Steeda's Powerslot rotors are a great upgrade for your Mustang and improve brake performance. Excessive heat under braking can cause resins in your brake pads to vaporize and "outgas" This gas combined with heat and brake dust form a boundary layer between the pad and the rotors which reduces brake performance. These slotted rotors provide a relief path under breaking for the gas and brake dust to escape. These slots also help with cooling. The end result is greatly reduced brake fade and elimination of pad glazing. Steeda's Powerslot rotors come with a silver cadnium plating for a bright finish that will not rust. Combine these with Steeda's Hawk HPS brake pads for excellent braking performance compared to factory pads and rotors! powerslot1 Powerslot Front Rotors 87-93 - 5 Lug Includes 2 Front Rotors for 1987-1993 Mustang 5-lug 469-8118-PSL-PSR$259.90 Powerslot Front Rotors 87-93 - 4 Lug Includes 2 Front Rots for you 1987-1993 4-Lug 469-8126-PSL-PSR$235.38 Powerslot Front Rotors 99-04 Includes 2 Front Rotors for 1999-2004 Mustang GT or V6 469-8141-PSL-PSR$229.50 Powerslot Rear Rotors 99-04 Includes 2 Rear Rotors for 1999-2004 Mustang GT or V6 469-8142-PSL-PSR$201.70 Powerslot Front Rotors 99-04 Cobra Includes 2 Front Rotors for 99-04 Cobras 469-8144-8145-PSL-PSR$296.40 Powerslot Rear Rotors 99-04 Cobra Includes 2 Front Rotors for 99-04 Cobra 469-8146-PSL-PSR$313.50 www.realspeedauto.com Ph.631-563-7325 All parts listed are for the Ford Mustang unless otherwise noted.
