F-1 Fenders will flow with the NSX Ducts, but I don't know about the hood.
Contacted Henshin Auto about the F-1 fenders - their response was that only the X-1's are made for the celica so I guess that's my only choice if I decide to get them...
Don't worry, X-1's look really good. But with the Hood
and NSX ducts, you might not even need custom fenders.
