Drilled and Slotted or just slotted?

[Afboy143]

Which is best?? I already replaced the brake booster, possible the master cylinder is next. (Brakes are hard) I figure, why not do the rotors also. So, which is best, drilled and slotted or just slotted?

I would go with the slotted, a guy I work with is a racer (Vette) and also suggested the slotted. Drilled can break-off easier.

Drilling rotors works to pass more air through and around them, and allows for better heat dissipation. Slotting a rotor acts as a razor blade, kind of slices at the pad everytime it passes over it renewing the surface, keeping it fresh and working at its best capacity. Get crossdrilled/slotted combo for best results and best asthetics. Combine them with EBC greenstuff pads you'll notice a big difference

Hm with that said, how often will I need to replace my pads?

Are quality cross-drilled rotors really going to break in daily driving.. I dont think so, I would think that would be more of an issue in road racing.

I prefer slotted rotors. I have had no problems whatsoever with my Powerslots.

Good luck ....

I would say when they wear out. No, really though it depends on how you drive, the conditions you are in and so forth. It sounds much more harsch than it really is......and no, crossdrilled rotors aren't going to just crack and break, yet another unknown auto myth.

Personally I would go with the slotted rotors. NASCAR race cars use only slotted rotors because the drilled holes cause a reduction in the surface area that the pad makes contact with. Just the slotting removes enough heat so that they don't have big problems.

Drilled and slotted is overkill. Stick with the slotted rotors.

 

[stang99x]

If you want to over analyze the question of the slots, then you could seek deep enough to find that the pad will trap gasses in the slots that won't be trapped in the crossdrilled holes. Although the surface area arguement is a valid one, it is IMO negated by the reduced surface temperature and therefore less efficiant. Plus you get the cool look having the crossdrilled/slotted rotor!

how often do rotors just "break off"

yea pretty much never

I'm going with slotted cryo-rotors. I have no worries of the drilled rotors falling to pieces or cracking, but I have noticed a LOT of fly-by-nights advertizing Explorer Rotors drilled and slotted for $50 on eBay. THat scares me, so I'll go with a proven entity.

Second, i too have the powerslots and they have saved my ass more than a few times, BTW hawk pads all around

I was actually planning on getting those ebay rotors as they are so cheap

sometimes paying extra is not a bad thing

 

[02_ex_on_dubs]

the ones on ebay are the same size as stock but slotted/drilled, i bought them about 6 months ago and swapped them in with hawk pads and my stopping has never been better..

 

[UtahX]

There are also dimpled and slotted.

 

[gsx220]

i had the ebay rotors on my eclipse GSX they always stopped me at the track and i was normally pushing 130-140mph by the end of the 1/4 mile

i read somewhere that the drilled rotors can crack around the hole with enough excessive heat, dont know how much heat it would take to crack the hole, im guesing alot, but its just something i read

I would think this is in like crazy race application which my explorer is not


GSX220- Drill and slotted or just slotted?

UTAHX, whats the point of dimples? In my mind, the slots help the pad grip the rotor and the holes allow heat and gasses to get away from the rotor. What would dimples do?
