Better off doing a search on here bud, folk have changed the bumpers, bonnet etc to the newer facelift s line.
I'd say the facelift 7 twin spoke s line wheels or the rotors would do a dramatic change for the better.
You get 4 replica 18" rotors for 399 new.
Depends on how much u want to spend
If its 8p1 its tein grill model am i right ?, if so go for s line front bumper and bonet probably find them in same colour on ebay and i know theres tons of rear s line bumpers on there, and a set of wheels and some nice shiny tail pipes if you dont want to spend too much
