Shelby Cobra Chrome

Anyone know how to make the chrome look better? I rendered this in v.2.32 with yafray using raymirror for the chrome, but for some reason I can’t get those rough looking edges off of the chrome shading. Help

I posted it before, but here comes my chrome settings.

Material color = totaly black
Standard shaders
Reflective = 1.0
Specular = 2.0
Hard = 50
Radiosty = off (I dont know why I did it, I think you can set it on also)

RayMirror = on
RayMirror factor = 0.48
Fresnel = 1.6
Fresnel blending factor = 1.38
