I have the lower brace only and you do feel the difference. Its not massive but then it costs £30 so you won't transform the car! It is noticeable and worth the cash + 15 mins to fit. The only part that was wrong was for some washers that were totally not the right size so I just left them off with no adverse affects. You will definately notice the better turn in and the car does feel "tighter" as a result of fitting it. You wont be disappointed as long as you don't expect miracles.
