BRZ suspensions
 

I am transition from a 4 door sedan to this brz thingy! and the ride is too rough (hard) for me .. LoL ..what is the recommendation to make the car ride a little smoothier? ...

buy a "comfy" car for a DD

Not much really you could do without potentially changing the handling characteristics of the car (if that matters to you). Dropping the tire pressure may help, but may affect mpg and "dull" the feel of the wheel. Getting aftermarket "comfort" dampers/springs may help, but again, may change the handling characteristics (more sway/dive I would guess). Perhaps swapping dampers/springs with an FR-S, I hear their suspension is (minutely) softer than ours.

I would suggest upgrading your struts/shocks while keeping the stock springs. Get in touch with @Turn in Concepts and see about upgrading to Koni yellows. The best thing you can do for ride quality is to up the quality of your dampers while keeping the spring rate reasonable.

FRS front springs are softer then BRZ and would probably ride softer.

How about 16" wheels paired with tires that have more sidewall?
