I like the JIC one too, but I'm not sure if it's that ridged cause of the carbon fiber. I may be wrong tho. Comptech is good, but for a strut bar I think it's overated. I personally like the skunk2 and mugen bars.

It will improve, but not to the point of where you can really feel it. If you lowered it, it would help a bit more. Most people can't feel the difference in just a strut bar unless you're road racing. If you get the front you you should also get the rear. Good luck
