    Brake fluid for track use

    Ok.... so I’ve got most of the parts assembled for the 11 inch swap on my 84 Laser XE. What Hi Temp brake Fluid is everyone using? Put Motul 600 in the wife’s Miata that she does track days in but the laser is heavier and I expect higher brake temps. Just wondering what people who track their cars use. Also front rotors, solid? Or dimpled?

    In my CSX I have run the following brake fluid
    https://smile.amazon.com/gp/product/...?ie=UTF8&psc=1

    I had no problems the last time I did a track day as a result of brakes. The pedal never lost any feel, and the pads performed well too. I have 11" brakes all the way around on that car with drilled rotors on it and Hawk pads for the front. I have had very good success with the 11" brakes in the front of cars and find that solid rotors do just as well for me. I think most of our lighter cars don't have the weight to make the 11" brakes strain if they're properly maintained.

    IIRC, Team Shelby used 11" brakes and had great success with them during endurance events. I seem to recall they were able to make up a lot of time when they swapped over to them because they only needed to change them once a race or something along those lines.

    Just as an FYI, Tirerack had a good deal on the Type 200 fluid. It was $17.xx with free shipping if you picked up over $50 worth.

    I'm using this as well. I'd say it worked well, but I had brake fade at high speeds during a road course event after some time (< 10 minutes). I am still running the stock MC with larger brakes, so I can't fault the fluid just yet and my turbo sits right next to the MC.

    I didn't realize you were using the smaller MC still. I bet you were using all the pedal travel you had when the brakes got soft on you.

    I know I need to replace it, but I heard guys locking up the rears, so I would need to put in either a different proportioning valve or a manual one to set it so that doesn't happen. I mean I think the rear brakes I have on the car are the same size as the standard rear swapped brakes, probably?

    That's a good question. Put on some Viper brakes and you won't have to worry about locking the rears up any longer if I had to guess. That would be way more front bias from my wild guess.
