  • $2995.00

This maximum performance system is a must for serious street machines and high horsepower track cars. Utilizing a deeper hat offset this system is a direct bolt on to '65-73 Mustang DRUM or DISC spindles & '75-80 Granada spindles.  Fits 18" wheels or larger. 

Leading edge caliper mounting is required if using our SOT Billet Big Spindles.  You may also choose to use this system on factory DRUM spindles should the leading edge mounting be desired.

Offering maximum performance this system is a must for serious street machines and high horsepower track cars.  Utilizing a deeper hat offset this system is a direct bolt on to 65-73 DRUM, 68-73 DISC (OEM & TCP Spindle) & 75-80 Granada spindles.  

This complete brake system offers the highest level of performance available.  Using heavy duty directional vane 14 x 1.25" rotors that mount to an aluminum hat this system offers great weight savings and exceptional cooling.  Stress flow forged aluminum calipers with 6 stainless steel pistons accept .800" thick pads in a variety of compounds.


Differential piston bores provide even pressure along the length of the pad.  This considerably reduces or completely eliminates longitudinal pad taper.

General Specifications:
 Wheel Size Required:Fits 18" or larger wheels
Axle:Front

 

Caliper Specifications:
 Description:Forged Aluminum 6 Piston.  Radial mount, differential bore
 Type:Fixed/radial
 Number of Pistons:6 - Staggered stainless
 Piston Size:1.62", 1.12", 1.12"
 Construction:Stress flow forged from premium grade aluminum alloy billets.  This process re-aligns the metals internal grain structure to flow within the contour of the caliper body.  This process eliminates the stresses and interruptions to the internal grain structure that occur when machining a straight block.  This results in a stronger and stiffer caliper.
 Pads:Continuing the performance trend of this system, this caliper uses a huge pad that is almost as thick as a stock Mustang rotor!  Thick pads not only last a long time, they offer insulation from the heat of the rotor transmitting to the pistons and ultimately the fluid. 

Compound Information

Street:

  • Medium friction, smooth engagement, low abrasion.
  • Flat torque curve.  Maintains a coefficient of friction between .40 from cold peaking at .45 around 700F degrees.
  • Beds quickly and provides fast response without excessive abrasion.

Track:

  • High friction, smooth initial response, low wear rate.
  • Medium to high friction with good cold response.
  • Smooth, predictable engagement. 
  • Long wearing pad in the middle temperature ranges with only moderate wear in sustained high heat conditions.
  • Peak coefficient of friction of .63 is reached at only 400F degrees and is almost flat all the way to 1300F degrees.
 Finish:Powder coated bright red or gloss black - other custom colors available.
 Notes:Each caliper is equipped with replaceable stainless steel bridge plates. These plates eliminate the bridge wear caused by pad gouging and extend the service life of the caliper body. The spring-loading action of the plates also eliminates pad rattle and dampens the vibration harmonics that contribute to squeal under braking. Other standard features include high-temperature, square faced o-ring seals for positive sealing, controlled piston retraction, and long service life in high heat conditions. Stainless steel pistons are used to resist corrosion and retard heat transfer from the pads. Two-piece bleed screw assemblies provide long, reliable service life and are easily replaced if necessary. 

Caliper is mounted rearward of the spindle upright (trailing).  This position makes routing brake duct hose in from the front of the car super easy.

Use 1" bore master cylinder for perfect pedal height/pressure like #HERE.

 

Rotor Specifications:
Type:Heavy Duty 2 piece mount to CNC machined billet aluminum hats.
 Diameter:14"
 Thickness:1.25"
 Venting:36 Directionally vented vanes
 Finish:Plain or Gas vented slots
 Note:We use only quality, heavy duty castings cast and machined in North America.  Many cheaper 'offshore' rotors are poorly cast and may contain inferior materials and air pockets.
Why use such a large rotor?  Well, simply put, heat.  The friction created by braking creates heat and the more and harder you brake the more heat is generated.  All that heat has to go somewhere and if the 'heat-sink' (rotor) gets so hot it can no longer absorb and shed heat then the heat will conduct and convect to other components.  These other components will include brake fluid and wheel bearings, not places you want increased heat.  The problem with large rotors is weight.  All that weight is unsprung which will affect suspension performance and increase stopping distances.

The rotor we use in this kit provides the best of both worlds.  Increased thermal mass due to its diameter and thickness yet lighter weight when mounted to an aluminum hat.  Maximizing the size of the aluminum hat and minimizing the iron rotor ring to only the pad swept area reduces the weight of the entire rotor/hat assembly to only 15lbs 10oz's per side.  The wide air gap of this rotor promotes more airflow and sheds massive amounts of heat keeping brake temperatures in check.
