I'm going to say leave it off. Not a great looking lip IMO. I would either go with a full aftermarket bumper (Aerosync may be a good choice), or a more subtle lip like Veilside V1 or Mine's. Those lips look good on their own with the stock side skirts and rear bumper. Or go with no lip at all, push your wheels out with a little bit of tire stretch and lower it for a super clean, flush look.

 

thanks for the inputs guys i take it all into consideration. and yeah the tow hook mount will be painted black soon. my bumper is either factory and super strong and flexible or duraflex, you can literally kick it hard and it will just pop back so im not worried about cracking at all.
i personally really like the huge duck bill front lips they look soo aggressive which is why i chose to buy it in the first place.
i dont like side skirts or rear diffusers at all, i am gonna get some front mud guards and see if it evens out the lip. and i think the lip will fit the car better when i lower it with flush wheels.
