Expert Buying Guide for 1999 Subaru Impreza
For your 1999 Subaru Impreza, the bolt pattern is 5x100 with a center bore of 56.1mm. When installing aftermarket wheels, hub-centric rings are essential to match the bore and prevent vibrations. The factory offset is 55mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always use lug nuts with the correct thread pitch (12x1.25) and seat type (cone or ball) to ensure proper clamping force. Re-torque after 50-100 miles to maintain safety.
