@GregO These are standard springs for the industry, they have been around for years, but noone except Steeda figured out. @Mikepol2 came up with it here in the forum, if I remember correctly.
McMaster-Carr is the source for the US.
Btw. Steeda offers 95 lb/in spring for the S197.
Yup, back when I did the spring swap I don’t think anyone did the homework at sourcing various commercially available springs.
I’m fortunate to have McMaster just a few miles away from home.
