Nope. Sway bars transfer force from one side of the suspension to the other. Chassis braces prevent as much flex in the chassis when it's under load. Think of your front and rear strut/spring combination as the corners of a box without ends or two seperate squares, but without one side (see below).

A strut tower brace ties the top of the box together and makes the box less likely to deform when it is pushed on (cornering force). This means that the geometry of the suspension stays more uniform and also that the forces involved in cornering are not lessened by flexing the chassis but rather are handled by the tires, as they are supposed to.


The front and rear box can't really be tied together at the top without running a roll cage through the car, which sort of spoils the luxury of a Lexus. But you'd have a very strong Lexus if you did.

(I tried to draw a couple of things to illustrate, but it didn't work right when posted so you may feel free to be more confused by my explanation than you were before.)

Eh, I wouldn't use the term "harsh"...it will stiffen it up a bit, but not to the point where I would consider it "harsh"...
