Wilwood dynalite front drag race brake question

There is not a weight saging from the standard rotor to the drilled and slotted rotor. Its minimal at best. Id say 1 pound total for all 4 wheels but thats really stretching it.

There is a difference from the vented to the solid rotor drag style they call it. The vented wont heat up like the drag rotor. It also wont warp like the drag rotors do if they get to hot(think short shut down or panic braking). After that the only difference is slight dust dissipation during a breaking event of dust allowing an ounce of better break application.

So the solid rotors vs the vented rotors are a bit different. One is a 1/4 thick ish and the other vented rotor is about 1/2" thick which has vents between surface contact area to keep the rotor cooler during applied brake forces.
