I have 1 Carbon Fiber and 1 Alumalite Splitter for a 370Z Amuse bumper. Both were bought brand new from Fly1, never mounted, and have no holes drilled. Asking $200 for the Alumalite Splitter and $350 for Carbon Fiber; these are $300 and $400 new respectively, plus $80 shipping each. Local sales only (Central Jersey). More photos available on the Fly1 page linked below.
