Re: Suspension question/Spring Rates, etc.

The 200f/150r relates to 200lb/in, not kg/mm. IDK where you are getting the K from, is that to save hammering out a couple of 0's. Given the roughly 62/38 weight distribution and the double wishbone front and rear setup of 5th gens you want to keep the spring rates in line with this ratio to maintain a more neutral setup. The thread you linked has lots of common spring rates.

Pic link is broken. I have 450f/280r springs in the 4th gen with a 22mm solid rear sway bar and I can't quite lift a rear wheel going over driveways. You would need a much higher spring rate, really solid bars and some pretty heavily dampened shocks to achieve this which needless to say would be extremely uncomfortable on the street.
