Brembo Rotor Upgrade Experience
Brembo Rotor Upgrade Experience
One of our customers recently ordered the Brembo Iron Tyoe III Rotor Conversion with Performance Friction Brake Pads for his 997 GT3 and we thought his experience, questions, and pictures would be good for others to reference. Once this customer recieved his Rotors, he noticed that the hardware seemed loose. This was the customer's question to our sales guy.
"The Brembo rotors and PFC brake pads installed fine. One question on the rotors. I noticed that some of the hardware that secure the discs to the aluminum hats appear to be “loose”, but a printed sheet in each shipping carton said not to tighten the hardware. Were the rotors assembled by Brembo? Attached are several photos to show that the hardware appears to be tightened a different amount depending on the location of the fastener on the hat. I don’t want to run the car at track speeds if the rotor hardware is installed incorrectly. Is the brake torque on the discs carried by the fastener hardware?"
This is question is more common than one would think. We reached out to our friends at Brembo to see what the exact protocol is and what a good explanation for our customer would be. Here was his response,"Do NOT to touch those bolts! That is the way they are supposed to be. Here is a paragraph from the FAQ section on our www.racetechnologies.com web site: Some of the bushings in the two-piece disc assembly seem to be loose."
"The two-piece disc assemblies utilize a floating disc. The mounting system of the disc is designed to allow a specific amount of float in both the radial and axial directions. Brembo has engineered special springs that are used on every other fastener in order to slightly preload the assembly. This has been done to prevent excessive noise from the system during street use, while still maintaining the benefits of a floating disc. These springs can be seen when looking at the backside of the disc. The small screws on the backside of the disc are properly torqued during assembly and utilize thread lock compound to prevent loosening. They must not be tightened further."
This a great lesson for anyone new to Brembo or those who are trying their hand out at the two-piece rotor set. If you have any question about a fitment or install, call or email our sales office!

Thanks for clearing that up. Very important topic as I'm sure many people who switch to two piece rotors would be concerned if they noticed that. As far as the GT3 pictured, the wheels are Fiskse FM10 and I agree it does have a great set of mods.

Haven't heard any clicking from mine, but the car spends all its time at WOT or hard on the brakes. Usually the dreaded noise associated with floating rotors is a howl or groan from the disc going into occilation, which I've not had.
Good luck with your search

I've got these on the front and do hear the same slight ticking noise when driving near a wall. Can only hear it when the windows are down and from the side of the car closest to the wall. No complaints though.
