The Forged Narrow Superlite6R Dust Seal (FNSL6R-DS) is our newest version for the venerable Superlite caliper series adds the versatility and convenience of radial mounting to this widely popular caliper group. Radial mounting simplifies adaptationand provides two planes of adjustment for accurate alignment over the disc. The addition of Wilwood’s exclusive wiper dust seal allows these calipers to be used in areas that may mandateenvironmental sealing. These calipers integrate "Big Brake" style with Wilwood's latest technology togenerate big stopping power inextreme environments over a broad range of vehicle applications.

The key tothe superior performance of the FNSL6R-DS comes from the extremely durable and efficient body design. Starting at 4.9 pounds it is the product of computer generated solid modeling and FEA stress analysis technology. The most noteworthy feature of this newcaliper design is the forging.Each body is stress-flow forged from premium grade aluminum alloy billets. Stress-flow forging re-aligns the metal's 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 billet. Simply stated, there is no better wayto build a stronger aluminum caliper body.

A unique six-piston differential bore configuration provides balanced loading for even pad wear in sustained high heat environments. The standard FNSL6R-DS calipers feature one-piece stainless steel pistons. Stainless is used forits slow heat transfer properties and high resistanceto corrosion. Calipers can be upgraded with Wilwood's exclusive Thermlock pistons. This multi-part piston design creates a highly efficient thermal barrier to further reduce heat transfer from the pads to caliper body, seals, and fluid. Cooler temperaturestranslate to longer service life and less chance for heat induced pedal fade.

In addition, each FNSL6R is equipped with SRS bridge plates. SRS plates eliminate all bridge wear caused by pad gouging and extend the servicelife of the caliper. The spring-loaded action of the SRS plates also eliminates padrattle and dampens the harmonic vibrations that contribute to pad squeal. Two piece bleed screws on each endand internal fluid crossovers prevent damage from track debris and other potential damage sources. High temperature, square faced boreseals provide the largest possible sealing area and controlled piston retraction on release. The full range of Wilwood pad compounds is available to match the brake response and heat range of anycompetition or sports driving application.
