need good rotors.

[Brandon83]

I need to get my rotors replaced due to warping because i do alot of high speed braking and i need to get a good set of rotors that can hold up to my driving. What is a good set of rotors to get without killing my wallet. slotted, cross drilled etc. I was also told over the phone with tire rack that the brembo replacement rotors will do just fine because the slotted and cross drilled rotors dont provide as much of a gripping surface as the others. Is this true?

I got KVR Slotted and cadmium coated, and they do stop better, and havent warped, but they seem to have little spider cracks all over the surface.

Rotors arent something you want to cheap out on. Do it right, do it once, and you wont have to do them again.

They cryo treat all their rotors, use brembo discs, and they work great. They wont warp at all, and they will look good.

The only downside is that they arent "slotted or drilled", if thats your thing, which really doesnt matter.

They cost about the same as the KVR's that i bought.

I autocross and road race and have never suffered from warped rotors, either on the stock rotors that came with the car or the brembo blanks that I bought to replace them when I wore the originals out.

Just road raced yesterday, rotors had turned blue and purple from the heat. No warping.

What do I do?
1) Be anal about torquing your lug nuts. Get a torque wrench, make sure you know how to use it properly - read torque value while doing a steady tighten, if the nut isn't moving you aren't getting a proper reading, and make sure nut/bolt surfaces are clean and dry unless otherwise specified.

2) Let your brakes cool down properly after heating them up. If you're racing, use your cool down lap for just that - take it easy and let stuff calm down. When I get back to the pits, I cut the engine and drift into my spot at just a few mph, and with the engine in first use the clutch to stop the car, leaving the car in gear and the parking brake off. This makes sure the pads are a bit retracted and lets the rotors cool more evenly.

3) Follow proper rotor seasoning and pad bed-in procedures.

Yes it's true, because your rotor has a dual job: (1) - Be a heat sink for your brake pads and (2) - provide grip for the pads to slow you down (your tires actually provide the braking force for your vehicle though)

A solid surface has more mass and surface area than drilled or slotted rotors making it ideal in most situations for both job(1) and job(2).

So don't worry about getting the Brembo blanks...they are probably the best rotor for your application. If you are concerned about putting a lot of heat into the brake system, then you can always run some brake ducting and hose to help out.

Thanks for the help. Time to go order some rotors and pads.
