Quick noob question. Is there a difference between the MK1 aero front bumper and the front bumper off of the GT3? If they are the same would I be correct to assume that lower portion (the extended black rubber portion) can be purchased seperately and adapted to fit?

Thanks for everyones help in advance

 

You are correct. The lower portion is called a lip.

 

as Deckman said you are correct, no adapting necessary.
We are of course going to need to see some pics of your car!
