I have a widened set of stock wheels, and I had to use hub-centric adapters to make them fit. It has been about 6 months now and no problems at all. OP, the site you listed says spacers, but I know that some people call the ones listed 'adapters'.

Either way, the one that you are looking at is the safer method. The other option is simply a piece of metal that fits onto your studs, essentially pushing out the wheel. Your stud is made shorter by doing this though, and there lies the problems.

But like I said, I installed a similar set of spacers, mine were H & R 20mm. They are expensive, but from what some of the pros in the business have told me, as long as you install them correctly, and don't drag race a lot, they are very safe.
