So far on my is350 I have the f sport sway bar kit and the springs/shocks. Car feels great now. What handling mod do you guys recommend next?

RR Racing front LCA bushing. Then the IS-F steering ecu upgrade.

What does the IS-F steering ECU do to the handling?

+1 on the rear brace. I just installed it last night. Took it out for a spin. Car feels well planted. I'm on stock suspension on a AWD IS250. I now have the RR LCA Bushings, Rear F sport bar 19MM, upgraded to poly sway bushings F/R. I don't regret one part so far.

Yeah f sport rear brace and rr racing bushings.

Since this thread I have done the rr bushings which are awesome for braking and cornering the front doesn't wander at all, just a tad bit harsher but nothing crazy. With bushings, bars and suspension the car feels amazing in the corners so much grip with my pilot sports. Takes the corners better than my sisters frs. I'm going with the brace next, so if any one has one let me know.
