Disc Brakes Australia Front HD Series 4000 XS Drilled & Slotted Rotors for 90-06 Jeep Wrangler YJ, TJ & Unlimited

Slotting increases the bite of the pads. This helps pull the car up more quickly. Used on its own, the process doesn't involve removing as much metal as cross-drilling, so it doesn't result in as great a weight saving. However, slotting can be as effective as cross-drilling in combating the problem of 'outgassing', particularly with the nine uni-directional slots fitted to each side of DBA Slotted rotors. The slots pump away gas and restore full contact.

The 'micro-shaving' effect of the slots also serves to de-glaze the pads (this is why the edges of the slots on DBA Street Series rotors are not chamfered or 'radiused'). It also tends to even out the wear across the brake pad faces, increasing the effective contact area. This can extend rotor life.
