About
The first KDM-only shop in Tennessee.
One bay in Clarksville for Hyundai, Kia and Genesis: parts at dealer price, installed, flashed and logged in the same place.
The story
Why this shop exists.
Middle Tennessee KDM is a Hyundai, Kia and Genesis performance shop in Clarksville, Tennessee, the first in the state to work only on these cars.
It started with a gap. No brick-and-mortar KDM specialist exists in Tennessee, Kentucky or the wider Southeast. A Clarksville owner orders parts online, finds a general shop that has never seen an N car, then mails an ECU to Virginia or Toronto.
We built one bay to do all of it. We are a certified dealer and installer for LAP3 USA, N75 Motorsports and SXTH Element Engineering, and we source N-car parts from KDM Tuners, all at dealer pricing. A technician who works only on these cars installs them, the tune is flashed here, and the datalogs are reviewed on the road. Every job is quoted in writing before we order a part.
We buy from the people who make the parts, not from a retail checkout. The shop is owned by Devin Franco, with co-owner Aries Johnson, who also runs Project 215, the studio behind this site.

Every car in our bay is worked on by a technician who does only Hyundai, Kia and Genesis: the install, the bench or OBD flash, and the road datalogs.
