Superlite 6R Forged Narrow Radial Mount Caliper
The Forged Narrow Superlite 6R (FNSL6R) is our newest generation of the venerable Superlite caliper series. It adds the versatility and convenience of radial mounting to this popular caliper group. Radial mounting simplifies adaptation and provides two planes of adjustment for precise alignment over the rotor. These calipers integrate big brake style with Wilwood’s latest technology for high-performance stopping power in extreme environments and a wide range of vehicles.
The key to the FNSL6R’s superior performance is its exceedingly durable and efficient body design. Beginning at a 4.9 pound starting weight, it is the product of computer generated solid modeling and FEA stress analysis technology.
The most significant feature of this new caliper design is the forging. Each body is stress-flow forged through the application of hydraulic pressure into a die in the shape of the caliper from a premium grade aluminum alloy billet. This process realigns the internal grain structure of the metal to match the contour of the caliper body. This process eliminates the stresses and interruptions in the internal grain structure that occur when machining a straight block of billet. In short, there is no better way to build a stronger aluminum caliper body. A unique differential bore six-piston configuration provides balanced loading for even pad wear in sustained high-temperature environments. Standard FNSL6R calipers feature one-piece stainless steel pistons. Stainless is used for its low heat transfer properties and high resistance to corrosion. Calipers can be upgraded with Wilwood’s exclusive Thermlock pistons. This multi-piece piston design creates a highly efficient thermal barrier to further reduce heat transfer from the pads into the caliper body, seals, and fluid. Lower temperatures translate into longer service life and reduced chances of pedal fade due to heat.Rotor Dimensions
