Cross Drilled Rotor for Gen2

These are some info on types of brakes..

The OEM Gen2 Rotor can be modified to cross-drilled rotors.. if im not mistaken, its around RM35/piece..

Blank
Blank brake discs have no dimpling, slotting, or drilling. They are just a clean, smooth face. The advantages to blank brake discs are that they have the most surface area, are very easy on pads, are the cheapest, and resist cracking very well. The disadvantage is that they don't have areas to expel gases. However, that disadvantage is pretty much a moot point considering most modern pads don't build up gases enough to create a skating effect. However, most of the time blank rotors are not available with directional vanes, which is sometimes a very big buying point.


Drilled
Drilled brake discs are essentially blank brake discs which have had holes drilled or cast into them. The cast holes will resist cracking more than simply drilling holes, but if the drilled holes are chamfered correctly no problems should be had. Also, buying a drilled rotor which has been cryo-treated is a good idea. The idea behind drilled rotors was to create areas for the gas which built up between pads to be expelled. Another bonus is a lighter overall disc, thus lighter rotating mass and less unsprung weight. The least important bonus is that they look blingin'. However, the disadvantages are: decreased cracking resistance, increased pad wear, decreased brake disc surface area, and higher replacement cost.


Slotted
Slotted brake discs are blank brake discs into which grooves have been cut. The grooves may extend in an arc to the outer edge of the rotor, or in straight lines. Advantages: less prone to cracking than drilled, usually cheaper than drilled, often have more surface area than drilled, lighter disc, blingin'. Disadvantages: increased pad wear, decreased surface area compared to blank. Often available with directional vanes.


Slotted and Dimpled
I can't see a point other than some people may consider them more blingin'. Buy 'em if you want, but don't pretend the dimples actually do anything.




Drilled and Slotted
Combines both drilling and slotting in one disc. Too much loss of surface area makes these bling-only. Almost every professional race team in the ALMS runs either drilled or slotted brakes. (Mostly SLOTTED[stupid me]) I'm fairly sure the combination was created for looks, not track-worthiness.


In the end, slotted wins. Slotted rotors will simply be the best for any street-based car. Coupled with good composite pads, they will offer the best fade resistance for lasting pedal feel and worry-free stopping.
