Just checked Tire Rack. According to them the Verano has a 5x115 bolt pattern, the same as the Cruze diesel.

5x120 is a BMW bolt pattern.

I guess your question still stands... I haven't heard of anyone making the switch. Maybe it would be worthwhile on a higher mileage car that needs new wheel bearings anyways? They're not cheap, sold as a hub assembly that includes the ABS sensor and reluctor ring.

5x115 seems to offer a better selection of wheels to choose from.

The thinnest aluminum adapters I've seen are 3/4" thick, or 19mm. That means you would need to use a very narrow wheel and tire, like a 7" wheel and a 205/215, or find a wheel with a huge positive offset, like 60mm.

A custom made steel adapter could be made much thinner, but I haven't seen anyone doing that yet.

Cruze RS is either 7.5" or 8" (can't remember) with a 40-42mm offset. That 20x8 et40 Camaro wheel would fit perfectly if the bolt patter and hub diameter were correct.

I tend to agree. I haven't taken mine apart yet to have a look, but the difference is 15mm on the diameter, so the wheel studs will need to move outward by 7.5mm, more than 1/4". I would be surprised if there was enough hub past the studs to allow simply drilling new holes and pressing in new studs.

I think you should take one for the team, pull your car apart and post some decent pics and measurements!

Your best bet would likely be to stop by a GM dealer and ask to see both parts side by side. Having an accurate measuring tool, like a Vernier caliper, would be a good idea. Remember to check the size and spline pattern of the hub splines... I thought I read somewhere the Cruze diesel, Volt and Verano use a larger drive shaft spline, but I never did confirm this.

...i bet the surface area of the hub is larger and could probably accomodate redrilling to 5x120 but Ill look into that more.

It would only be a stud offset of 2.5mm.
