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

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
