Based on the venerable forged billet Dynalite caliper, these versatile kits are easily optioned to suit the braking requirements and style preferences for a daily driver, serious competition, or the most discriminating show enthusiast. Most vehicle applications require no modifications for installation, and provide plenty of clearance inside popular 15" wheels. FDL Pro-Series kits can be used with either manual or power boost master cylinders. Kits come complete callipers, rotors, hub assembly, brackets and hardware.
