Always nice to get it right the first time!In the same boat here. Swift says the springs were designed for the stock Si dampers but with 50%+ stiffer rates who knows how long they will last. Might be better to just get it right the first time.
I had Tein Street Advance Z coils in my 3rd gen Acura TL 6mt and it rode like a dream. Had the dampers set to Tein's recommendations. Height was about 1" lower than stock.
Note that the Flex Z coils for the 10th gen Si has spring rates much higher than stock. 336 lbs/in (6kg/mm) all around.
