Disc Brakes Australia Street Series X Gold Drilled & Slotted Rotors for 99-04 Jeep® Grand Cherokee WJ
DBA's mid-series enhanced performance rotor features Thermal Stability Profiling for improved heat handling and Thermo-Graphic paint markings for effective heat monitoring. 4000 series rotors also incorporate the innovative Kangaroo Paw ventilation design, which runs cooler, stronger and outperforms traditional straight vane disc rotors by up to 20%. The unique 'XS' pattern is a premium (advanced) cross-drilled and slotted pattern, providing improved braking performance for street use only.
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.
