I keep hearing a lot about these subframe connectors would these really make a noticeable difference on my stock gt if I was to put a pair of these on my car.
Its not that they make the car "perform" better, they allow for less chassis flex. As you mod a car, they should be on your list since they improve aspects of both drag and road racing. Its a mod you do before you start running ETs or slicks and if you plan on auto crossing.
