Spring Rate advice for ITA Miata

[tnord]

1.8L with Eibach Spec Miata 27mm front 15mm rear sway bars, I'll be using Kumho V710s 205/50/15

i have the SM bars as well, but will be using Koni 8041 Race shocks instead. the SM bilsteins can't effectively dampen the higher spring rates, as they are just OEM street shocks from the R-package cars.

i just bought 850 and 800 to try out for the front, and 400 for the rear. we'll see how it goes.

if i were you i would go down to like a 700lb front spring (from 750 iirc) and use the SM rear (350?).
