Are these rotors ok for DD / street & race ?
We believe that for the typical Hellcat driver that there will not be any issue with DD.
With that said, we have seen Hellcats with rustic wraps, mud tires and literally being driven in the sand off-road. We've seen Charger HCs doing donuts in 12" of snow in elevated parking lots, and even a Demon doing 0-60 videos in the snow as well (much love). So with that said, if this is someone's choice of driving, CDT Rotors might not be the best choice for those owners.
In design there is always give and take, and if CDT gave up something, it was tolerance for exposure to extreme debris.
Look at the vents in the O.E. rotor, you could pass a truck through there. There are two reasons for this, mass and, in our view, a silly need to accept debris that cars like this never (almost) see.
Many Hellcat owners don't let their cars see rain, nevermind mud, gravel, sand or salt.
Our rotors are specifically designed for, and intended for performance driving, whether it be 1320' at a time, or road courses.
When you see the actual design for the first time, we think you'll be impressed and you'll understand.
