Those guys know their stuff! They got me rolling with the new suspension install. When at the shop all the guys were cool enough to answer any questions. Great place.

I discovered Adrenaline Performance LLC on Facebook after noticing a lack of power in my 2012 MazdaSpeed3. Ryan took fantastic care of the car and he made the experience both educational and interactive. He was incredibly thorough with his work, making sure that no small issue would go overlooked. My car is running better than the day I got it. This was my very first experience with this business and I have already scheduled to return in order to upgrade my suspension.

Awesome experience at this shop! Couldn’t be happier with the price and work I had done. Super nice guys for sure very friendly and helpful. I recommended them to all my friends here in South Georgia already because there aren’t many shops in our area that will do this work if they do they are never happy about it and the prices aren’t fair but Adrenaline is 100% worth the drive.
