So I have had it on my car for little over a day and I have driven a lot with it on. My car handles a bit better then it did before on turns going 80+. Now I ain't leaning to one side or the other in turns. Fuel mileage is a iffy situation atm cause I haven't seen a huge difference yet. This thing is incredibly sturdy and lightweight yet provides an incredible amount of down force for even a FWD car. I originally bought it for looks but I never thought it would do everything else it has done for my car. The only downside I see in it is that my top speed has gone down on hills and turns a bit but that's understandable since I haven't changed the down force for it yet since I installed it so we will see what happens. As for install it was easy except the measuring. That was the hardest part to the job.
