Do brand name rotors really matter?
Hi I'm sorry if this is a repost I've tried searching for this but didn't find anything. I have a 2004 350z with standard brakes. I wanted to change my rotors to a drilled and slotted that I found in the group buys list. I found a non branded rotor and was wondering if brand name really matters like stop tech, power stop, etc... Vs a no name brand. I hope some one can help me thank you.

do they matter? yes.
Does it matter if you buy total junk? yes.
Can you buy reasonable rotors for far cheaper than name bran, which is really what youre asking?Yes
Ebay, brakemotive is the seller name, i pay 189 bucks for all four drilled and slotted rotors and ceramic pads.. and i change them ALL every 2 years.

Brake rotors is a very simple concept, but the key to long lasting rotors isn't just about metallurgy, but also runout AND installation.
I've ran and sold many different types of rotors. Some cheap rotors have very very good metallurgy, but what makes them suck is the amount of runout they produce due to poor machining or a lack of it. Runout causes the car to shake and shudder as you apply the brakes.
Some rotors have average or poor metallurgy, but they do outlast some rotors because of the lack of excess runout.
Poor installation also causes excess runout due to the unevenness of the hub and the rotor hat. To minimize runout, the two unevenness must be installed in a way to offset each other. Runout can be minimized when the rotors are indexed using a dial gauge set that costs no more than $30 a set at Harbour Freight.
So yes, brand name matters. Premium brands of rotors such as EBC, Centric, Raybestos, have great metallurgy as they consist of alloy metals. They are also machined in a way to minimize runout if mounted on a straight hub. If you are lucky, sometimes the cheap rotors may have good runout as well either by fluke or by design.

$140 for both rear and front.. Lol I just ordered some, I didn't know people ran the ebay rotors on here. For that price I can afford to replace them every year or two.

+1....i'm interested in hearing you out. On a side note, NOT part of the question, I've heard that drilled rotors can crack under heavy load.
This was pulled off a google search, but i've seen rotors with sections completely broken off.

Then again I will NEVER be a complete "brand name *****."
