Wheel Adapters

A lot of people have asked about the wheels on the truck and how I got them to fit.  The wheels are off of a 2006 BMW M6.  My neighbor was throwing them out (no joke) and I figured I would see if I could make them fit on my truck. 

There were four issues:

1. Bolt pattern.  The stock bolt pattern is 5x4.75" or in metric:5x120.65.  The wheels are 5x120.  .65mm does not seem like a lot, but we would be putting undue stress on a very important part of the assembly if we tried to directly bolt them on.
2. The wheels are hub-centric.  What this means is that the wheel is centered on a flange on the hub rather than lug or bolt-centric, which means the wheel is centered on the lugs.
3. Offset.  The front wheels have a positive offset of 12mm, the rears 17mm.  This means that if I were to not use a spacer the tires would rub on the frame.
4. Hub size.  The diameter of the S10 hub is 70.3mm.  Way larger than the opening in the wheel.  This was going to be the show stopper.

Handling the first 3 was easy: I went to http://motorsport-tech.com and ordered some custom wheel adapters that converted 5x4.75 to 5x120, with a custom width of 19mm for the front and 28mm for the rears, and converted to hub-centric.  

For the hub size issue, the solution presented itself in the way of the S10 Blazer spindles.  The factory 10 pickup spindles look like this:

This means the rotor/hub assembly looks like this:

The wheel opening is smaller than the hub and prevents mounting (even with the spacer).  I was able to locate some S10 Blazer spindles on eBay and they look like this:

This allows the hub to bolt-on and allows the snout of the hub to be shorter. The spacer/adapter handles the rest (notice how much shorter the blazer hub is than the pickup rotor/hub assembly (above)).

Below is the spacer for the fronts:
