ARK contacted me to let me know they had an opening a day early for install. As promised here are pics of the car on the new set of springs. As mentioned earlier, these are gold and are confirmed to be slotting in with their GT-S line. Their GT-S line is a lot more aggressive than their orange GT-F line, which I suspect I had on before these although it was never confirmed.
The springs I had on before measured 27.5" from the ground, through the
wheel centercap, to the apex of the wheelwell arch. These new springs measure 26.75" using the same reference points. Unfortunately, I did not measure what the stock height was so I do not know how much lower the car actually is.
According to the guys at ARK, the first springs only lowered the car 0.75" while these lowered it 1.3"-1.5". Again, I could not verify this because I did not take before measurements when it was stock. Maybe somebody who is stock can measure using my same reference points and let us know how much of a drop it really is.
Overall, I am extremely happy this time around with the drop, as the wheels are visually flush with the fender. There was no rubbing whatsoever from any corners, even at full lock. The ride is surprisingly even more comfortable than it was with the other springs. These are not stiff in the least bit and I am definitely not riding on the bump-stops.
