Expert Buying Guide for 1998 Audi Cabriolet
For your 1998 Audi Cabriolet, the 5x112 bolt pattern and 57.1mm center bore are critical. Aftermarket wheels often have a larger bore (e.g., 66.6mm), requiring hub-centric rings to prevent vibration and ensure proper load transfer. Offset is sensitive: stock is 45mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always use correct lug nuts: 14x1.5 thread pitch with a ball seat (OEM) or cone seat (aftermarket). Mixing seat types can lead to loose wheels. Re-torque after 50-100 miles. Avoid spacers without extended studs.
