at 70+ miles per hour and then develop major balance issues. If a professional does it you can blame him and probably get a new set of rims if something F's up.

if your wheel falls off at 70mph, the professional better bring a big fuckin bouquet to your funeral.

and yeah, i thought the going to a pro thing was kinda obvious, not too many people have a drill press that can handle pieces as large as a wheel, never mind the accuracy thats needed.

My 15x8 centerline wheels I believe were from a mustang. The holes were a little oval shaped it seemed from enlarging the holes to fit our pattern.

They were used for almost 10 years and I personally took it up to over 135MPH and it was always stable.

the holes in the 15x8 5 stars i have have been ovaled by a machine shop and the car i got them off of had them mounted for over 2 years with no problems. its all in how its done.

If they're hub centric, then it should be ok to re-drill the bolt holes.
If not, and you're expecting the bolts in oval holes to centre the wheel, then you can expect some vibrations.
