Default F-sport spring rate?

Trying to debate between installing f-sport springs and buy shocks or going with coils. I'm curious does anyone know whats the spring rate for F-sport springs? I know majority will advice to go with coils but I want comfort and a minimal drop. Any help would be appreciated.

Later today, I will find the Lexus F-sport brochure with spring rates (progressive).

I]ve been runnig the Eibach 350 springs for over 1 year (same as F-Sport springs), if your goal is comfort and minimal drop then you will be satisfied.

F-sports are progressive, so the rate changes-
Front- Initial 47 N/mm, Final 66 N/mm
Rear- Initial 40 N/mm, Final 70 N/mm

In contrast-
Stock non-sport springs are linear and are 45 N/mm front and 51 N/mm rear

Drop is 25mm front, 19mm rear, compared to stock non-sport pkg
