I got the Aerokit Cup on my 997S and its scraping all the darn time, the GT3 front bumper cannot possibly be any worse. I was also interested in fitting the GT3 front bumper, would it really affect the aerodynamics though? I mean the car does have the same dimensions as a 997S right?

Side question, I know the GT3 front bumper has a lower lip that can be easily replaced in case it breaks/bends due to frequent ground contact etc.. the aerokit cup seems to have a similiar front lip, is it also as easily replaceable?
