Fitment & Compatibility

Use the fitment table below to confirm year/submodel for your 914. If you’re rebuilding both rear calipers, order one kit per side.

If you have questions about rebuild parts, core condition, or whether your calipers are original to the car, send us your VIN and what you’re seeing. We’ve been doing Porsche brake work for over 20 years, and we still treat fitment questions like they matter—because they do.
