Well folks stock ISF handling isn't cutting it for me.
I am having trouble finding any solid threads with detailed specifics on any parts that are proven to increase the handling of the IS-F.
I am interested in a good shocks/springs combo that will slightly lower the car and be valved for a quick rebound without bounciness or squad/dive issues.
Usually a good set of shocks and matching linear springs take care of the body roll issue but if there is any tie bars proven to work I would appreciate if you let me know what those are.

You found F sport sway bar to work well in IS-F application even though is was made for the x50 models? I checked with Lexus and they said it wasnt meant for ISF and the one we have is the best to none.
Coilovers are great and all when set up correctly off course. I am looking more for a cup kit or good springs and shocks combo where the height is always constant so I don't run into extra such as corner weigh etc. I looked into Swift springs and so far like them. I wish someone gave more detailed review of the changes.

I am using all the throttle the car could offer. The car has an annoying squat that is related to the shocks mainly. Also body rolls like crazy starting at mid entry (when you shouldn't use any throttle). When you pass the apex then it settles down when you give it throttle, that's of-course if you made it pass the apex fighting excessive body roll. Not to mention the car is lazy at tun-in's to begin with.

Some, have tried corner balancing coilovers, F-sport rear sway bar, all of which I am planning on going with myself. Another member (SCCAForums) ran 285's on each corner to reduce the under-steer. I'm currently on 245 F, 275 R, and along with coilovers, and the sway bar I plan on picking up a set of fronts with 275's for track days.
