Recent purchased new Hawk HPS brakes for my 2010 Hyundai Genesis Coupe 3.8 Track.

The order was processed quickly, packaged very well, and was the correct items I had ordered.

Not only did I experiece great customer service and quick shipping/processing, Autoplicity also had the LOWEST price of any vendors for these parts I could find online.

Great service + Great pricing = Match made in heaven!
