PSA: the Konig wheels I bought had a few defects. 3 out of 5 wheels had an issue. I exchanged one of them, but the replacement also had weird defects (2 wheels had a fingerprint on them, that was made when the wheels were still drying off, and was right near the bead), a 3rd wheel wheel had dust particles embedded in them. I'm sure it wouldve been fine when mounted, but I was not happy about it.
Long story short, I returned them. Yes, they are way cheap, but I guess in the end you get what you pay for...
Also, I was not happy about them being black. I HATE black wheels!
At first, I convinced myself that the performance gains would outweigh my hate for black wheels, but in the end, I could not accept it.
Most importantly, I did not like the idea of lowering the offset. I did some back-to-back tests (between the stockers and 42 offset TD 1.2 wheels) and determined that even the small amount of offset change (-5), affected the torque steer to the point that I hated....
So, in the end, I decided that I will deal with the crazy heavy stock wheels, in order to preserve the handling characteristics that Ford designed into the car.
