The SS track deflectors look to more-so simply deflect air towards the caliper and rotor hat.
The CT5-V BW deflectors look to attempt to scoop/guide air more strategically to the center of the rotor hat.
What are the part numbers on the CT5-V BW deflectors?

They look it but don't have the lower front "finger" that might help some cars and hurt others via ground clearance. I'm keeping the SS track ones on my 17 SS 1LE and put these 5-V BW's on my new 22 ZL1 1LE that I just got since it is lower up front. I have all the ZL1 1LE aero on the 17, but, it's stock ride height FE4 suspension yet rubs the lower front finger on the SS track deflector as mentioned earlier.
Should be PN's 85536980 / 81.
FYI - on the rear deflectors on the 4 / 5-V BW's, they have external park brake calipers vs. drum-in-hat, so, they can get away with ducting towards the wheel bearing area besides the rotor without worry of debris getting into the drum-in-hat assembly. I'm not putting any of the rears on, and I have never had any rear dust seal heat damage in all the different "flavors" of brakes I have used on my 17 (J6M, J6H, J57).
