New Rotor reccomendations?

[Jon11582]

Cryo/frozen rotors are cryo'ed to re-form metal particles that the rotors are made of and re-align them.
Think of when drag racers smoke their tires, what they are doin' is straightenin' the tire molecules to get better grip of the tires.

I don't get this. Why would one be better when frozen, and the other be better when warmed up, when the goal of both is to produce friction?

And I'm not sure what you mean by "straightening the molecule" either. Molecules move around, and molecules that move around more have more friction. How does freezing something to way below freezing allow you to re-form metal particles? To reform something, you need to separate it first, and you need to melt something to do that, which you do that by raising the temperature.

The reason drag racers do burnouts is that they burn off the outermost layer of tire, giving them a clean surface to launch with, and to raise the temperature, which increases friction of that new layer.

I know it sounds confusin' wit cryo-ed rotors, but that's what it does.
Article below explains it.
All you have to do is search cryo rotors or somethin' to that extent and you can read up on explainatations about it.
They also cryo crank shafts also, you can almost cryo anythin' to have them last longer.

im getting a good amount of vibrations while braking, espcially at highway speeds, so i know ive gotta replace my rotors and pads. but i was wondering do people usually do all 4 or just the fronts?

[Dawgz]

^ im going to replace all four, why replace just the front two?

[hari-bhari]

because they handle 80 percent of braking, and the rear ones might not even be worn out. what kind of pads are u gonna get?

[Dawgz]

i just got new pads all around, i forgot what brand they were tho...but they were of good quality.
