About J-Spec Garage

J-Spec Garage is a US-based specialist in genuine Japanese performance parts, headquartered in Panama City Beach, Florida. We're the enthusiasts' source for the JDM platforms that defined a generation — the Toyota Supra and 2JZ-GTE, the Mazda RX-7 and 13B rotary, the Nissan Skyline and RB26, the 240SX and SR20, and the R35 GT-R — and we back every order with real domestic inventory, fast shipping, and a team that actually builds these cars.

Who We Are

We started J-Spec Garage because sourcing quality JDM parts in the United States was harder than it should be. Enthusiasts were stuck choosing between mass-market components that were never engineered for their power goals and overseas suppliers with unpredictable quality, fitment, and lead times. We built a different kind of shop: a deep, platform-specific catalog, stocked domestically, run by people who understand the engines and chassis we sell parts for.

Today J-Spec Garage carries thousands of products across the most sought-after Japanese performance platforms, from OEM rebuild components to the billet hardware that serious builds demand.

What We Specialize In

The Only Authorized US Distributor of RaceOnly

J-Spec Garage is the only authorized US distributor of RaceOnly — the precision engineering brand that manufactures billet CNC components specifically for the 13B-REW, 20B-REW, and the broader rotary platform. No other US retailer carries genuine RaceOnly parts. That means one domestic source, stocked and ready to ship, backed by a team that knows the rotary engine inside and out. Learn more about RaceOnly and why we're the exclusive US source, or shop the RaceOnly Collection.
