Mahdavi Motorsports

What Mahdavi Motorsports does

Mahdavi Motorsports is a privately held, founder-owned automotive performance and custom fabrication shop founded in 1999 by Sam Mahdavi and his brother in Lilburn, Georgia. The firm's core business is custom car builds, engine swaps, turbocharging and supercharging systems, performance tuning, and full-service auto repair, with a stated track record of 1,000+ engine swaps across all makes and models (including 2JZ, H22, LS/LT, and Coyote installations). The shop is differentiated by its ASE certified staff, which includes two Master Mechanics, and by certifications in COBB Tuning, AEM Performance Electronics, HP Tuners, and HONDATA ECU platforms. Vehicle output spans individual customer projects (such as 1992 Chevy Camaro sleeper builds, 1972 Oldsmobile Cutlass 442 LT1 swaps, and 1957 Ford Thunderbird frame-off restorations), race car preparations, and content vehicles showcased through media.

The business model is direct-to-consumer and project-based, generating revenue from four streams: custom car builds, general auto repair and maintenance, performance tuning, and television production via Sam's Garage TV show in partnership with Powerscope Productions. Pricing is quote-based for custom builds with no publicly disclosed standard tiers, and the business operates from a single physical location in Gwinnett County, GA. The customer base is segmented into automotive enthusiasts, general repair customers, the racing community, and classic car restorers, with no enterprise or B2B concentration apparent.

The company's go-to-market is heavily media-driven. Sam's Garage TV Show airs nationally on Velocity, MAVTV, and REV'N Networks (currently in its 2025 season, 5+ seasons total), Sam's Garage Radio Show is syndicated nationally on AM680 WOGO and AM920 The Answer, and the firm maintains a YouTube channel (14,700 subscribers), an Instagram (@samsgaragetv, 153K followers), and a Facebook presence. Brand awareness is further amplified by movie credits (10+ vehicles provided for the Fast & Furious franchise), a 2008 Speed Channel PINKS victory, two NDRA Drag Racing Championships, a 2004 SEMA Installers Challenge participation, and consecutive "Best of Gwinnett" (10 years) and "Best of Lilburn" (9 years) recognitions.

Direct peers

• Gas Monkey Garage: Richard Rawlings' Dallas-based custom car shop and Discovery TV brand (Fast N' Loud). Closest analog: independent custom builds combined with a nationally televised show built around the founder personality.
• West Coast Customs: Long-running custom vehicle builder founded by Ryan Friedlinghaus, with TV presence and celebrity/entertainment clients. Directly comparable custom-build-plus-media business model.
• COBB Tuning: Aftermarket performance electronics and tuning platform (AccessPort) where Mahdavi is a certified installer. Comparable platform-leader in the same tuning ecosystem Mahdavi monetizes.
• HP Tuners: ECU tuning hardware/software (MPVI2) provider used by Mahdavi for performance calibrations. Comparable as a tuning platform whose installer network mirrors Mahdavi's service offering.
• PRL Motorsports: Honda/Acura performance parts manufacturer and turbo system specialist that appears as a Mahdavi partner. Comparable as a performance aftermarket brand operating in the same Honda/engine-swap ecosystem.
• HONDATA: Honda performance ECU company (FlashPro) that Mahdavi is certified on. Comparable specialist tuner in the same Honda engine-swap and tuning category.

Broad incumbents

• Edelbrock: Long-established aftermarket performance parts manufacturer. Comparable as a broad incumbent in the same aftermarket performance category, but at much larger scale and with own-brand products.
• Summit Racing Equipment: Large mail-order and retailer of performance parts and accessories. Comparable as a dominant aftermarket performance distribution channel Mahdavi's customers buy from, though at vastly larger scale.
• APR (Auto Performance Racing): Larger VW/Audi performance parts and tuning company with broader product line. Comparable as an aftermarket performance brand, but operating at significantly larger scale.

Emerging players

• Bisi Ezerioha / Bisi Motorsport: Independent performance shop and media personality focused on imports and engine swaps. Comparable as a smaller specialist engine-swap shop with content presence.
