===EBC===

These are budget brake discs and are ideal if you are looking for good fast road performance but you don't want to spend thousands of pounds on upgrading your braking system.



'''EBC Sport (Drilled & Slotted)'''

[[Image:EBC_Gold_Discs.jpg|thumb|150px|]]

Wide aperture grooves
Special disc alloys UNIQUE to EBC
Dimple hole construction
Balanced geometry


The wide slot draws cool air across the pad surface keeping pads and discs cooler. They also expel dust, dirt and hot gases better than fine slots which eventually fill with rust and scale.<br>
The blind drilled holes are there to break down surface gases when braking hard from speed but do not weaken the cross section of the disc as can happen with discs that are drilled all the way through, thereby lessening the chance of the discs cracking due to heavy use.<br>
These discs are standard size OEM replacements with a cosmetic surface coating that helps prevent unsightly rust, however the coating will soon go and the un-braked surfaces of the disc will rust.<br>
The grooved and drilled design means the pads and disks run cooler but the surface area reduction means braking efficiency will be reduced unless the brake pads are upgraded to a higher friction compound to compensate. So if you add extra friction to better cooling you will have better brakes. <br>
Extra benefits of drilled and grooved discs is the effect the slots have on maintaining a flat smooth pad surface during the pads wear life. The slots encourage the pads to wear with a more flat pattern and the "Ribbing" common with non slotted rotors does not appear. This removes the "Record groove" effect of pads on plain discs, particularly around the outer edge and helps pads maintain better contact area with the disk through their life.<br>

'''EBC Ultimax Black Anodised discs'''


EBC Ultimax discs offer much quieter braking and feature a special paint process to prevent corrosion. Note that the black surface will go away on the part where the brake pads touch the disc and this area can/will rust. How fast is depending on how the discs are used (and brake pads). I have read reports from 2 month to still being totally black after 2 years.
