There isnt as much for the gen7 as the gen 6 but still plenty of options:
PFYC makes a front lip a hood and a spoiler grille incerts and lower facia grille's
From GM you can get SE front lip side skirts a spoiler off of a GXP GPO front grille's
Do a retro fit of projectors into the headlights (stay away from spyder stuff on ebay)
HID's for reverse lights
