i wana dump my car but scared of the ride.. im on 20s and is going wit edfc but not shure which damper any suggestions??? air is out of my range..

 

Flex is stiffer, your car will handle great and these will allow you to go lower than CS. CS is a comfort shock, so the ride will be smoother, but you cant slam it as much and might bottom the fronts if you drop all the way down .

Do a search on CS to find the thread of pics of slammed cars on CS.

 

CS on 20s is decent, imho
all in all, depends on the overall look you're aimin for

 

Well, you really can't have it both ways.

RMMGS4 is right on. If you want to "dump", then the Flex would get you lower. The Flex is not overly harsh and will depend on what kind of a ride you can deal with. I've had both and prefer the CS since I did not want to totally dump the car and wanted it to still feel like a Lexus, well as best that it could anyway.

Once you lower and go for lower profile tires, the Lexus smoothness is gone. On the plus side, the handling improves and the bounciness is greatly reduced.
