6 Piston calipers and 14" rotors!

Nobody ever steps out of my car and complains that the brakes are too good!

Just like horsepower, I don't believe you can ever have too much. Wanting to push the envelope even more I wanted to see how much rotor and what size caliper I could stuff under a 17" wheel. Turns out quite a lot!

I had my foundry whip me up a 14" rotor based off the same 1.25" wide one we use in our 13" system. This new rotor fits to the same aluminum hat which saves us weight and sets the massive caliper inboard enough so pretty much all wheels clear axially. At only 12oz's heavier than our 13" rotor this is good news as the extra mechanical leverage is certainly felt through the pedal. The brake package is extremely stiff giving great pedal feedback and good modulation.

The caliper is a monster. Its 11.25" long! The 6 stainless pistons are in what is called a 'staggered bore' arrangement. What this means is that the leading edge pistons are smaller than the trailing edge piston. This practically eliminates longitudinal pad taper wear.

Our mounting brackets are a work of art. My CAD guy spent ages putting these together and after a few revisions with our engineer we have some beautiful and very strong pieces.

The caliper is radial mount so we Loctite ARP studs into the intermediate bracket for the caliper to slide on, then ARP 12pt nuts hold it in place.

We also have brackets available for the '68-73 DISC spindle.

Just had a customer go through the upgrade path from our 13", 4 piston system to this new 14", 6 piston.

We designed the system to incorporate the same large offset hat so the new giant 6 piston caliper clears most wheel spokes. It also shares the same hubs and most of the caliper mounting brackets. Sharing parts helps us keep the retail costs down and enables customers an upgrade path if they wish.

14", 6 piston system fitted. The upgrade includes the 14" rotors, 6 piston calipers and the new radial mount bracket and hardware:
