I am no expert here or nothing but I have been looking into this a lot and these are results I got from some people. 4 link will be able to be used on the street but corners are a problem with them, you can't take corners fast. 4 bars are better but can't take as much torque as a 4 link can. On my car I am going to go with a 4 link now, I was going to use a 4 bar instead but got talked into 4 link and my car will see some street and some strip both but basically it's like this... You can either have a full drag car or street car and if you wan't both then there are some things you have to sacrafice and handling and comfortability are some of those things.
That's my zero two cents on that!
