These kits feature either the FDLI or FDL M four piston forged aluminum calipers and 11. 00 to 11. 88" diameter one piece rotors. The FDL M caliper is a modified version of the time tested Forged Dynalite caliper, and provides the greatest amount of wheel clearance of any four piston caliper in its size class. The OEM style one piece cast iron rotors with integrated hubs simplify installation while providing superb dimensional stability and wear resistance. These versatile kits are easily optioned to suit the braking requirements and style preferences for a daily driver or the most discriminating show enthusiast. Intended vehicle applications require no modifications for installation, and clear most 14" or 15" OEM or aftermarket disc brake wheels. Kits generally will not fit OEM drum brake wheels. Classic Series FDL M kits can be used with either manual or power boost master cylinders, and come complete with calipers, rotors, brackets, hardware and detailed installation instructions.
