I felt a slight difference in mine, but like stated above, you need to do some good turns to see its benefit. It will keep you a little flatter in the turns. Coupled with a fatter front sway bar, you'll be turning like a dinner plate lol.

 

I still have to get a STB, but right now, the car is so loose it's scary. Stiffening up the front end more would just make it worse.

 

I got one and it really did help the steering out a lot. I just need to install the front sway bar for balance. I have the rear sway and pan hard bar replaced and soon the rear lower control arms.
