^ I was asking about the Ohlins springs that come with the c/o kit.
It states 60 N/mm front and 70N/mm rear (whatever that translates to in lbs).
If it's really 336 lbs F and 400 lbs R, that seems out of whack. That rear rate is softer than zsp rear springs
For the swift springs, Harold has been recommending 336F, 672R for primarily street driven cars.
