The black SS inserts would look best IMHO. Mine are painted from the first owner and it looks better than body color and about the same as vinal so I say go for it
Get the vinal inserts! That way if you change your mind later on down the road you can just remove it. Easy fix. It would look good with the black and red theme you have started already.
You should consider the SS inserts.... more contrast with your darker color.
With some chrome wheels to balance out the look, those stock wheels gotta go.
You can barely see the inserts in this pic. The vinyl inserts look cheap imo.

Just put the black reflective vinyl letters on my redfire. I would go with the vinyl also just like stated before if you don't want it later you can just take them off.
