Well as you already know Lexus utilizes OEM BREMBO for the exiting IS F and a few other current Lexus Performance inspiring cars... ![Wink](https://www.clublexus.com/forums/images/smilies/wink.gif)
The RC F gets an update in the Braking Department.![Woot](https://www.clublexus.com/forums/images/smilies/woot.gif)
The Front gets a larger 6 piston caliper w/2 bridge bolts this time. Which will now bite down on larger 380 mm rotors.. UP from 360 mm on the IS F..
So approx. from 14.2 inches to 15 inches
![Thumb Up](https://www.clublexus.com/forums/images/smilies/thumbsup.gif)
The Rear also gets a larger, now 4 piston caliper (up from 2), which will still bite down on 345 mm. Same size as IS F. (13.6 inches)
This time around Lexus will still have the one piece ventilated rotors, but they are Not drilled..
They will be curve slotted..
They will also have proper L & R directional part # numbers as well.. (Was not for the IS F)
These pretty much match the specs of the aftermarket Brembo GT kits..
Minus the caliper solid bridge designs and two piece floatting rotors..![Wink](https://www.clublexus.com/forums/images/smilies/wink.gif)
Enjoy,

It's a great direction and technology has immensely increased over the last 7 years for Brembo.
The drilled IS F ones will often crack after repetitive abuse on multiple track days..
I'm sure they also implemented their improved Pillar Fin design into these as well.
Not bad at all for an OEM application.

look back to f1 history before carbon brakes?
bottom line, the more surface area, the more friction. the more metal (ie no drill no slot), the more heat conducting. there is just no solid proof or evidence that drilled or slotted rotors help on heat dissipation vs performance loss / cracking
but i do admit it looks much cooler and nicer

Hopefully, that puts the issue to bed.
