Slotted rotors for volkswagon are made using the highest quality Original Equipment replacement blanks. Competitors will sacrifice quality by using inexpensive off-shore castings. Typically these brake slotted rotors are made of inferior porous material and often have less cooling fins than the OE brake rotors. These fins also serve to reinforce the brake rotor and guard against warpage. Slotted rotors always meet and/or exceed all OE specifications. It is also important to know that the exclusive Vac-U-Slot is tapered to enhance evacuation of heat and gases.  Slotted brake rotors are manufactured to the highest tolerances keeping SAFETY and quality the number one priority. Slotting, unlike drilling, doesn't compromise the structural integrity of the brake rotor. When you drill a brake rotor you weaken it and cause stress points that can lead to cracking and ultimately failure. Also, drilled slotted rotors lose considerable surface area compared to slotted rotors which means less active braking area for pad to brake rotor contact. Brembo Slotted  brake rotors help evacuate gasses and dust, shed heat, and keep the brake pad surface clean. And in wet, raining conditions, the slots help push water off the braking surface for better stopping power. The slot also serves as a visual wear indicator. The slot is machined to the brake rotor's minimum thickness where it crosses the outside edge. If you cannot see the slot along the outside edge, the brake rotor has worn down to its discard depth.When combined with performance brake pads such as Brembo brake pads,  slotted brake rotors will deliver superior braking performance under the most severe driving condition. Most  Slotted brake rotors feature cadmium-plating to protect against corrosion. In testing, cadmium-plating lasts up to 60% longer than zinc-plating and many times more superior than no plating at all.
