I was referred to Callace Rennsport from another Porsche Specialist shop that was unable to diagnose my car. The team at Callace immediately knew what the potential problem was and had the knowledge and expertise to proceed. My 981 Cayman ended up needing a new PDK unit as well as a few other maintenance parts that Callace was quick to bring to my attention. The Callace team was very thorough in their diagnosis and procedures as they worked diligently to procure the necessary parts. Overall, I would like to thank David, the service manager, who was really knowledgable and helped to streamline the whole process. Thanks to JT, the tech who worked his wizardry. The owner, Tony, took the time to introduce himself and thank me personally for bringing the car in to Callace Rennsport for the repairs. And it's the cleanest most oraganized shop you've ever seen! Thanks again!
