The Best Performance Shop Around

Hands down the best performance shop around. Work is done on time and on budget. The communication between customers and staff is unparalleled. They have worked on 3 of my cars and I wouldn’t trust anyone else in the area for any future work. I highly recommend giving them a call for any automotive work.

Overly Satisfying

Tim and the entire team at Olsen Motorsports are a credit to the Porsche community. With dozens of combined years of experience, these guys are capable of making your wildest automotive dreams come to life. I handed over my 911 with confidence and picked it up 3 days later smiling ear to ear. Communication was fast and easy and the final product is overly satisfying. I will be back and highly recommend Olsen Motorsports.

Overly Satisfying

What a great guy... Tim is friendly, knowledgeable, and very professional. He did an excellent job on my 991 C4S, replacing the breaks, spark plugs, filters..
I Look forward to continue working with him in the future. Thank you Tim!
