Under and over steer are controlled with the sway bars. The Eibach adjustables or the Strano adjustables are an awesome way to dial in the car. Changing the setting completely changes the personality of the car.
The balance was off with the Steeda rear springs, i had zero rake and front end was pushing. Balance was better with the stock springs, but a bit too much rake. The 55D spring kit fits nicely in my setup.
I will be shopping for sway bars next spring. There is a nice set of adjustable Eibachs on sale at AM, but i have already busted my Mustang budget for this year. Car is also going in the garage for the winter first week of november, so no more mods at this time. I will be looking at Steeda swaybars
