Expert Buying Guide for 1997 GMC Sonoma Club Coupe Cab
For your 1997 GMC Sonoma Club Coupe Cab, the 5x120.65mm bolt pattern is shared with 1993–1998 models. The 70.3mm center bore is critical: aftermarket wheels with a larger bore require hub-centric rings to prevent vibration and ensure proper load transfer. Offset must stay within 0–13mm; deviating can cause rubbing or clearance issues. Always use 12x1.5 lug nuts with the correct seat (cone or ball) matching the wheel—mixing seats leads to loosening. Re-torque after 50–100 miles. Avoid spacers unless hub-centric and verified for strength.
