Just eye candy. I realized I have not previously published any visual of that new combo on the Race kit. So, I quickly assembled the new aluminum hats and stainless steel drive-pins with an old worn rotor. The floating allows indepenent expansion of the stel rotor and aluminum hats, which expand at different rates and different temps. Le lateral float is a slip-fit with minimal play. No noise. The extra width of the air gap allows for improved cooling compared to a 21mm disc. More air go thru the vanes, more heat gets evacuated, and less of that heat gets transmitted to the caliper's pistons, and fluid.
