The Rally Armor urethane flaps are MUCH better than the OEM stubs, but for a Gen 3 they are marketed as Legacy mudflaps. Because the OB sits so much higher than a Legacy, they are too short IMHO. They could use an extra two inches..... OTH, Gen 4 owners can pick between Legacy flaps and Outback flaps.
On a lowered Legacy GT they look great, but in comparison,on your OB, they are going to be waaay off the ground.
I emailed them asking if they would sell taller flaps for our Gen 3 cars, and they never responded. Maybe if enough of us ask them, they will make a set that gives more coverage. But the Legacy flaps are still a huge improvement.
