We now have a new high quality brake rotor available from RacingBrake based right here in NJ. I met with them today to check out there facility, and staff. It is a great operation with very high quality Brake Rotors. They have a full line of brake rotors available for many cars including the Mini. There brakes are not just OE Brakes slotted and drilled, but a high quality Cast Rotor, Balanced, and Surfaced to exact specifications - much higher then all other rotors on the market.

This is the same design as used in the Mini Brakes, but a stock photo of a 5 lug setup


Cost per set is Regularly 225 front, and 195 rear. To help bring these new rotors to market, and build up a great name We are offering at the introductory rate of 205 for the front and 175 for the rear.

We will have stock tomorrow morning and will be shipping right away. As they are local to us, we can guarentee that we will be able to ship quickly buth from our stock, and the ability to pick up the same day!

If you need some more info please send me an e-mail, dan@piloracing.com

 

Forgot to mention, they are available here.

Can't tell from the photo... are they cad plated?

 

they are not CAD Plated but EPD Coated.

"high performance rotors are precision machined and balanced to industry leading specifications for excellent performance.

Cast from engineered iron alloy for strength, durability and performance.

Double disc ground and balanced after drilling and slotting for smooth operation.

Drilled and slotted to run cooler and vent gasses.

Finished in black by an EDP (Electro-Deposition Paint) process that resists corrosion."

For more info please check out the Rotor Comparison Matrix

 

Rotors are now in stock ready to ship. Have them on my car, They are much better quality the stock, and look really trick!!! I have a race tomorrow, so I will have some more info tomorrow.

 

Sweet, can you get pictures of the rotors on your car? This is aggressive looking. I was thinking of getting slotted rotors in the future as an upgrade but not cross drilled as I have thought they would be very expensive. Can you let me know what are some of the downsides to getting cross drilled rotors? I have heard that they make the rotor less solid, is this true? Well obviously there are holes in them but I mean from a practical stand point. I drive hard on the canyons occasionally and my brakes do start to fade when I push the car, so I'm looking around to see what change would be best for me in these situations, besides switching to a better brake fluid. Thanks!

 

Hi Dan -

what pads would you recommend with these? I'd probably do fronts only for now.

Ok here is the deal with Drilled Rotors.

The holes provide cooling for the Rotor. This is about a 40 degree diffrence under race conditions (As tested by the manufacturer.) The issue of rotor failure comes as many companies buy either OEM Rotors, or OEM Spec Aftermarket Rotors, Machine some holes into them, and sell them. This type of rotor is not made to handle the holes and cause pre-mature stress cracks and / or rotor failure.

The MAIN Diffrence between these, and others is that these are DESIGNED for the holes and the holes are a forthough, not an after thought. This is what allows them to produce such a high quality rotor that will not have the same issues that other types would. This being said, under race conditions, all rotors will wear out quicker then normal including this one. If you do some road racing, and street driving, you should not experience this. Canyon Driving and spirited driving have not caused a problem with these rotors as of yet.

Let me know if there is any thing else that you need to know, and I will do my best to answer your questions. I am trying to get all the info out as possible in an honest manned.

 

>>Hi Dan -

This depends on the type of driving that you do. Let me know, and I will try to point you in the right direction.

 

Today is the last day for this introductory price. I have done some racing on these brakes, and the really feel geat. Had stopping power, and stayed cool. After this proces will increase to the normal rates.

 

Thanks for the offer, but unfortunately it's not in the budget right now.

I have decided to continue free shipping on this product for now, until an unspecified time, but the price will be regular. I want to keep continuing to give you all the best prices around when possible.

Thanks,

Your new rotors look great, but I have a question about the design of the slots. Since the slots don't actually go out to the edge of the rotor they wouldn't seem to allow the hot gas produced at the pad/rotor interface as ready a way to exit as others I've seen that go all the way to the rotor edge. This may be minimized though since it is only in contact with the pads for, what, 1/4 of each revolution? Any thoughts you have on this are appreciated.

Also, are the holes cast into the rotors or are they drilled after casting?

Thanks, SCA

If we look at Powerslot rotors-

We see that the straight slots go all the way to the outer edge of the rotor.

>>Also, are the holes cast into the rotors or are they drilled after casting?
From the site it appears the rotors are cast with the holes. Even so the heat build up can cause even rotors with casted holes to form micro cracks- just have to check the rotors regularly.
You should avoid any rotor that was drilled after casting.

The holes are cast, and then chamfered after the process. The slots do not aid in cooling but allow a place for any gas that has built up betwee the pad and rotor to be moved out. THe hols provide the extra cooling. The guys at RacingBrake stand behind there product and have told me they have only experienced 1 rotor that had experienced cracks by the holes. That car was used for track use only, and that was the cause.

They have not had an issue with a mini as of yet. I am doing autoX, Track Events and Lots of daily driving, and have been very happy so far.

I will post installed pics later on tonight.

 

Well,

I just decided to give RacingBrake a call to better explain some of the questions asked. Great service over there. Even answered my call at 9 at night on his cell phone!!!

Well, One other reason for not running the slot to the edge of the rotor is because is causes both a thin spot as well as a sharp edge that becomes prone to heat/stress cracks. That is why RacingBrake has left a smooth rounded edge slightly in on the edge of the Slot to protect from this. (The same reason that the holes are chamfered after the fact and not left sharp.

Also, The gas does not need to evacuate the rotor at the end, but be given a place to expand and be removed from the Pad, and released when past the pad. This is the main function of the Slot.

 

Curious as to how these are still holding up. I ordered a set and installed them this last weekend. Look great, and seem to stop better everyday (as the pads get bedded), but I'm running a HPDE next month and will see how they do.

I read everywhere that cracking on drilled brakes may be an issue, but I contacted Racingbrake.com and they didn't think it would be a problem.
I admit they look to be excellent quality, and not drilled OEM rotors. I guess a track day will tell the tale...

Anyone with experiences with these rotors? BTW I got the Hawk HPS pads.

 

Rotors look GREAT! Would like to see pics on your car. Any idea where I could get these mounted to my car? Unfortunatly, at this time I am unable to do the work....I live at the Jersey Shore...

Thanks!

 

Here is a picture.

You can get them installed most places. The install is not that tough. A good mechanis should be able to handle it.
