PRODUCT DETAILS
Your car says K swap. Your knuckles say 10mm that got away. Now your shirt can say something too. "Genuine Goods" in Japanese kanji sits front and center with our signature hr logo, because that's what we build: parts that are genuine in thought, purpose, and function. Also because it looks cool. Mostly the first thing. Okay, both things. Flip it around and you get HYBRIDRACING! in big weathered kanji across your shoulders, readable from three parking rows away at a meet, which is exactly the distance from which people will nod at you approvingly. The weathered print treatment means it looks broken-in from day one, so nobody has to know you bought it Tuesday.
We print these in the USA on a dark cherry red Gildan Ultra Cotton blank, a heavyweight 90/10 cotton-poly blend with a classic fit. It's the kind of shirt that survives actual shop life: brake dust, burnout smoke, that one coolant incident we don't talk about. It runs true to size, but if you're between sizes or plan to layer it over a hoodie while you wait for your tune slot in January, go up one. Treat the print like you treat your paint: wash cold, inside out, and keep it away from high heat. It'll outlast at least two of your future exhaust setups.
Hybrid Racing Genuine Goods Kanji T-Shirt: Installation Guide
Estimated install time: 8 seconds. 45 minutes if you're the guy who "doesn't need instructions."
Difficulty: 1 out of 10. Easier than a valve adjustment. Harder than admitting the noise was there before you started.
Tools required: None. Put the impact gun down.
Before You Begin
Inspect the shirt for shipping damage. There won't be any, but you check every box you receive like it owes you money, so we're not going to stop you now.
Verify fitment. This shirt fits the following chassis: yours. It does not fit your buddy who "wears a medium" but hasn't worn a medium since the EP3 was in showrooms. Refer to the size chart, not to his self-image.
Torque spec: hand tight. Do not use anti-seize.
Installation Procedure
Step 1: Remove old shirt. Retain hardware (your other shirts) in case rollback is required.
Step 2: Orient the new unit. The Genuine Goods kanji faces forward. The big HYBRIDRACING! kanji faces the people walking up behind you at the meet to ask what the swap made on the dyno. This orientation is critical. Installing the shirt backwards will not damage the shirt, but it will damage you socially.
Step 3: Insert head through the large opening. Not one of the small ones. We shouldn't have to say this, but Kendall has heard things on the support line.
Step 4: Insert arms through the remaining openings, one per side. (Simultaneous insertion is for advanced users only.)
Step 5: Pull downward until fully seated. You should hear no click. If you hear a click, that was your back, and it's unrelated to this install.
Post-Install Checks
Walk past a mirror. Nod at yourself the way strangers at meets are about to nod at you. Test at operating temperature by standing near someone doing a burnout. The weathered print is pre-broken-in from the factory, so there is no break-in period. Drive it like you stole it immediately.
Maintenance Schedule
Wash cold, inside out, away from high heat. Service interval: whenever it starts smelling like 90 weight gear oil, or when someone in your household files a complaint, whichever comes first. Do not resurface, machine, or shave the print to save weight. It's already lighter than your flywheel.
Troubleshooting
| Symptom | Diagnosis and Fix |
| Shirt feels tight | Check for interference from winter hoodie layering. If clearance issues persist, you needed to go up a size like we told you on the product page. Warranty does not cover reading comprehension. |
| Friend keeps borrowing it | Known issue. The only fix is buying a second unit. This is the same friend who materializes exactly four minutes after the subframe is back in the car, so honestly, he hasn't earned it, but we're not here to referee. |
| People keep talking to you at gas stations | Working as intended. No fix available. |
