A set of stock fogs are going to be expensive through Subaru. You'd be better off going to www.rallylights.com and getting a set of Hella FF1000s and the WRX mounting brackets. They'll be about half the price and twice the light. We've got a discount there too, make sure to let them know that you're an MNSubaru member.
Doh! I didn't know we got a discount. FYI, the FF1000s are driving lights and the Hella 500s are fogs. I am putting both on my car but putting the 500s in the stock location because they fit better. The FF1000s are pretty big.
I have 500s on mine and they are wicked bright. Plus, they have clear plastic covers available to prevent future chips and cracks. They are literally at least twice as bright as the stockers.
