Frozen Rotors

[run.exe]

In approximately 2 weeks' time, I will have received my cryo-treated, gas-slotted, and nickel-washed rotors from Frozen Rotors.

I have decided NOT to run cross-drilled rotors, anymore, given the non-zero (cracking) risks, therewith.

Considering the purported (2x-5X) life-span increase of cryo-treatment, these (OEM) rotors should tide me over for 2+ years until I upgrade to a Brembo, Alcon, Porsche, or RENNtech big brake-kit.

I have ordered my Porterfield pads, too; they should arrive (from SoCal) NLT FRI 06JUN03.

Safety is NO accident! / STOP - in the name of l(ust)! / FREEZE!!!

(etc. / ad nauseam)

love the funky ass posts :P

Pics? In the name of sanity.

Kewl...pics to come i hope.


Remember this old slogan...


If speed kills......do brakes give life?

I love it...witty yet to the point.

YOu should like the frozen rotors but break in of pads is very important.. you should get 30% more out of it.. depending how hard you mash them.. in my mind they are the number one choice for rotors. Crossdrilled look sweet but the slotted is so much better for venting etc.. show us the photos.........

i don't know what the big negative hype about cross-drilled or slotted rotors is?! i mean, a lot of people complain and are afraid of cruching the rotors, but if your ride is for everyday use and if you do not go track racing every other day/week, then why worry so much? it'll be ok.

if not, disprove my opinion!

Your right..but if it's for eveyday driving..do you really need x-drilled rotors to begin with?

Touche! :D

From a techincal stand point, the slotted do a better job at getting rid of gasses than Cross Drilled ones.. Cross drilled to me is for looks only.. my 2 cents.. if I was to build a race car, German, it would have frozen slotted ones on it.. without a doubt.

Scott,

Per our conversation:

Front Mercedes factory rotors with Cryo $105.95 each
Rear " " " " " $119.45 each
Slotting (4) rotors 5 X 3 pinwheel $180.00
Estimate freight 4 day UPS ground $ 50.00 + or - $5 ? (we do not yet know the rotor weights) / (2-3 day FedEx add $30 to $40)

Total: $680.80

We will ship to you 5-10 days from the order date. Rotors not in stock at MBZ will incur a 2-3 day delivery delay from the dealer.

We run the Cryogenic Processor from Friday to Sunday (50 hour process) and ship orders on Mondays.


There are other rotors from Brembo, Centric or Raybestos - but none of the three catalogues agree on the VIN# cut-off for the SL600 upgraded front rotors - so MBZ factory rotors are the safest bet.

Cheers,

Bill Groschen

Cross drilled are also done for weight reduction.

Like everyone says, no worries if it's street driving only.

not much weight lost....and you do lose some braking surface, the best is a rotor that has just 2 or 3 slots in it so gas can escape while keeping as much surface as possible. kinda a waste to get 14" rotors that onyl have as much surface as a 12" rotor ;)

*sigh*

weird white boys.... :o

Yes it's very little mass reduction, but it's unsprung mass reduction which is "a good thing" (tribute to Martha Stewart).

Surface area is important but its effectiveness is greatly affected by brake torque. Brake torque is the force exerted by the caliper multiplied by the radius of the rotor. There is however a balance between brake torque and too much mass (size of rotor) so that's why you don't see 18" rotors. Therefore if you take a 14" rotors (cross-drilled) then you should effectively outperform the 12" even if your assessment of the total surface area is true (don't feel like counting holes and doing math :P). This is when we start talking about the calipers (what and how many).

Another issue is that the other components of the braking system is usually overcomed before the full potential of the friction (pad and rotor) is ever achieved on +14" rotors. Usually this is the failure of tire adhesion before the maximum friction is attained at the rotor.

All science aside...the large rotors just look so "pretty" :D
