I knew you had a WRX, the springs are the same, the only difference is that the spring rates are more suited to the WRX, and mine are more suited to the GC8, otherwise the springs are the same. Same deal with the suspension setup and camber adjustment. Under the skin, the cars are *fairly* similar. In fact, the springs I have on my car were owned by a guy who had a GC8 2.5rs, then he bought a WRX wagon and had these springs on that car for a month or so. He said the spring rates were a little soft and they lowered the WRX more than the GC8, so he sold them to me and got some Whiteline springs. You might want to look into that as another option as well. If I remember correctly, the Tien GC8 springs were also rated at like a 1.8" lowering, so I am speculating when I say that they'll also be a little lower than that on your car.
