I did not go for the rear setup, as I did not want to lose the parking brake...
To be clear though,... This setup is still untested.
I tracked 10/10 my '17 on stock wheels/F1s with Motul 600, Hawk DTC 60's on front with zero fade all day. Stock rears. 5 20 min sessions, 2 mile course, 9 turns.
Ok. Yesterday was my track event at Laguna Seca, which is the same track that I have been visiting and experiencing braking issues. Temps started out cloudy in the 60s and moved into sunny low 70s.
I can positively report back that I had zero brake issues yesterday with the Rotora setup.
The only prep work was that I changed from street pads to their race pads in the front, and the rear I changed from stock street pads to XP10s. Changing the rears took MUCH longer than the fronts, as the fronts have a bridge bolt that you remove, and the pads come right out (very nice).
I ran 4 full sessions (well almost 4 as I blew my charge pipe about 15min into the 4th session).
I will bleed the brakes this weekend to see if there are any signs of boiling, but I am guessing that there will not be. These things were simply amazing. I had so much brake, and it was a HUGE relief not having to worry about my pedal going into T2.
The BBK is the Rotora Super Challenge kit.
Now I just need better tires (ran Bridgestone RE760 sports in 255/35).
Another route is 2 pc rotors in stock thickness, and the Brembo calipers, but replace the OEM Aluminum pistons with Stainless pistons from Racing Brake. (this option was not available until after I acquired the Rotora BBK).
