Floating Frozen Rotors for the BMW E46 M3.

These are a semi-floating design that help disspate heat as well as reduce unsprung weight. The advantages are plenty - reduced heat transfer to hubs means better bearing life, less transfer or heat to the wheel, as well as the resistance to warping. Couple that with the benefits of Cryo Treating a rotor, and you have an excellent value. A rotor that performs better and lasts longer.

Only available Cross-Drilled. Be sure to purchase left & right sides as the cooling vanes are directional for these rotors.

Frozen rotors are NOT sold in pairs - prices listed are for one rotor. If you need both front rotors, you must buy two.

Frozen Rotors® from Diversified Cryogenics deliver increased performance and a higher level of safety while significantly reducing braking system costs. Our proprietary, 60-hour cryogenic process permanently and dramatically improves the usage life and stability of brake rotors to create a distinct advantage in tensile strength, abrasive wear resistance and rotor longevity.

Increase Performance

Frozen Rotors® resist cracking, warping and fading. By using the cryogenic process to inhibit internal oxidation and increase thermal fatigue resistance, Frozen Rotors® can last up to three times as long as untreated rotors.

Increase Safety

Frozen Rotors® provide more predictable, consistent braking–even under extreme circumstances.They are the ideal choice for high-usage and high-performance vehicles that demand reliability and safety.

Reduce Costs

By extending the life of your braking system with the exceptional durability of Frozen Rotors®, you can save thousands of dollars in brake rotor and pad replacement costs.

What does this mean for you and your car? Yes you can find cheaper rotors out there, but why bother when you'll have to change them long before you'll have to change these? Having trouble with cracking and warping? Try the frozen rotors and see if they work for you. We've used them for countless miles on track and on the street. They've proven themselves to us, and we're pretty skeptical of "miracle products."

Frozen rotors are sold individually, just as they are from the dealership. If you need two rotors, you need to buy two rotors. We stock a large number of rotors at our location, but cannot stock everything. If we don't have it, your rotors will ship the Monday following your order. It's that simple!

Frozen rotors are sold with no machining - ie: not drilled, slotted or dimpled. Unless specifically noted, those machining processes cost extra. See This link for more information.

The EBC “GD” series is signified by a “three spot” drilling pattern and a wide aperture full width slot. The full width slot expels dirt, rust, dust, grit, water and any other contaminants that may get between the pad and the disc surface. One important feature is to note that our wide aperture slots also can contain significant volumes of surface gases which are created during heavy braking and prevent the pad from “aquaplaning” on these gases, allowing the pad to contact the disc better and improve brake performance.

The three blind holes drilled in EBC’s “GD” series are to further break down gas film in between the slots but are not “through drilled” for one very special reason. 99% of all brake rotors designed and made in the world are what we call straight vaned. This means that the ventilation slots go directly from the outer edge of the rotor, towards the centre point of the disc. There is absolutely NO BENEFIT in through drilling brake rotors which do not have the vane system designed in a “scoop” fashion (which draws air through the centre core of the disc). In fact the drilling of holes through straight vaned discs can, if the holes coincide with the positioning of the vane, weaken a disc and cause catastrophic damage.

EBC Rotors are sold in pairs. So one set will cover both the left and right wheel of the front or rear of the vehicle.
