Front progressive springs (2041) [1]. 60 mm at the coilover perch, 80-something (for the stock struts) at the top.
KW doesn't specify the effective rates, but they're definitely firmer than stock (still quite ok on the street though), but lower than the 90 Nm that I replaced them with.
Rear main linear spring. 110 Nm, 200 mm free length [2].
Some scoffs on the paint, if you care about those things.
$100 + shipping.
