Dan and Pat started the shop in 2013 out of their Grandmother's garage. Since then, the 2-man shop has drastically expanded and now they service many clients in the Metro-Detroit area. At Grandma's Speed Shop, "We know you by name, not just another number. We guarantee that once you get to know us, you will never go anywhere else!"
Here at GSS, we are a small family owned and run shop. We truly know our customers! Let us put our expertise to work for you. Whether its an oil change or a custom twin turbo setup, we can handle anything! Unlike other shops where you need to schedule an appointment, just stop on by! When you come in, you will end up speaking to one of the owners, Dan or Pat.
