The Fsport shocks and springs I've installed on a non-sport suspension IS350 did feel softer than my IS350 with the OEM sport suspension. The Fsport website shows the OEM normal suspension springs rates at F46 & R51 (N/mm) and the Fsport at F47-66 progrsssive and R40-70 progressive (N/mm) . I'm going to try to find the data for the OEM sport suspension and post it.
I'm definitely interested in purchasing a swabar set for the ride.

You are very welcome 
N/mm = Newtons per mm
1 N/m (force)= 0.0057 lbs/in (force)
46 N /(10^-3)m = x / (1)m,
x= 46000 N/m = 262.2 lb/in
OEM
Front (262.2 lb/in) Rear (290.7 lb/in)
F sport
Front Progressive (267.9 lb/in - 376.2lb/in)
Rear Progressive (228 lb/in - 399.7 lb/in)

If you have not watched the suspension video...watch. Maybe its because I don't have the HKS exhaust or any aftermarket exhaust for that matter, but I love the sound!(I guess some people have said that it is a little too loud :s) Too bad they don't show some WOT action.
