Accessory Rear Skirt

hey guys

what is the difference between the Sportback rear vortex skirt and the sport rear skirt?

i see on the audi webpage that you can get either or and im wondering why?

i have a rear skirt at home and im worrying that it is for a sportback - will this not fit my sport?

might be an obvious answer but i cant see the difference between the lower part of a sportback and sport rear bumper!

need to know guys

eg: sport...

thanks mate - but do you know what the fitting difference is??

forget those links - i only posted them to let you know that there are 2 different kinds

to go over it again - i have a sport and i bought a sportback rear skirt by accident

i havent tried fitting it but why are there 2 different rear skirts for each model??

i need to know this by the end of the week

thanks guys
