Stickier tires increase the maximum possible loading on the chassis bushings. The sloppy feeling also comes from the rear dampers being too soft for the stock rear springs. Bilstein B6 help a lot there. The front struts are ok from the factory so fitting Bilstein B6 to the front isn't really essential. I did this in two steps just to see what the effect of rear Bilsteins only would be. If budget is tight just do the rears first. The BRZ handles well with this set up.
A 20 mm front bar helps tighten up the front end as you turn in although since Whiteline also supplied me with poly bushes and beefy drop links to go with that bar it may be that most of the effect comes from those better components.
Finally, MCA traction brackets are amazing. The reduction in anti squat jacking forces which otherwise move the rear suspension around as you corner is impressive. Also, wheel hop is eliminated by fitting these brackets. They give the geometry this car should have from the factory. Bonus, they drop the trailing arm connection point level with the rear subframe bushings so ground clearance is not affected. Good in winter. About a 2 inch drop in the front mounting point for the trailing arms is a lot to achieve and it works extremely well.
