I just got out of an '09 STi lease and I got 2 seasons from the summer performance radials, for day-to-day street use and the occasional lapping day or Autocross event.
At 24,000 km per year and 8,000 of that on winter tires, I'd estimate the life to be 16,000 km x 2 years, or 32,000 km.
WRX tires aren't as sticky but have better wear rating, so you'd get even better life with them than I did in the STi. Better than 32,000 km.
If tires seem to be wearing out prematurely, I'd check the wheel alignment. If you're pushing the car hard at events, I'd make that a performance alignment. Same price, more suitable for pushing the car hard. My STi had mild camber; -1.5 deg on the front and -1.2 deg on the rear and I was running Bridgestone Potenza RE760s.
