Note for Pistons, Rings, Rotors, Rods and engine internals
Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only.

Brake Caliper, Forged Dynalite Internal, 4-Piston, Aluminum, Black Powdercoat, 0.38 in. Rotor, Front or Rear, Each
Wilwood Forged Dynalite Internal calipers are the next generation enhancement of the venerable Forged Dynalite series and feature a single split bridge and spacer-less design to enhance strength and appearance. These latest applied developments and innovations in the caliper's design and manufacturing processes have resulted in substantial improvements in strength and performance over all comparable models. Wilwood's Forged Dynalite Series calipers are the strongest in the class, with weights starting at 3.00 pounds. The process of stress-flow forging re-aligns the metal's grain structure within the contour of the caliper body to help eliminate the breaks and interruptions to the internal grain structure that occur when machining a straight block billet. The FEA generated radial transition design eliminates steps and shoulders in the area between the piston housing body and the caliper bridges. By 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 Dynalite to outperform existing styles of this popular caliper size.
