With SP Performance Slotted Brake Rotors, you will feel the difference. Its series of slots wipe the surface of the rotor forcing the gases to expel through the slots. The slotted surface also greatly improves wet weather braking by preventing hydroplaning between the pad and rotor. The slots on SP Performance Brake Rotors are machined to the minimum thickness. This is done to insure that the rotor strength is not compromised, keeping safety and reliability in mind for virtually all automotive cars and trucks. This is a bolt-on, hassle free way to greatly improve your stopping performance. These rotors are electro-plated with a bright Silver Zinc Finish to give a more appealing look. Electro-plating forms a metallurgical bond between the plating and steel, forming an iron rich alloy with tenacious bond where it will form its own protective oxide layer. Electro- plating is very effective in combating the corrosion of the rotor .
Note: Please check Title and Product Features to verify the vehicle application to make sure these rotors will fit your vehicle before ordering..../ 85-88 Oldsmobile Firenza - Front Slotted Brake Rotors / 55 oldsmobile
