Forget what the others are talking about in terms of "hard to keep chrome ACR wheels looking clean". PM me if you want some tips on keeping ACR (or any mesh wheel) wheels looking great all the time. In the pic above, my ACR has not been washed in over 3 weeks, and I drive it almost daily.
On a side note...........Even not using the easy method I use, by chroming them, your making the wheel EASIER to keep clean, not the other way around.
In addition, if your that worried about a few pounds. Jon, the previous owner weighed the ACR's before and after chroming. I think he said the difference was 1-2 pounds per wheel.
