Caliper Spacer Metric .100 Thick

The Caliper Spacer Metric .100 Thick by Allstar Performance is an essential precision component for brake system customization and performance suspension work. This spacer addresses a critical need in brake caliper alignment when modifying suspension geometry, installing larger diameter rotors, or running aftermarket brake packages that require rotor offset adjustment. Whether you're building a track-focused platform or fine-tuning OEM brake geometry on a modified street vehicle, the correct caliper spacing ensures pad-to-rotor centering and prevents premature wear or binding.

Manufactured to exacting tolerances, the .100-inch thickness of this metric spacer allows precise caliper offset when standard brake hardware no longer provides proper rotor clearance. The 5.5-inch length accommodates most metric brake caliper bolt patterns found on import and European chassis. As a shim-style component, it installs between the caliper mounting bracket and the steering knuckle or spindle, maintaining consistent brake line pressure distribution while correcting misalignment caused by suspension modifications. The lightweight 0.17-pound design ensures no additional unsprung mass while delivering years of reliable service in both street and circuit applications.

This metric caliper spacer is ideal for technicians and enthusiasts upgrading multi-piston brake systems, lowering springs, or radius arm configurations where factory caliper mounting holes no longer align with rotor centerlines. Installation requires removing the caliper assembly and positioning the spacer between mounting surfaces before reinstalling hardware to factory torque specifications. Verify your specific brake caliper pattern and rotor diameter before purchase to ensure compatibility with your suspension geometry and brake package configuration.
