Solid or drilled and slotted rotors?

I wanted to know if there is really any reason to get slotted and or drilled rotors over the stock solid ones. I've read conflicting reports. Some say the drilled and slotted rotors will crack easy. I am just using the stock brakes on my 2000 gt and want to upgrade my stopping power by using the best rotor and pad combination I can. What rotors and pads do you suggest for stock brakes and daily driver wanting to stop better. Thanks in advance.

Slotted and slotted/drilled rotors sacrifice surface area for heat dissipation, drilled/slotted rotors tend to be overkill due to the fact that you can't machine them and they have the cracking problem. They dissipate heat so fast that they crack eventually, I had a buddy who's Shelby did that on a track day.

I personally run slotted rotors with some Hawk HPS pads with no issues. If you just want some better stopping power keep the blank rotors, unless you want the looks of the other rotors, and pair them with a decent brake pad and some stainless less steel braided lines.

My experience with different type of rotors, be it standard OEM, slotted, or slotted/drilled rotors are that all have their unique qualities. I personally do not use or desire to use slotted/drilled rotors, as too much rotor material or the rotor surface has been altered and eleveated due to design. And my experience with them is cracking that derived from the drilled portion of the rotor. I have enjoyed the stopping prowless of slotted rotors and would use them again. But a quality set of non-slotted or drilled rotors due have great stopping power too. A lot of times the basic caliper and piston design has alot to due how a rotor works along with the quality of the pad you choose. A good quality caliper with 2 or more pistons really is the icing on the cake per say to how a braking system functions . And I tend to go with a brake upgrade with oem style rotor with better calipers and great pads. Also a quality set of brake lines such as steel braided are in my eyes a great investment for years to come.

I know so many people that tend to go cheap when it comes to brakes, and in the end all it does is cause problems or failures in the end. Not to mention the safety aspect of the importance of brakes.

Ok well I'm going to stay with the centric blank rotors. I was looking at the hawk and EBC pads. Do you have any recommendations on those. On a side note I am also looking for a torque wrench from 0 to 20 in/lb for spark plug replacement, any suggestions.

Solid and I recommend Raybestos rotors. I use them on everything, never once had a runout problem and they are real high quality. Pair with Centric Posi-Quiet pads and you will stop REAL fast and no brake dust at all. Get it all from Rockauto. Stay the hell away from Duralast/Wearever/Cheap Napa rotors unless you like runout problems and pulsing brakes.
