Caliper Highlights:
Wilwood's new Forged Narrow Mount Dynalite
(FNDL) calipers are ideal for many competition
applications including late models, modifieds,
sprints, off road and road racing. Computer
generated design and stress analysis technology, is
the latest innovation from Wilwood providing
substantial improvements in strength and
performance over all comparable caliper models.
Forged Narrow Mount Dynalites are the strongest
calipers in the class. The process of stress-flow forging
re-aligns the metal's grain structure within the contour of
the caliper body. This process eliminates the breaks and
interruptions to the internal grain structure that occur when
machining a straight billet block. The FEA generated radial
transition design eliminates steps and shoulders in the area between the piston
housing body and the caliper bridges. Incorporating a radius in this transition area
substantially increases resistance to deflection and caliper separation under load. Structural deflection and
volume displacement tests have proven the Forged Narrow Mount Dynalite to outperform all existing styles of this
popular caliper size. Without even considering the overall greater strength and reliability of the forging, the reduced
deflection tendencies and the resulting decrease in fluid volume displacement translate to increased clamping
efficiency with less pedal travel. The bottom line is a taller pedal and better stopping power. The superior strength
of this innovative design is combined with proven performance features from Wilwood's earlier designs. Each caliper
is equipped with Wilwood's SRS stainless steel bridge plates. The SRS plates eliminate the bridge wear caused by
pad gouging and extend the service life of the caliper body. The spring-loading action of the SRS plates also
eliminates pad rattle and dampens the vibration harmonics that contribute to squeal under braking. Other standard
Wilwood features include high temperature seals and stainless steel pistons to eliminate corrosion and retard heat
transfer from the pads. Internal fluid passages eliminate the need for external tubes. Four corner bleed screws
assure simple and effective air evacuation from the system and allow one caliper to be mounted in any front, rear,
right, or left position. To round out the package, FNDL calipers are finished in black anodize for long lasting
protection in high heat environments. Polished units are also available in select piston sizes and rotor widths.
FNDL calipers are a direct replacement for all previous Wilwood NDL’s and similar competitive brands with 3.50"
centered mounting tabs. A total of five bolts provide superior bridge strength and positive retention of the top loaded
7816 or 7216 type brake pads. The full range of PolyMatrix pad compounds are available to match the brake
response and heat range requirements of any competition application.
