If anyone knows about the RSi hakka's, they are "the" tire for awd cars. Their tire has the consistency of a tire at 75 degrees when the driving conditions are at 20 degrees. Thus you get unstoppable traction. I drove my car through 2 1/2 FEET of snow in my driveway last year when I got stuck with my snowplow and had to go to work. I drive comfortably at 65mph in 4-5 inches of snow on the highway. I bought a new Wrx that has 17's so I will definitely be buying a set for that car as well.
I had these on my 2000 2.5RS. They will fit wrx 02-05 as well as any other subaru with a 16" wheel.
I had them sold, but the guy totaled his car on the way over to pick them up. Bummz
