I would like to hear different opinions regarding Brake rotors.

IPD has 3 different types including Brembo available.

My local part shop also has OEM for $50 each

Why should I pay for IPD $84.50 when my local part store has them for $50?

I have not increased the performance and most likely will not so cannot see the benefit of Drilled or slotted rotors.

What would you do ?

If it's a pure street car you don't need slotted, and cross drilled is a waste. Whatever you buy I'd stay with Canadian or US made....no Chinese crap.

I used one of the high performance discs off rockauto. I dont remember which ones they were, but they were poweder coated black on the hat and in between the layers. I didnt get drilled or slotted. matched them with the hawk HPS pads and i dont have any complaints. Im not too sure what the differences are between OEM and cheap aftermarket ones are though, besides the angled cooling vents. If the disc thickness and size are the same I cant see how much of a change it would be..

My experience with the cheaper priced auto parts store rotors is they are thinner metal - you can feel the weight difference when holding one in your hand vs. a premium version from the same store.

If they are made offshore, who knows what the metal is made of and if they have any hardness treating and if so, how deep that is into the metal surface.

Volvo Brand is a quality Rotor made by textar. Brembo blanks are garbage.

If you can buy Textar Coated Rotors for $50 since they are the same as Volvo OES.

I always thought that brembo made the rotors.

Were can you find textar coated rotors for that price?

I don't know if this applies to the R rotors or not, but a few months ago I bought Volvo rotors from Tasca for my Dad's S70... they are now made in China.:angryfire:

Drilled and Slotted Centric Blanks....Little Chinese gentleman behind a CNC machine doing the drilling and slotting....Now technically, this is made in USA...butttt....

I have been running on a set of PowerSlot slotted rotors for 50k miles with multiple track days and no brake fade or warped rotors (I brake hard and I am in the gold caliper club).
Still planty of life left on the rotors.
It kills brake pads tho.

But if you are just daily drive your car Brembo blanks are fine.

From what I've gathered, there are very few if any companies that actually use USA steel.

Many will start with foreign blanks and machine them in the USA or other countries, then claim they are "manufactured" there.

As for arguing which is better, it comes down to what you can justify spending money on. Cheaper rotors are just that, cheaper to replace when you crack them or wear them too thin. I highly doubt any of you will crack your rotors on the street either. I'd like to see Fishey comment again in here as you guys tend to get carried away on this topic.

As for my actual recommendation: Centric High Carbon rotors and the pad of your choosing. Hawk HPS is nice for a slightly more aggressive pad, still not track ready or anything, but typically handle a little more heat than factory spec pads.

j-velocity
Brake fade would be a product of your pads, not the rotors. It's also very common for the rotor to crack from heat stress rather than to warp. Which pads are you using?

DRT is a quality operation and product. I ran rotors from DRT for over 80K. Drilled and slotted.

^No doubt about that, but Volvo rotors were historically made in the EU (Poland or France IIRC) and they've always been highly regarded as quality rotors. Not so much so that they're now made in China.

Not to get into another argument about China vs. the world...

Drilled and/or slotted rotors are over-kill for a street-only daily driver. They may look good but you won't notice anything beyond that. I'm second Vovo's sentiment in that the powder coated hat on the StopTech rotors was a big selling point for me. The hats on the OEM rotors that were on my car when I bought it convinced me that a powder coated hat was the way to go. Avoid rust and corrosion.
