once u have the underbrace on you will feel more of the road response to wheel. at first I felt so weird when driving, because my car is pulling on some road and steering shakes so bad but when I'm on good road car won't shake and pulling. in the beginning I thought it was alignment issue so I had it check out at STILLEN and once they did the test drive with me then we found out, because the underbrace so it tighten the vehicle so there is less flexibility on chassis then you will now feel more responsive road condition. I'm the first one have it on, they use my car for the R&D so I'm sure u will feel it more once u drive on more different condition roads.
