Donnelly Racing Services LLC

Diggie at Donnelly Racing Services has been exceptional to work with. He methodically diagnosed and resolved several lingering issues on my Porsche 944 Turbo and the car is now running exactly as it should. He also completed high-quality work on my 996 Carrera 4S with the same level of precision and attention to detail. His technical knowledge, professionalism, and clear communication throughout the process gave me complete confidence. The workmanship is thorough, thoughtful, and clearly driven by a deep understanding of these cars. I would not hesitate to recommend Donnelly Racing Services to anyone looking for expert Porsche service and performance work.

I brought my 944 Turbo to DRS for a refresh — oil service; new timing belt, motor mounts, shocks/struts and battery; and troubleshooting and repairing a few additional items. I couldn’t be happier with the quality of the work. The owner of the shop is professional, knowledgeable, clearly loves his job, and it shows. The level of service is also outstanding. The owner listens to your concerns and takes the time to throughly review and explain potential solutions. Every time I spoke with him, I felt like I learned something new without being schooled. Highly recommended.

Exceptional customer service and communication throughout the process. Repairs performed in a timely fashion at very reasonable rates, for a problem that confounded two other Porsche shops. Now my go to guy for all of my 944 needs.
