    Hi all,
    Recently picked up my challenger hellcat and am booking a track day in sept at limerock in Connecticut. The director suggested I check brake fluid and possibly flush it prior to track day and put in better fluid if necessary. Does anyone know what dot level it comes stock with. And do you recommend flushing and upgrading the fluid prior? Any help would be great. Thanks

    Dot 3 factory I'd use Dot 4 when you do

    Thanks for input. Track director said DOT 4 is required especially if it's a hot day

    Although DOT4 fluid is preferred for road racing because of it's higher boiling point, one must also be aware that it is more hygroscopic than DOT3 and therefore, needs to be flushed more often.

    You will want to swap out the fluid for a higher temp fluid, I have used ATE Blue, which subsequently was outlawed by the dot due to blue dye...

    Wilwood 570 or 600
    Motul 600
    Are also great choices

    The stock fluid is great for general driving but has a much lower boiling point, so on the track if you push it hard for multiple sessions you will heat it up and experience fade.

    Wow lot of info here...thanks again guys...so I'm thinking maybe I'll flush and replace with the Torque prior to track day, and then after...I'll probably need new pads by then anyway, go back to the DOT 3...
    any recommendation for new pads that dont produce so much brake dust?

    Torque is just my preference do your research to see what you decide. I've ran most (and tested a couple) in my multistrada GT (never did analysis in cars but I feel would prove same.) That bike is horrible on brake fluids because in Ducati's infinite wisdom, they placed the rear brake master cylinder too close to the catalytic converter, so the heat fluid is exposed too is very high. When I did last analysis the Torque had about 1/2 the water compared to Castrol SRF (and Castrol should be shot for what that fluid costs.)

    Careful with pads that claim less dust, it usually means they are such a hard material (like ceramic) that they have less friction and have bad fade performance. Leave the ceramic for making coffee mugs.
