Fitment & Compatibility
The confirmed applications are 1995–1999 BMW M3 E36 and 1998–2001 Z3 M Roadster with the 3.2-liter engine. This is not a general Z3 kit. Retain the original hubs and verify the factory spindle and brake configuration against the exact model entry.
Use DS495 to check bracket seating, caliper alignment and wheel clearance. Separate hose kit 220-8799 supplies the Wilwood-compatible hydraulic connections. The hat-hole clearance specification does not change the BMW hub bolt pattern.
Review the complete fitment table below before purchase, retaining the restrictions attached to the chosen vehicle.
