gta wheels dimpled & non dimpled

[moyersgn]

Bought a set of gta wheels off of craigslist. They are four fronts. They are two dimpled and two non dimpled. What's tbe difference if any? All four wheels are stamped front on the inside. The deal was too good to pass. All input is appreciated. Thanks.
