a lip on the front will help tie in all of the kit. the sides and the rear always looks good in fact I ran with those and a stillen front lip for a while. the only thing that bothered me was the sport spoiler was not long enough to really make the rear look right. I did not like the amuse wing thought it was to big and just wanted to extend mine to match the lines so I got a slip on and think is works great. Pics can be found in my albums of before and after i replaced the front bumper and added on the spoiler ad on. good luck
