I'm looking to change my brakes soon and have noticed that both the ATE Power Discs (slotted atomic groove) and Zimmerman X-Drilled rotors are very reasonably priced (less than $50 a rotor). I know that the Zimmermans should be the better brake, but was looking for comments. How do they compare? braking? warping? cracking? uneven wear? excessive wear? cheese grater (eat pads)? Any experiences?

And what pads would you recommend? ATE? Mintex? Pagid? Metal masters?

They seem to break much better than stock compared with stock... They still feel really true (no warps or wobbles). The one thing is that they kick a LOT of dust all over my pretty white Ronals! I guess they might be cheese graters... I'd imagine that the Xdrilled ones kick less dust. Now, I don't run them like hell mind you, I bought them mainly becaused they looked way badass for not too much more money...

Re: I have the drilled Zimm's front &amp; rear and they work fine. No problems at all.

Just get some EBC Green to Mintex Red Box pads to eliminate dust

and i (used to) do a lot of 90-55s and they stopped my car like a champ. theoretically the xdrilled should be better and i might try them next if i have lots of $ and nowhere else to spend it.

Crossed drilleds should out perform slotteds, I was more worried about reliablity. But if they hold up thats good.

Now brake pads? ATE? Pagid? PBR? Green stuff? I hear good things about them all. Can anyone point me in a good direction?

And what about the drums? I'm not very up to date on whats out there for drums because I've never really cared for them. Any good shoes?

EBC Greens or Mintex Red Box....

Also, I noticed EBC has slotted and dimpled rotors that look very nice too. But they are kinda pricey($150 a pair) and still probably aren't as nice as x-drilled.

one last quesion: what about steel braided brake lines?

Cross-drilled rotors are generally considered to be a racing application. The holes are for cooling the excessive heats generated in a racing environment.

Cross-drilled rotors are actually LESS efficient on a road car than are solid rotors.

Brake rotors on road cars rely on swept area for grip, and drilling holes may look cool, but it also reduces swept area for contact with the pads.

Think of it as being like slicks on a race car for maximum adhesion. Grooved / rain tires channel water away from the contact patch but they do that at the expense of contact with the road. The greater the contact area, the greater the efficiency, with tyres on the road or pads on the rotors.

A comparison could be made to the carbon fibre wings mounted on the rears of so many economy coupes of Japanese origin.

This so-called aero device has no effect until the vehicle reaches speeds upwards of 120mph, something the car rarely, if ever, attains. The wing actually adds extra weight and causes increased aerodynamic drag, essentially resulting in a NEGATIVE effect to the car's normal running.

In other words, carbon fibre rear wings and cross-drilled rotors in street applications are a gimmick.

Nope, no crossed-drilled for me . . .
