Re:Making your own cross-drilled rotors
 

I had cross drilled and slotted rotors on my GS-T. I thought they worked well, but I sold it so I dont know how they held up.

Re:Making your own cross-drilled rotors
 

yeah, i heard about the guy that bought it, he was killed in a crash due to brake failure :-\ ;)

Re:Making your own cross-drilled rotors
 

I dont really see slotted or drilled rotors giving more braking force. if anything less.. less surface area.

also the slots and holes will just end up eating the pads unless you get like kevlar or metal race pads. (which will be WAY WORSE for street driving as they wont get hot enough).

think about it, the slot is going to slice into the pad on every revolution.

if you ask me, get some bremo blanks w/ good pads and you'll be set. slotted/drilled rotors are ricey in my book.

Re:Making your own cross-drilled rotors
 

the slots and holes are there to disperse the heat that is absorbed by the rotors during breaking, cooler rotors = better breaking, very funtional ;) have you ever noticed the ends of brake pads have an angle on them? as long as you get the rotor turned after you do it to make sure there's no debris that is above the level of the rest of the rotor the pad's slide right over it.

Re:Making your own cross-drilled rotors
 

they disperse heat but the main function is to vent hot gases/vapors from the braking surface because the materials break down at thousands of degrees and the vents (slots or cross drilled holes, even dimples) keep the surface of the pad pressed more firmly against the rotor by venting the surfaces between it and the rotor... it does the job well. Yea some, especially slotted rotors, wear pads faster. Id give up the pad life for the brake performance tho...

Re:Making your own cross-drilled rotors
 

if you have that much gas between the pads/rotors you're using the wrong pad compound for your driving.

and kevin, the angled edges of the pads eventually wear down.. smart ass ;)

go look at super cars. all blanks.

Re:Making your own cross-drilled rotors
 

it's still level with the rotor, i don't see how you think it's gonna 'slice' into the pad. go look at auto-x cars, all slotted ;)

Re:Making your own cross-drilled rotors
 

yeah it reduces fade and the brakes bite harder when you get into them... just get some and drive around, you def feel the difference. Any gas between the rotor and the pad reduces its efficiency

Re:Making your own cross-drilled rotors
 

If you ever look at real race cars ie Cart/GT cars...They have 100% solid disks. They just use a thicker disk...

I set of Brembo replacement rotors isnt that much (solid too) so why bother?

Re:Making your own cross-drilled rotors
 

thats because they are braking from 200mph and cant sacrafice structural integrity... plus they are really light
