Wilwood dynalite front drag race brake question

Vented is all thats important to eliminated warping on hard braking. Drilled helps kick the dust when applied said braking. I didnt opt for the drilled for mine but its a replacement part you can get later if you want or vise versa. Part numbers are included in the parts list/instructions for both. The rotor screws into the hub so you can replace without hub replacement on a wilwood brake assembly.
