Slotted or Drilled ?
Slotted or Drilled ?
Hey,I'm ordering some KVR rotors...i have the option of slotted or drilledhttps://www.kvrperformance.com/can/canada.htmlunfortunately can't be both....which would you go with? also can get in Black/Gold/or Silver....according to their site...click on 'products' the slotted may not be a good choice as they don't disapate heat as well and they recommend only for 'competition'. Thanks!

Get Slotted man. Cross-drilled is strictly for autoX. I would highly recommend getting the slotted. They are better for daily driving.InderEdit: Color is totally your call man. Your car.

on the KVR web site it says that slotted will NOT disipate heat quicker and will actually help the brakes get warmer faster?!?!from site:" Cross Drilled Discs offer an enhanced initial bite (more responsive, especially in wet weather)and greater heat dissipation (reduction in heat induced fade - "brake fade")as compared to O.E.M.They may also last longer than O.E.M. rotors (depending on your braking style),with 40% Better Cooling, 20% better stopping, improved wet braking,reduces rotor warpage, less brake fade and longer life."as opposed to:" Slotted discs offer cleaning of the friction material (brake pads), but do little in terms of additional heat dissipation.Slotted brake discs do not cool better than cross drilled discs or even standard discs.The face grooves will slice the brake pad material allowing the pad to bite harder into the disc, therefore causing an increase in disc temperatures.This is recommended for competition vehicles to bring pads and disc temperatures up to optimal operating ranges.(Race cars warm-up engines, tires and brakes for the best possible performance)."now you are telling me different?i'm confused...

http://www.4wdworld.com.au/tipstricks/disc.htmfound this too...read the last few paragraphs.and even more informative:http://autonet.ca/SunDrive/Tor....htmlthat last article seals the deal...cross drilled it is.geez with new michelin hydroedge and now cross drilled rotors...it better start raining around here soon!Here's an interesting bit of information...I called a dealer to see what it would cost to get the rotors and pads replaced at the dealer. The parts guy then asked, do you have steel or aluminum wheels? So i asked how that would matter to which he replied that in their system, they have part numbers for rotors to be used with steel wheels vs. aluminum wheels!hmmmm? Have any of you heard of this before?

Cross drilled rotors will fail sooner from stress cracks. Slotted rotors have more mass and less points of failure.I think TRD-4reel has good advice - street cars should probably stick with solid/vented or sloted rotors. Slotted rotors give the gas and dust from your brake pads a place to vent to instead of building up between the pad and surface of the rotor.Slotted is like an educated medium between cross drilled and solid. Brembo's FAQ also states that there are restrictions on the type of pads you should use with a x-drilled. No restrictions are suggested with a slotted.

I have been looking for alloys to replace my steelies, but now wonder if alloys would work with my rotors.

The swap from steel to aluminum won't cause any problems - just use a tad of anti-seize on any surfaces that meet the rotor hat to prevent corrosion from sticking the two togeather.
