Powerslot Front Rotors GT and GS

[Russ]

Excessive heat can cause resins in your brake pad to vaporize or "outgas." As the brake pad wears, the used friction material turns into a fine dust. This boundary layer of heat, gas and dust builds up between the pad and rotor surfaces and inhibits performance. Here's where Power Slot's slotted brake rotors make a big difference.

Power Slot's exclusive Vac-U-Slots are machined into the rotor and help evacuate gasses and dust, shed heat, and keep the brake pad surface clean. And in wet, raining conditions, our Vac-U-Slot helps push water off the braking surface for better stopping power.

The Vac-U-Slot also serves as a visual wear indicator. The slot is machined to the rotor's minimum thickness where it crosses the outside edge. If you cannot see the slot along the outside edge, the rotor has worn down to its discard depth.

When you need something tougher than a Power Slot rotor, but you're not quite ready for a big brake kit, try our new Power Slot Cryo rotors. Powerslot has teamed up with Frozen Rotors to offer cryogenic treatment on our Power Slot rotor line.


Deep cryogenic treatment is a one-time process that permanently improves the performance and service life of metals from brake rotors and engine parts, to machine tools and gear sets. Using a proprietary computer-controlled process, the metal is cooled gradually to -300F and then slowly returned to room temperature and heat-cycled as the final step. Although not apparent to the naked eye, the improvements to the rotor are significant. The cryogenic treatment process redistributes residual stress in the rotor giving it an extra level of protection against warping.


**Any Power Slot slotted brake rotor can be cryogenically treated prior to shipment.

Part numbers:

• Front slotted (GT/GS) : 589 PSL & 589 PSR
• Rear slotted (GS) : 592 PSL & 592 PSR
• Rear slotted (GT) : currently not available (as of 08 Dec '07)... 3G rear brakes will NOT work as the 4G rear brakes are vented and the 3G's are NOT.

Available through the following vendors:

Hmmm... looks like Tearstone doesn't carry them anymore. No brake pads or rotors to be found anywhere on their site.

They *are* for sale here, but I haven't bought from them before.
