Fans of high-horsepower G-body muscle recognized Killer Mike’s Buick Grind National the moment the car rolled onto the red carpet at the 2024 Grammy Awards. The exterior packed heavy custom style and aggressive street presence, but the original cabin desperately needed an overhaul to match the mechanical attitude underneath the sheetmetal.
Automotive industry veterans Mike Musto of Hemmings and Ron Baugh of American Racing brought the famous Buick Grind National directly to the TMI Products team. They challenged the upholstery experts to build a custom seating layout that rivaled the serious performance modifications hiding under the hood.

Technicians rolled the black G-body into the TMI Design Center and installed a full Complete Interior in a Box package. The fresh materials replace the aging factory components, giving the owner a comfortable space to control the massive horsepower. Applying this kit gives the classic muscle car a modern feel without losing its aggressive identity.
Enthusiasts can finally see the completed Buick Grind National up close during the 5th Annual Cars & Clearance Event in Southern California on Saturday, August 15. The outdoor gathering brings local gear heads together to appreciate custom rides while supporting a charity backpack drive benefiting The Salvation Army. Connecting a legendary hip-hop artist’s build with a local community event creates a great excuse to spend a weekend surrounded by loud engines and custom upholstery.
If you plan on attending the weekend meet, what specific interior details of Killer Mike’s customized G-body are you looking forward to seeing the most?
