Carefully Engineered. Built to Last.
Kartboy first gained recognition among Subaru enthusiasts in 1999 for its innovative product design and precision manufacturing. Quality endures.
“Yes, it’s true, Kartboy rocks. I just installed my STi short shifter and it feels great. There is a huge reduction in throw. The parts were top‑notch quality… Quick and easy install with the right tools… way to go Kartboy!”
— Ari Allen on NASIOC
“It’s a great upgrade, and probably the most bang for your buck performance wise for a hundred bucks… The throw is SIGNIFICANTLY shorter… much better over stock… Overall, best $138 mod you can do for your car.”
— evohuntinwrx on NASIOC
“I’ve had Kartboys on all 3 of the Subarus that I have owned, wouldn’t trade them for anything…”“…it turns your car into something completely different!”
