Thread: Cobra Brake Rotors

  1. #11
    Here's the rotors I have. https://www.girodisc.com/Rotors_c_1048.html

    Those with Cobra calipers and good fluid had been a good stop gap to not spending 2400 on the fancy calipers and am not giving up performance over the fancy stuff I don't think.

    No doubt I don't think the Stoptech's are making anyone win that would not win with the Cobra brakes. I will tell you that once you own Stoptech brakes you will never own a car without them. I bought new rings after four years not because they were worn out but because I was afraid to try anymore. Hell they may have gone another two years.
    I looked at purchasing a newly built car (Mustang built to the exact specs as Aarons) that has not raced yet and I really wanted it but the brakes were not Stoptech. I was told "but they are just as good". This one thing made me walk away. Having to add the brakes I wanted put the cost out of reach. I will never own a road race car without Stoptech brakes (or some of the other high end systems). Pads are almost twice as thick and cost half what the Cobra pads cost. Brakes are something I don't ever worry about. I bleed a little fluid (ATE Superblue) out prior to Hallett then never touch it the rest of the season. If a brake duct hose get torn or ripped off we usually don't even worry about it until prep for the next event. I hate the price and I'm not sure they should be legal on a CMC car but it sure is nice to not even think about having brake issues. I think everyone running the $2400.00 brakes will agree.

I have ducts (but not good ones). The pimpy 2 piece rotors do make a difference.
    2-3 weekends?

    Thanks everyone. I have a good bit to think about now.

    2-3 seasons -- I need to replace the rings now as one has a large crack.

    When I used the Cobra setup I had to replace rotors and pads every 2-3 weekends as well.

    I would also get 2-3 weekends out of a set of rotors and pads with the Cobra setup.
    With Stoptechs I replace rings every 3 years as preventative, I have never had a ring failure. Pads I usually get 5-6 events / set.
    The peace of mind for safety with not cracking rotors and boiling fluid is great!!

    Daniel's setup with good rings looks like a nice alternative to Stoptechs.
    Another alternative would be if you could find someone parting out their car and selling their brakes. The Stoptech calipers seem to last for a very long time. I have had mine for 8 years and about 40-45 events with no issue.

    Granted it was a brake line failure, but losing brakes is damn scary.

    This is a no brainer for me. Thanks!

    Someone sent me this last year right before I went to cota. Like I did not have enough to think about the first time.
