Installed GP sports knuckles, having some issues?! - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I installed a pair of GP sports super knuckles that I purchased second hand from a user here on Zilvia, and I am having some issues after installing them. I noticed before installing them that the top hole where the knuckles bolts to the coilover is offset just a bit for more negative camber, like this:

Now, I didn't think to check that they were the exact same on both sides, but they were both offset in the same direction for negative camber, and they both looked the same to me. And I would assume from a quality company such as GP Sports that they would be the same.

Anyways, the issue I am having is this: On the passenger side of the car, I have about 1cm of clearance between the tire and coilover. On the driver side however, the tire is hitting the coilover.

Things I have tried:
Switching wheels
Cleaning behind the rotor
Notching the coilover for more positive camber
I could go on notching further and further until the issue goes away, but I don't think that is the "correct" way of doing this.

The rotors I have on the car are OEM Brembo Z32 rotors I purchased new a few months ago and never had any issues with them.

I am baffled here. The only thing I can think of is that maybe the knuckles were bent, but I have never heard of this happening and they looked to be fine.

TL;DR Installed new knuckles, now my tire is hitting the coilover on one side. Halp.
