I cant find nice wheels for my small car :'(

One option is to find a friend with a milling machine and redrill to a more common pattern. With a 4 bolt pattern it's pretty easy since you can put the new holes between the old ones. I did this with my wifes old spitfire because of how expensive the wheels were, redrilled the hubs and rotors to a 4 lug VW pattern and had a good selection of wheels.

Ok . . . and perhaps I was a bit hasty in judging.



I believe OldJeep has the answer you seek.

Many of the 4 lug aluminum wheels have a solid back and drilling for a new pattern would be no big deal.

In fact, a whole new bolt pattern would not be necessary.
You could mill the original circular holes to oval going toward the outside or inside as required and end up with a Uni-Lug style wheel that doesn't need specially shaped/machined washers.
Round washers would do it.

A set of thick - 1/8" or so - washers (Centerline makes a nice one)
would clamp the wheel down properly.

This style Uni-Lug is fairly common with aluminum wheels made from the mid-80's onward.
They work well and a lot of guys use the thin mag lugnut style washers with them, but they tend to "cone" inward and let the torque values drop off.
The thicker washers cure that.

I've run a set of these Uni-Lug style older mags for 42,000 miles on my 32 roadster with no problems.
510# + engine torque available and used now and then.
Which goes to show the Uni-Lug is an ok design for high horsepower applications although I would not use them on the drive wheels at the drag strip.

The 10" wide pair of 15" rear wheels I run were approved by SEMA when I bought them new in 1985.

I was actually talking about redrilling the hubs and rotors on the car, not the wheels.
