I bought one of these radiators about 6 months ago.  I was pretty impressed with the quality of the aluminum, fitment, and welds for the cheap price that I paid.  If you need a new radiator for your WRX I would really recommend this radiator.

Postives:

- Working great for 6 months and counting

- Coolant tempurature ALWAYS lower then 1/2

- Good quality metal/welds

- Low price

Negatives:

- Don't tightent the drain valve too much, or else it will break the rubber ring on it, causing it to leak.

- Had to disconnect one radiator fan, because it rubbed against the radiator hose.
