    Couldn't locate the parts for 2013 Civic Si Sedan. Front struts are an Anomaly found them at Capital autoparts. Great service and great parts. Shipping by CanPar sucked however

  • July 2026

    Great customer service. I placed an order for wheels and tires and it was an easy transaction. Make sure you read the expected lead times for delivery however. I misread that part, but the order did arrive in the correct timeframe stated. The Hostile rims and Hercules tires look great. Thank you
