Bony, just thought I would take you up on your offer and post my reply from the other brake discussion thread.Thanks Bill,
I invite Stillen and Alex to comment if they so desire...
Also Mark to post on this subject...
I hope you don't mind but I would like to offer another opinion on this subject.
There is definitely room to improve the braking system for the Ford GT. The Brembo caliper used is the F40/F50 caliper that has been around for the past 20 years. It is the best street/O.E.M caliper that Brembo offers but it can definitely be improved upon. As many people have found out it is the same caliper used by Mitsubishi, Nissan, and pretty much every Brembo brake upgrade for street cars.
When developing our GT for the Targa rally we upgraded to AP Racing brakes. We use 2-piece cross-drilled/slotted floating rotors with 6 piston AP Racing calipers. The rotor is slightly larger than the factory rotor (limited by wheel selection) but allows for better cooling and lighter weight. With the extra clamping points (2 extra pistons) in the 6 piston AP Racing caliper we are also able to increase the pressure applied. Thus slowing the car down even more.
AP Racing is actually owned by Brembo but it is the top tier division of Brembo. Some of the cars using AP Racing brakes are the Bugatti Veyron, Aston Martin, Konigsegg, and Lotus. AP is also on most Formula one cars, NASCAR, Champ and Indy cars and even World Rally Championship cars.
The factory brakes are good, as proved by Heffner Performance in the 0-200-0 test. But, there is definitely room for improvement. When Camillo Pardo was out in California for the Ford GT Rally we let him drive our orange car. His exact words were "Holy sh!t, these brakes are incredible! These are the brakes that should have come on this car."
Adding a little bit more to this...
So far we have quite a few customers using the AP front kit with no problems at all. Most of the cars that have been equipped with our kit spend a lot of time on race tracks. So far I have not had any negative feedback regarding the kit.
We have a few more products that we will be testing soon and they will require track testing. During this time we will be putting the AP brakes through more testing. I plan on inviting Cobra or Bony to one of these test sessions. That way we can have an unbiased opinion of how well they perform.
