Powerstop Cross Drilled Rotors?

[FLiP Sp33d]

Are cross-drilled rotors just for show or do they really dissipate heat effectively to the point where it dramatically improves braking? I figured just the front rotors will do since most of the load is in the front.

i'm pretty sure cross-drilled rotors would improve braking more than solid rotors. since the solid rotors can't spread heat away from the rotor as easily, it heats up more. the cross drilled has holes. when the friction between the pad and the rotors goes over the holes, it can push some excess heat into the holes and then it can be released later. the extra air through the holes also helps cool down the rotor itself.

yah they are very ood

i only have slotted as drilled can sometimes crack under extreme fatigue

for the price get both front and rear or the braking will will unbalaced and you will get over steer

also will be a little more brake dust

Sk,

Sloted? is that holes also? (a pic might better explain) :P

ProZac,

cross-drilled rotors have many little holes all the way through from one side to the other.

slotted have grooves on the surface of the rotors, sometimes in a curve from inside opening to outside edge.

both are for rapid heat dissapation to prevent brake fade.

sorry skp, I was in the neighborhood.

no problem stevie

as long as it is a good answer

which it was :chairshot:

here's a pic of a drilled rotor...

and here's a pic of a slotted rotor...

hope this helps prozac...

Here's a pic of rotors with both holes and slots. Are these rotors overkill?

over kill i doubt it just a good improvement

i would have liked to get a nice combination one

but remember no matter what anyone says the camry v6 rear rotors fit

but are not the same diameter

also the ones pictured are ok not a real high end one

more of a die maker grinding out material

compared to a nice curve in the slots

also a chamfered edge or a bevel will help reduce noise when braking on a slotted

the same goes for the drilled to have a lip around each hole
