KVR Performance Brakes

[wedge]

Does anybody have any experience with KVR Brakes?
I'm looking into getting a set of their cross-drilled rotors and semi-metalic pads.
I'm looking for anyone who knows how well they work? Noise? Brake dust? Performance? Are they worth the cost? Or possibly any other brands that might be better for me. Anything you can tell me.

I have a set of the pads and slotted rotors.

Pads: somewhat noisy, especially for gentle stops. First stop of the morning is a horror story (I drag my brakes the 50 yards to the main street to get a little heat in them. Surprisingly they are fine after first warm up, even when on extended highway cruises.

I have never had drilled rotors from them. Our lead sleds need all the mass we can get for repeated hard stopping, so slotting appeared to be the wiser choice for an upgrade for me.

Quality is high, though many rave about the Porterfield pads being every bit as good without the noise.

I have some of their pads.

They stop better than OEM but are squeeky at times...

Thanks for the help guys!

Cross-drilled for what purpose? Cross drilled rotors are useless now days since pad compound has advanced and the gassing process no longer occurs.
In the past, brake rotors on competition cars, were drilled in order to let the gas generated by the friction between the pad and the rotor escape and avoid brake fade. Know days there is no need for drilling them, not even for cooling the rotors since the cooling will ONLY take place around the holes, since the holes are not drilled perferctly a part of the circunsference of the hole will be blunt wich with the temparature during braking (hard or regular) and some pressure will cause the hole to start cracking and when you lease spect it.... bye bye rotor, hello tree.

If you look closely on any competition car, be it NASCAR, WRC, F1, IRL you will notice that no one uses cross drilled rotors but slotted ones. The reason behind the existence of cross drilled rotors is simply because there are people who still buy them out of misinformation or just for looks. If you build it, they will come sound familiar ?

Any way, there was quite an extensive thread on this at the altima.net site witch I would recommend everyone to read.... It's a looooooooooong thread but worth every minute.

Get the pads.

Good for daily driver + track.

i had called them, in ottawa, they were extremely helpful, great service, i didn't get the pads though, but for sure that's where i'm getting my next set

x-drilling does still serve a purpose...perhaps discussions you have read missed them...weight. Big brakes make great levers against your motion, but if you already have enough thermal capacity to stop on the track all day long, shedding the weight becomes more important, and easy. Look to the ALMS GT and GTP classes. Most run drilled, but for the unsprung weight loss where they have enough mass in the rotor. Trial and error though, as hard braking tracks will see more solids and higher speed tracks will see more drilled depending on the car.

Street cars however, are almost always under braked for performance driving, and do need as much mass as possible. Drilling these is not always a good plan, but for normal/average street use, they are normally fine, and the appearance thing is more important than function at that time. Cracking is only a secondary and minor issue compared to thermal breakdown.

F1 IRL etc (cept asscar...never bothered to look what they have) don't use traditional metal rotors...they use some sintered iron varients, or exotic polymers and real reinforced carbon.

That thread is already posted in the sticky of this tech forum

x-drilled rotors also release the pressure build up and cool the pads to reduce brake skid.

I have Vented Brembo's and Hawk Pads upfront. They work very nice for street and rallyx events. Personally, I think it would be better to have vented or slotted or a combo over x-drilled.
If you are worried about getting too much heat in the brakes, just throw a naca duct up front and run some ducting to cool'em off.
The one thing I would like to have on the trdcel is rotors all the way around with a hydraulic handbrake.

Well, I can say one thing about KVR. Their service is amazing! I ordered a set of pads/rotors on monday, and they arrived the very next day!
They're being installed on thursday, so I won't get to see how well they work out until then.

And there they are finally installed:
