Like many, money is tight right now. My Brembo blank rotors had about 30K miles and they were a bit out of spec in terms of wear. About two years ago, the Tirerack was selling the Brembos for about $75/ea. Now they're $109/ea which is about most dealerships will charge for OEM rotors. I saw that Tirerack has a replacement rotor called Cryo-stop made by Centric. They're $74/ea and cryogenically treated supposedly to improve rotor life. The rotor hat and edges are painted with heavy duty black finish and the rotor faces are double ground. From my research, lots of E36/E46 BMW owners run these rotors.

I ordered a set and installed them along with new OEM pads. There is something different about these rotors because at first drive I was quite worried because braking performance was non-existent as I was driving cautiously to my "bed in" area to get these things broken in. My Brembos were nothing like this. After bedding the brakes, the performance improved quite dramatically. Over the past few days, I've noticed that they're extremely responsive and you can modulate them a bit better than the OEM or Brembo blank rotors. They're not quite as grabby at first bite (however still far more than any car I've driven), but when you push on them, they're freaking awesome. They must be ever so slightly wider because when I installed them with the new pads, the brake fluid level went a bit above "max". I've never added or removed fluid from the system which leads me to believe the rotors must be slightly wider by a hair. I had to remove just under a table spoon of brake fluid from the reservior to get it to max.

 

nice find

 

Centric premium rotors (black hat) are what Stoptech uses as a starting point, so they should be very good rotors. As for the cold bite, did you change pads too?

 

these are the $50 rotors at everything G35.. but their shipping method sux..

 

The best test for rotors is to weigh them as high quality cast iron weighs a tiny bit more, as does thicker metal vs air space, more supports in air space is good but expensive.

Everyone tries for a minimal weight solution since the freight [~20 pounds] from China or Poland [Brembo] may be a significant part of the wholesale cost.

Cyrogenic restructing of atoms is an excellant way to improve low quality cast iron after manufacture.

 

I've had excellent results with my Cryo-Stop rotors.

I've used Brembo blanks in the past, but decided to give Cryo-Stops a try and I havn't had any regrets yet.

I would order Stop-tech's for myself at work, but they don't stock blanks for my car and I lack the patience to order them

 

I've been looking around to find rotors and front brake pads. I saw these rotors on tire rack but was confused why the description lists only a "front left fitment". Since these aren't slotted or directional in anyway, I wonder why they list a specific fitment as opposed to simply "front fitment"??

 

Hey, all. I purchased the Cryo-Stop rotors (for the front) from Tire Rack. Upon opening the package and inspecting the rotors, I noticed that the small open for the "safety bolt" is not present.

Did Tire Rack send me the wrong rotors? If not, how did you guys handle this issue?

 

Assuming you're referring to the extra bolt in the hub, you don't need it. That's just there so you don't mix up the staggered wheels on the coupe - i.e. so you don't put the front wheels on the rear and vice-versa.

 

are you sure? i can't find any instance of it on everythingg35... search yields no results of cryo-stops....

05-06 sedans seem to get no love...

i ended up getting centric rotors from carstuff.com.

if they are the cryo-stop ones all the better, if not, oh well... at least they should not warp and get hotspotted like factory ones are.

 

Thanx for the info, G35fromPA. I remember the purpose of the bolt, but I was not sure if it was removable.

So, when I get the old rotors removed, there is a way to have that bolt removed? I was concerned that I would have to drill a hole into the rotor hat to accommodate for the bolt.

 

It is easily removeable with a socket wrench. I'm not even sure where my bolts are at this point...I took them off 4 years ago for when I first swapped to snow wheels/tires.
