I think you'll find from those that own a Special Edition XFire, the wheels are much easier to clean than the standard SRT-6 version. Having the gunmetal grey clear-coat in the 'hard to clean' areas of the wheel makes the overall wheel cleaning effort easier. The downside is that you'll have to be careful what type of cleaner you use since there are clear-coat painted surfaces to deal with.

Personally, the Special Edition wheel is better looking.
