Hi Kevin,
If you are referring to to the 2point UR brace at the front most part of the car then yes. There is a definite night and day difference. If you already have an RSB, this UR front bar acts just like an RSB for the front. The car is just even that much MORE responsive and planted at the corners. The car feels like it's on rails. Get one you won't regret it. Now as far as ground clearance, there is no way you can drive your car slammed. You loose about 2-3 inches.
